Britax Frontier 90 Review

When the Britax Frontier 90 was released, we did a quickie review of the new Harness-2-Booster Britax Frontier 90 with the ClickTight installation system. We have been given the opportunity to look more in-depth at the seat, and are excited to share it with you!

When Britax announced the release of the new Frontier 90 and the Pinnacle 90, I will admit that I was pretty skeptical. As a CPST I’m used to sweating, struggling, and wrangling seats to get them installed properly. And that can only happen after figuring out whether to use lower anchors, or seat belt and determining how the seat belt locks, if I need a locking clip, or if there is a lower anchors weight limit I need to account for. 

Confusing, isn’t it? Thus my hesitancy – surely it couldn’t be that easy to install. I watched the videos, attended Britax webinars and slowly, I began to get excited. This kind of technology is a game changer – when seats are this easy to install, it increases the chances that they’ll be installed correctly the first time.

When the Frontier 90 showed up at my door, I squealed like a child on Christmas morning. I immediately opened it and, like a good CPST, read the manual from cover to cover. Unboxing the seat was very straight-forward – no assembly required.  Open the box, take off the plastic, read the manual, and you are good to go. Once the seat is out of the box, you are directed right towards the Click-Tight technology.

Before installing it for the first time, I had to play with the harness heights.


Britax Frontier 90 has nine different harness positions

Britax Frontier 90 has nine different harness positions



The Frontier 90 has nine different harness positions; the lowest measuring 12.5″ and the highest measuring 20.5″.  It is the tallest harness height available, not including special needs seats. The seat features a no-rethread harness, which makes adjusting the harness heights for multiple children a breeze.  The harness adjusts from the top of the restraint, this is a nice improvement over the Frontier 85, which required the seat to be uninstalled to adjust the harness height.





Britax Frontier 90 crotch buckle positions

There are two different crotch buckle positions and switching the buckle positions is so easy that it can be done without uninstalling the seat. There is no removing the buckle, simply slide it from one slot to another.

Another benefit to this buckle is the EZBuckle feature: it flips forward when not in use, which means no more digging under bums to find buckles!

The moment of truth!  Is it really that easy? Without hesitation, I can say that yes, it really IS that easy. A solid, correct installation without fighting, sweating, and wrangling.


This picture shows the inside of the seat, where the Click-Tight technology lives.

To install, thread the seat belt through belt path as directed by the green arrows, as shown in the picture on the right. Next, fasten the seat belt and shut the compartment. Finally, the only thing left to do is to attach the tether anchor, and you are good to go! Remember that this review does not replace the instruction manual, please refer to it for full installation instructions. Additionally, the Britax Frontier requires use of a tether anchor when used in harness mode for a child weighing more than 65 pounds. For our friends in Canada, tether use is required on any forward facing harnessed seat.



For your viewing pleasure, I made a video.  By the time I had made the video, I had installed the seat in about 7 or 8 vehicles, but it was just as easy the first time I did it.

Using lower anchors for installation is equally as easy, but remember that lower anchors do come with a weight limit. The Frontier 90 weighs 25 pounds and depending on your vehicle, a lower anchor installation may be short-lived.

The lower anchors come neatly bundled inside of the ClickTight compartment. To do a lower anchor installation simply attach the lower anchors and close the ClickTight. Once again, you have a rock solid installation with no hassle.


When the lower anchors are not in use, they stow neatly inside of the of the ClickTight compartment.


Once installed, it makes for a very comfortable seat.  The EZ-Buckle really does make a difference when strapping the kiddo into the seat.


Fit to Child

Harness Mode

Britax Frontier: 3.5 years old, 34 lbs., and 39.5 inches tall



The model to the left is 3.5 years old, 34 lbs, and 39.5 inches tall. Her opinion of the seat can be seen in her smile.  In words, she calls it comfy and soft.  Sleeping in the seat has also proved to be comfortable, and we have not seen any head slump.




Britax Frontier 90, FR90, FR85, hbb, booster, combination seat, LATCH, FR85, click tight

Britax Frontier: 8 years old, 49 inches tall, 90lbs.



The model to the right is 8 years old, 49 inches, and right at the 90lb. limit of the seat in harness mode.  Even right at the limits, he still fits into the harness well, and comfortably.








