Jané Montecarlo R1 Review

For those who have been around the car seat world long enough, Jané is a familiar name. In 2003, Jané brought boosters with lower anchor capability to the US. Jané has been quiet for a while in the car seat world though, in the US anyways. They introduced the Montecarlo R1 to their European market and just now brought it here to the US. Let’s see what this new seat has to offer.

The Montecarlo R1 comes out of the box preassembled. The Flame color is beautiful; much prettier than the pictures online show. Yale or Klein are also available color choices. All are very mature colors for older kids; which is nice. The cover on the Montecarlo R1 is nicely padded and would be a good choice for even the most discerning booster users. The cover is also easily removed for cleaning and is held on to the booster with a series of snaps built on to the seat and velcro straps around the head support. The snaps have unsnapped a few times on the bottom front from regular use, but they’re super easy to resnap. The cover is made from a soft polyester blend that is meant to breathe in the summer and help retain heat in the winter. There are vent holes all along the back of the seat and on the side bolsters to help with breathability. Not something you see in most boosters.

The storage spot for the manual on the Montecarlo R1 is very clearly marked so there are no excuses to not read it! Manage to lose it even with a specially marked spot? No worries. There is a handy QR code on the side of the seat that takes you to the manual online.

While going through the manual it was discovered that the age limit was listed as approximately 1.5-12 years old for the Montecarlo R1.

Yay on the 12! Our booster seat science post goes over all the whys of using a booster that long. On the flip side, a child should be rear facing until two to four years old and should not be in a booster until at least five. Our harness or booster post goes over what to look for when thinking about switching to a booster.



Jane Montecarlo R1 using rigid lower anchor connectors

If you’ve never used rigid lower anchor connectors, you’ll love them on the Montecarlo R1. It is unknown if having them on boosters add any safety benefit, but they are great for those kids who forget to buckle the seat belt over the booster when they get out of the vehicle. Unoccupied boosters can be a projectile in the vehicle like anything else that is loose; lower anchor connectors fix that. Rigid connectors make it that much easier for caregiver to use over the traditional ones. The Montecarlo R1 does come with covers on the connectors to protect them (and the vehicle) if they are not in use. Remove those, slide out the lower connectors, attach to anchor bars, and push booster into the seat. The sliding out of the lower anchors is not an easy task. Having it done it a few times now, the buttons have loosened up some making it easier, but it’s something you’ll need to read the manual for as it’s not necessarily self-explanatory.

Jane Montecarlo R1 unique features

Another feature of the Montecarlo R1 is the aluminum integrated into the back support and head support. It gives it structure while still keeping it lightweight. The head support has five positions to fit a variety of children. When positioned correctly, the belt guide needs to be as close to even with the shoulder as possible, but never below. It also has three position adjustable arm rests. Having it in the highest position seems to help make buckling a little easier. The Montecarlo R1 also features a mechanical recline position, which can only be engaged without the child in the seat, so you must adjust prior to the child climbing in. There didn’t seem to be a big difference between the positions but it might be nice if you know you’ll be going on a longer trip and you tend to have a noodle kid when they fall asleep. The torso and head support should do a good job at keeping most kids positioned well though.


The biggest feature of the Montecarlo R1 is the fully adjustable torso and head support; both are lined with energy absorbing foam. This foam is meant to absorb some of the energy from the crash meaning less crash forces are transferred to the child. There are two knobs on the side of the seat, one makes the torso support adjust wider and more narrow and one controls the head support. This makes it a great seat for children of all sizes and can customize the fit to them. Even fully open, this booster is more suited to children with a narrower frame. Also, the torso knob sticks out an odd angle in vehicles with side bolsters. You can see how above it is running into the side of a captain’s chair. This has made the knob loose and hard to use when the seat is installed in this vehicle. If you recline the vehicle seat, you will have better access to the knob. Be sure to put the seat back upright again before moving the vehicle.

Jane Montecarlo R1- Olivia, 5.5 years, 50 lbs., 46 inches


This is Olivia showing off the most narrow and the most open head support positions. She’s just over 5.5 years old and right at 50 lbs. and 46″. Her favorite feature was the adjustable head wings. She liked them tight on her head to ‘squish’ her. She fit great in the seat and was on the fourth position (barely) of five with some growing room before she’d need the highest position.



Jane Montecarlo R1- Addison, 6.5 years, 41 lbs., 45 inches

This is Addison, she’s 6.5 years old, 41 lbs. and 45″. She is right on the cusp of being too tall for the bottom position, so the second seems to fit her a little bit better. She had great leg support even though she has such long legs for her height. You can see how torso height can change the length of time a booster can be used when you compare her to Olivia above. Olivia is only 1″ taller but needs the fourth guide position.




Jane Montecarlo R1- Ilana, almost 8 years, 67 lbs., 49.75 inches

Ilana will be 8 in less than a month and still uses a high back booster. She’s 67 lbs. and 49.75″ and using the highest belt guide position with little growing room. You can see it’s a bit shallow for her and I feel kind of pushes her forward. She didn’t complain though and seemed to find it comfortable and chose to use it over her regular booster when given the chance. She did mention she felt a bit squished in the shoulder and arm region because of the torso support but at the same time found it cozy. Eight year old girls might not be the best source of solid information. Unfortunately she has little room left height wise anyways and it does not become a no back booster.



Jane Montecarlo R1- Evan, 9.75 years, 63 lbs., 51 inches



Evan will be 10 in less than two months and still uses a high back booster as well most of the time. He’s 63 lbs. and 51″ and is also using the highest belt guide position. His torso isn’t quite as long so he has a little bit more room to grow than his younger sister. He liked being able to adjust the head wings himself and he too likes the seat to ‘squish’ his head. Silly kids! Again, it’s rather shallow for his legs but with more narrow build, it doesn’t seem as noticeable. He’s also not feeling as tight in the torso area because of his narrow build.


Finding more seats that work for three across