Booster Mode

Part of the seat’s name is Harness-2-Booster.  So how does the seat stack up as a booster?  Excellent! One of the downfalls of most combination harness and booster seats is that you need to uninstall the seat to remove the harness straps to switch it to booster mode.

With the Frontier 90 you are able to switch to booster mode without totally removing the harness straps and uninstalling the seat.  The crotch buckle can be laid down, and the bottom cover fastened over top of it.

To release the harness there is no re-threading through small slots.  Open the ClickTight compartment, and on each side, there are holders for the harness, as shown in the picture on the above right.

Slide the harness off of each side, and close the compartment.  Then roll up the straps, and tuck them under the sides, as pictured to the left.

So how is the booster fit?  Perfect!  The model to the right is 6 years old, 45 lbs., and 48 inches tall.  The belt hits low on the lap, and correctly on the shoulder.  Lower anchors can be used to secure the seat in booster mode.


One thing that is important to note, the recline mode cannot be used while in booster mode.

Here, our 8-year-old model displays the fit in booster mode.  He’s 8 years old, 89 lbs. and 49 inches tall. for good measure, we wanted to show where the lap belt sits.








There are a few cons about the seat that I found, but they are minimal.  This leads me to the next downside to the seat.  It’s HEAVY!  It weights 25 lbs.


Important Information: Where to find

FAA Approval: Great news! The Frontier 90 and Pinnacle 90 are now FAA approved for use on an airplane. To install on an airplane, leave the ClickTight panel closed and run the airplane lap belt over top of the ClickTight compartment.   We travelled with a Frontier and wrote about the experience.


Head to Head Comparison: Frontier 85 vs Frontier 90

How does the Britax Frontier 90 compare to its predecessor, the Frontier 85?  In terms of installation, there is no comparison.  I was a huge fan of the solid installation that the long belt path on the Frontier 85 gives, but there is a substantial learning curve, when using the long seat belt path. The Frontier 85 also has some quirks, like the recline block being forward for harness mode, and backwards for booster mode.  Also, to access the full height of the seat for booster mode, you need to remove a screw at the back of the headrest to extend it.  The Frontier 85 has three slots for the crotch buckle, and the Frontier 90 only has two, but that doesn’t seem to interfere with the performance of the seat.  The distances seem to be a happy medium of the three buckle slots.


Now, onto some pictures.  First up, side by side comparisons of the Frontier 85 and Frontier 90 in the lowest slot for harness, and the highest slot for harness.  Keep in mind, the Frontier 85 has a screw that is required to be kept in place for harness mode.  The Frontier 85 has a top harness height of 20” and the Frontier 90 has a top harness slot of 20.5.”

So lets take that screw out and check the heights to their full limit.  I will admit, I was a little shocked about the differences.  Given that the Frontier 90 has a higher harness limit, I thought that the headrest would extend farther.

Given the differences in height, I was curious about the height of the belt guides.  There is about an inch of difference between the two, with the Frontier 85 being a taller belt guide.

Overall Thoughts

Britax Frontier ClickTightMy overall opinion of this seat is that Britax hit the nail on the head with the Frontier 90 for a long-lasting combination seat that is easy to install. It also turns into a long-lasting booster that provides a great belt fit.  This seat is impressive not only to CPSTs , but parents, and grandparents as well.

I have shown my Mother AND Father in law the installation, and both agree that the ease of installation is amazing, and it takes away the guesswork.  They said it makes them feel confident that they can install the seat correctly, and know that their grandkids are safe. Even my husband, who is usually bored by my car seat talk, agrees that the Click-Tight Technology is exciting.

  1. The clicktight installation is definitely my favorite feature. Lbp is great for our Frontier 85, but it definitely takes me some time to get it right and I don’t trust anyone to install it outside of my DH and myself!

    • My Favorite feature about the Frontier 90 would be the fact that Britax actually puts the recommendation of two years old before turning your child front facing in the seat.

  2. I love the easy Install. I would Love to win this seat for My wiggly newly 4 year old Boy. The easy install would make car pooling with friends so easy in the summer. :)

  3. I have the Frontier 85 for my 5 year old son and we love it, but I would love to have the Frontier 90 so that I did not have to uninstall the seat to raise the harness.

  4. I love that this seat doesn’t need to be re-threaded to move the straps up or down. Favorite feature hands down.

  5. I am so excited at how easy the installation seems! We have a Roundabout 55 and while it’s a great seat, sometimes installing it is a big pain.

  6. I am in awe of the install! We have the 85 and I love/hate it just because of the cursed install. I’m so tempted to upgrade just for this fancy easy installation.

  7. This looks like a great seat my three year old is close to out growing her rf seat and i would love to have this seat.

  8. I love this seat, currently my daughter is in a Nauti, but this oh man I wish I could afford one.

  9. Thanks for the great review!! I really need one of these for my tall son! :)

  10. Great review! I had the chance to “play” with this seat at Buy Buy Baby and was very impressed! My oldest son would love the opportunity to have this seat :)

  11. I love the ease of installation and the extended weight limit for the harness compared to other seats

  12. While I love the idea of the ClickTight technology I also like being able to convert to a booster without removing the harness. I often have a wide range of kiddos in my car & that will make switching between ages/sizes much easier.

  13. Love the new seat! Looks great and so easy to use. Can’t wait to try it out for myself. I think the Easy Click looks awesome

  14. I love the click tight technology, having a 3 1/2 year old who loves to run around while mommy works on car seats, it’s a great fast, and easy install!

  15. Forgot to mention… my favorite part would be that my mom who has issues with arthritis and getting our current car seat tight in her car would easily use this seat with the click-tight technology! So great!

  16. I love the click tight feature!! I’d feel good about letting others install the seat.

  17. My favorite feature is that the seat can remain harnessed until 58″ tall! My son has autism, and I hope to keep a harness on him as long as possible.

  18. I would love to with the carseat. I’ve been looking into getting my 4 year old back into a 5 point harness ever since I found the CSFTL page on facebook.

  19. This review couldn’t have come at a better time as i was researching the comparison between the Frontier 85 and 90 this morning! This blog answered the last few questions i had and made the answer obvious! :)

  20. Seat looks great!!! My LO isn’t there yet, but with one on the way, we could use an extra seat!

  21. Would love to win this for my 4 year old and the click tight installation looks awesome!!!

  22. I would love to own this seat! The east install looks great, as well as the longevity of the seat!

  23. I love the higher weight limits for the harness & booster installations!! I need 3 of them though. Yikes!!! This will mean though that I don’t have to buy a new vehicle yet to transport my 3 boys safely.

  24. What an informative review! And an awesome opportunity! I love how long it can harness for my tall kiddos :)

  25. I love the instillation as our big truck doesn’t have a latch system and getting a seat tightened down in it can be a challange this would be awesome to have and use.

  26. I’d love to win this for my five year old! I like that I can keep her harnessed longer.

  27. I love the easy install! Even my husband couldn’t screw this up, and that would give me great peace of mind!

  28. The clicktight installation is my favorite but I also LOVE LOVE that I don;t have to take out the seat to adjust the headrest!! I wish my Frontier 85 had that!!

  29. This would be amazing for my little! I love how easy it looks to install and use and at this rate my daughter could be harnessed til she’s 12 with those limits!

  30. Thanks for the great review.. only thing I am left wondering about is what the actual weight limit is on the latch install?!

  31. I’m waiting until my 2 yo outgrows her Radian RFing but I would love to have this seat.

  32. I love how easy it is to strap into the car. Not having to shove your whole arm through the base of a car seat?! What a dream!

  33. I’ve never owned a britax but I would think easy install would end up being my favorite feature lol!

  34. I would love to have this! I have a Frontier 85 and it seems like all the things that make it a little difficult have been updated and made easier, especially the click-tight install. LBP can be a little tricky!!!!!

  35. I love that the installation is easy and I have to give major props to Britax for having a minimum age of 2 years old.

  36. I found the 85 to be pretty easy to install, but I am blown away by the install on this 90! I hope they start incorporating it into more seats!

  37. I would LOVE to win this seat!! The installation looks so easy and would be a good option for grandparents to use when they take our daughter!! Thanks so much for doing this giveaway!!

  38. This seat seems amazing! I was aware that this seat was coming out, but was not sure it was going to be as good as the video on the website showed. So glad that you were able to give it such a great review. I will definitely be keeping this one in mind :)

  39. I love how easy this seat is to install. It makes moving it between cars a little easier if and when that is necessary and also makes you feel better that you did install the seat correctly.

  40. I’m thrilled a company like Britax makes a seat that keeps our older children safe and offers the 5 point harness. It is a great way to give parents peace of mind!

  41. I’m loving the ClickTight install system! Even my husband and parents can figure this out!

  42. Did they change the belly pad? It looks like it is more likely to stay on. My frontier 85 I’m always digging for the crotch buckle and the belly pad is forever falling off!

    • They did change the belly pad! That is part of the EZBuckle! No more digging for the crotch buckle!

  43. I love this technology! My youngest is soon to be 8 and still very much in need of a seat. I do everything I can to keep my littles safe!

  44. I love how long my child can be harnessed in this seat and the fabric patterns!!! I hope I win!!!

  45. i would love to win!! my daughter and son might be fighting over the red congo seat!! :)

  46. We are in need of a new seat for my 5-year-old son. It would be such a blessing to win a fabulous seat like this!

  47. I love so many of the features. I love the click tight the best as installing from vehicle to vehicle should be so easy and even easy for those that don’t use car seats very often to install it. So much less room for error that way.

  48. I love the easy install. The seat we have now is HORRIBLE, it took us an hour and a half to get it in.

  49. I will have to keep this seat in mind when our little one gets old enough. The lady at Babies R Us said that Britax made the best next step up seat. Anything that is easy to install is great! I hate that it takes a degree to install a car seat properly.

  50. I love the easy installation, but also the really high harness heights.

    • The comments section was not working right for me… this one should have my correct email address.

  51. I love the Click Tight install feature. We wouldn’t worry about a correct install when she is with Grandpa.

  52. My favorite feature is the 90-pound Weight Capacity in Harness Mode… because my 4 month old is already 20 lbs!

  53. Favorite feature is ease of use when adjusting harness height for different or growing kids, or switching from harness to booster mood with different kids.

  54. The click tight technology is definitely my favorite! Nothing better than an easy, always correct installation!

  55. This seat looks awesome! It is user friendly and will fit my daughter now, at three, until she is much larger!

  56. The Click Tight installation and the fact that the harness weight limit is so high! I am in need of a seat to replace my son’s booster in our SUV and this would be PERFECT. He needs something with a 5-pt harness because he’s Autistic.

  57. My favorite feature is the height and weight limits. We have very tall children! My oldest son is in a Frontier 85 and we absolutely love the seat. I would love to have a Frontier 90 for my middle son who will need to move to front facing shortly due to being very near to outgrowing his current seat by height.

  58. This seat looks fantastic my favorite feature is the super easy install and also the fact that it can be used to 90lbs!

  59. My favorite feature of the Britax Frontier 90 is a tie between the ClickTight installation system and the up-front harness height adjustment!

  60. I loooove that it harnesses to a high weight! The easy install is nice too, but I’m not afraid of getting sweaty while getting a seat in right!

  61. I love all the safety features and that it is a long term seat!

  62. The clicktight instalation is probably my favorite aspect of this seat – it looks so simple!

  63. The seat looks great. With a new baby on the way i will definitely be looking into a Britax.

  64. My favorite feature of the Frontier 90 is the super easy install with the Click Tight!

  65. I love Britax! We have two right now, but we have 4 kids, the youngest of which is about to outgrow her infant carrier and move into her sister’s Marathon. which means the older sister needs a new seat! This would be perfect! I love the easy installation!

  66. I would love this seat for my daughter when I decide she’s ready to turn around. The easy installation has me so excited!

  67. I like the no-rethread harness and the Click Tight Technology. I’ve never used a Britax seat before but I hate having to thread the seatbelt.

  68. Love the click tight and the long lasting harness it would be awesome for my son when he turns FF at 4

  69. I like the easy installation and the fact that I can keep my little safer longer!

  70. I love the easy install. Would absolutely love this seat for my super tall 3 yr old!

  71. I like that this can change from harness to booster mode without removing the harness straps. I really want this for my 5 year old!

  72. I love the easy install, but my favorite feature is the higher weight and height allowances. I want to keep my 6 year old (and then 4 year old then 4 month old passing down) harnessed as long as possible and this would allow for that. What a great giveaway!

  73. Overall, my fave feature would be the easy install for teh general public. I also love the high harness height for those tall torso kids and the easy adjust harness makes me super happy.

  74. I love that it keeps older larger children harnessed having boys that are unable to sit still for any length of time I feel they are safer in a harness and they will stay harnessed until no longer possible!

  75. Would LOVE this seat for my 3-year-old son who is still rear-facing at 30 lbs and 36″ for when he outgrows his Britax Boulevard. Thanks for the offer.

  76. I love that it is taller than most other car seats. We currently have an Avocate 70 CS, and I am really afraid that my daughter will outgrow the hight max before she is really old enough to switch to a different kind of car seat.

  77. I love the fabric, the Click tight install system and the fact that this seat will keep my daughter harnessed for as long as possible. :)

  78. I would love to win this for my daughter! I love her Britax Convertible seat, but I think the seat will expire before she ever outgrows it! I would really like one for all three of my kids. I hate the Graco seat my 6-yr-old is in because it a pain to install, plus, he is about to reach the max weight for the harness and I don’t want to switch to a booster yet. The only reason he has that seat is that he was with my husband in an accident and they had to go to Walmart to get a new seat to get home and that is all they had. (He was in a Britax during the accident and only ended up with belt burns on his shoulders, and the van was totaled! I have never been so thankful to be so anal about getting the seats installed correctly and kids buckled in right.)

  79. I really like your thorough review. I am glad to see a carseat that my child can grow into in the future. I am glad the minimum requirements to forward face are so high. I am still looking to wait to turn my 25lb 2 year old around. This makes a good option for our next seat.

  80. This is an amazing seat. I would love to have one. I love the fact that I wouldn’t have to fight with a the belt lock and threading and retreading the seatbelt over it locking before I needed it to.

  81. My favorite thing about the Frontier 90 is the easy install. This will make a great seat for my 2 year old when the time comes for us to stop rear facing.

  82. My favorite features are the higher harness weight limit, and the click tight technology! :))

  83. My favorite feature is definitely the height and weight limits. Such a long lasting seat.

  84. I think this will be my next seat once my toddler needs it (still easily rear facing at 2 years, 7 months)!

  85. My favorite feature is the easy belt path install – making sure that all who transport my child will be doing so correctly.

  86. Man, I would love this for my 5 1/2 year old! He’s harnessed in a Frontier currently, but the oldest style, before the 85. I would love to harness my 7 year old again too! She outgrew the old style Frontier recently at 49in tall. This one would buy us a little more time.

  87. I absolutely love every feature on the new Britax Frontier 90. Britax never fails to include every feature a car seat should have and their safety standards are impeccable!!!!!

  88. I love the easy Install. Makes it easy for the Grands & others to install so that I know its correct.

  89. I bought a cheap car seat last year and regretted it afterwards. It’s safe, but hard to install and won’t last him very long. I love the longevity of this seat!

  90. I would LOVE to have this seat for when my little man outgrows the Marathon he’s currently in!!

  91. The harness height and high weight limit are the key for me! My step son will be 8 in July and he still has many pounds and many inches before he’d outgrow the harness!

  92. The clicktight installation is what cinches it for me. I have always loved these seats, but opted for the Diono Radian because I wanted the RF-ing option as well. Now I want to move my 7 year old back into a harness, and this would be PERFECT for her. She’s just so tiny, I will feel better with her in a harness.

  93. I love how easy this seat looks to install. With so many old cars about in our family would save a lot of stress when car pooling and not need locking clips and dealing with wide seat belts that cause the seat to install poorly.

  94. I love how easy it looks to install and that when the kids are fighting over where to sit I won’t have to wrestle with the seat just to adjust it to fit the child.

  95. The Click Tight has to be my favorite feature. As a Tech, I think this will help reduce the occurrence of loose installations :)

  96. I really like the ease of install with the seat belt. Britax is miles ahead of the competitor with this seat.

  97. What’s not to love about this seat!? I think the best part though is the ClickTight Installation System.

  98. The Click Tight technology is my favorite feature. It would make instal so much easier and faster.

  99. I love the click-tight installation. I also appreciate the height/weight limits. I have a tall four year old and this will do wonders for us.

  100. I LOVE the Click Tight technology! My 5 year old is 40 lbs so we have to use the seat belt install and it takes a lot of sweat and muscle to get it in correctly. This would save me so much time and hassle!

  101. I have always wanted a britax carseat, they are just never in the budget. I am always looking for a carseat where I can harness my daughter longer as she is so small.

  102. Great seat and super easy to install. Could be the perfect seat for my parents/grandparents that struggle with installing seats :)

  103. I love easy to install seats. Anything that is going to prevent me from sweating so much is great.

  104. On a personal note my fav thing about the Frontier 90 is for sure the easy install…However on a more broad note the min age of 2 for sure I hope other car seat manufactures will follow them on this one:)

  105. My favorite feature is the click tight easy install. We have a little one with Down syndrome who will be in a car seat for quite some time. The fact that this car seat is both incredibly safe and easy to install makes it our top choice! it will definitely be the car seat that we purchase when we’re ready to transition into a larger seat in about 5 months.

  106. I love absolutely everything about it! I prefer to 5 point harness as long as possible for my boys.

  107. I love the ClickTight. Such a game changer. I’m hoping Britax (as well as other manufacturers) bring similar technology to their installs.

  108. It’s all around easy to use! I LOVE that it doesn’t have to be uninstalled to adjust for a different passenger and LOVE how easy the installation is-both HUGE bonuses when you are talking about a seat for a child of that age.

  109. Awesome review! I’m excited how easy this seat is to install. We have the Frontier 85 SICT and it can be quite cumbersome to install if we have to move cars.

  110. I love the 90 lb harness limit and the super easy install! So nice when you switch it between vehicles!

  111. I love the safety and quality of the brand in general, but click tight does sound like a user friendly feature.

  112. Front adjust harness is my hands down favorite feature! That and the stay in place crotch piece! I love that is is more narrow than the F85 and love the Safe Cell Technology too! I also love how easy it to install and could actually feel safe with somebody other than me installing! So many wonderful features!!!

  113. I love this concept. We have a car seat that we purchased 2008 – SafeGuard, that I absolutely love. 7 year warranty, etc. But I can not find any more on the market and have no idea what happened to the company. I especially loved the belt tightening feature, which I haven’t seen on any other seats. I’d love to find it or something similar. But this sounds equally as good, probably one of the first designs to come close in ease but in a different area. My husband deploys frequently (currently on number 5 in 6 years) and I need to be able to feel secure when I move the seats around. Right now I really am not comfortable that I”ve done it right.

  114. Love the click-tight! We have a Britax 85 for my DS and love it. Would love to win a 90 for my DD.

  115. I love the ease of the click tight install. Would be a great seat for my 5 yr old whose not booster ready

  116. The easy install is definitely it’s biggest advantage, but I also really like how long it will last!

  117. I love how high up the harness can get to since I plan on harnessing my daughters until they are at least 6 years old. Lesley McKissick

  118. Oh, this review made me want this seat even more!! Hopefully I can win. I love the ClickTight technology, now I never have to second guess my husband’s or parent’s install.

  119. I love the ease of install with the click tight technology. Britax is just awesome!

  120. I love the easy buckle and the harness bc I would want my 5 yr old to still be in a harness vs the booster he has now that we have to dig around for the seatbelt since we have another carseat next to him.

  121. I LOVE the click tight technology! And I just love the brand! We have two convertible britax carseats for our boys (3 years and 17 months) and while we love the carseats, they’re a pain to install. Our 3 year old is very tall like his daddy and will soon reach the height limit for his carseat. My husband and I were worried about finding him a taller carseat with a harness and this has come out at the perfect time!

  122. I love that this seat solves the annoyances of our two Frontier 85s. We love the seats, but having to uninstall to adjust is a hassle , as is re-installation. As some have noted, I don’t trust anyone else besides DH or myself. Also, does this F90 have a seat cover that stays hooked at the bottom?? That’d be awesome.

  123. The click tight would have to be my favorite feature since the frontier 85 is a beast to install in my vehicle!

  124. I like that it is for taller kids. My son is only 2 but measures a year older on the height / weight scale.

  125. I love the height limits. As a momma with tall children, it’s so important to have a harness seat that holds taller people!

  126. This would be great for when I turn my son FF- he has a while to go at 22 months old and I have no plans on turning him AT 2 lol. Seems like great features and easy to use!

    Wish it was FAA compatible with being a military family though.

  127. Love the weight limit and height limit. My daughter is 4 and because she is 64lbs and over 45inches tall its really hard to find a seat for her. All the car seats that can fit her are way to expensive and unfortunately I can’t afford them after losing my job and being a single mother with zero help from her father.

  128. Everything!!!! I just love the over look, the Britax name, the high height limits, and the super easy installation.

  129. Everything!!!! I just love the over all look, the Britax name, the high height limits, and the super easy installation. We’ve owned a lot of Britax seats.

  130. This seat would so nice as far as install because I have to switch our current seat between my car and my mothers car. it would be nice to know that little would be safe with the easier installation. I also love that it would be the last car seat I would have to have for awhile!

  131. I love that it coverts to a booster so easily. That would be such an amazing feature for me as my almost 8 year old is almost completely booster trained and I will be starting to train my 6 year old soon. Then I still have 2 more who will get use out of it within the next few years.

  132. The 9 year expiration and high weight and height limits. When I turn my little guy around I want this seat to last him until he is full size!

  133. Favorite feature would be the click tight technology making for an easy installation!

  134. I’d say one of my favorite features is the most obvious … they Click-Tight technology. That’s just wild! After so many years to struggling with making sure I can get my child’s car seat installed as tightly as possible, this would be so nice to have! I also like that they’ve made it easier to adjust the crotch buckle as I recently just struggled with moving my sons so I could move it to a different position! lol

    Thank you for the opportunity to win & good luck to all!

  135. What is your favorite feature of the Britax Frontier 90?

    The fact that I could harness my 9 year old in it! AWESOME!

  136. I love that its easy to switch from kid to kid. I don’t have kids of my own but am often carting around kids of all ages. One

  137. Of these would make life easier. I currently have a convertible seat that I use for the under 40lb set and a backless booster. For the innetween kids I’m alway having to borrow seats.

  138. My favorite feature is the easy install. I wouldn’t have to worry about it when my husband installs the seat. Second favorite is how long the harness lasts.

  139. The easy switch from harness to booster sounds great! I could easily use it for both my kids, or when I need to carpool with a younger child.

  140. I really like the booster option. I currently have a Radian XTSL (I get the letters mixed up, but the one from Sunshine Kids before being Diono) and love it, but this one does not go to a booster, so the feature I like for the Britax is the booster seat form.

  141. I love the safe cell & click tight and might actually trust someone else (daddy & Nana) to install and use this seat correctly!

  142. I would love this seat for my 6 year old. The high height and weight are such great features and so is the easy install!

  143. i love this seat so much. Good height and weight max for my chunky 5 year old or my tall and skinny 4 year old!

  144. Love the easy installation and the safety features . The comfort feature is a plus also :)

  145. I love how easy it is to install! We have one seat in my mom’s car that is terribly difficult to install & my husband is the only one who can do it correctly. Kind of a problem if I’m dropping my daughter off at my mom’s by myself & they had to remove the seat for cargo space. One time I had it about 95% installed correctly & had to send my mom off down the road to meet my husband so he could fix it.

  146. I’d love this seat in the cactus flower print! So pretty. I think my 17mo would love it. I could also convince DH to Extended RF with this seat for sure!

  147. Love the click tight! And the no rethread harness. They are both fantastic features I can’t decide which I like more lol. Anything that makes it easier for a parent/caregiver to get the installation tight and the child in the seat properly (and easily) is a great thing!

  148. I think the Clicktight installation will make it so much easier to install in my car. This seat would be great for my 4 year old who recently went forward facing.

  149. I love that you can change the harness height without uninstalling. Makes it very easy to change for multiple users!

  150. I’d love to win a frontier 90! I have a feeling my son will be too tall for his convertible soon!

  151. Since I don’t have LATCH in my van, installing seats can be a pain. The ClickTight feature would help me a lot.

  152. I like the click tight feature for sure. But I love the safety and feeling of security that comes along with the Britax name.

  153. My favorite feature is the 90-pound weight capacity using the harness! Would be so great and a true blessing to win!

  154. The clicktight instillation or maybe the easy to adjust harness straps. Hard to pick just one feature.

  155. I love the Click Tight feature and all the up front adjustments (harness height, recline, storing the straps, etc.).

  158. It may be FAA approved now, but I ordered one last week for use on a trip and yesterday the airlines wouldn’t let us use. Both the sticker on side and manual state “not for use in aircraft”. Any idea if Britax can send us new labels? I’m a little frustrated that despite reading it was approved, there’s no way to show the airlines this. Thanks for the indepth review though- very helpful!!

  159. We are currently in a Marathon. Thinking of Frontier 90 for my 3.5 year old who is 40 lbs and 42″ tall. I’m concerned about the latch system weight requirement. How do I find that out? Also, concerned he’s getting too “big” for the Marathon even though he falls within the weight/height requirements. Wondering if Frontier will be safer?
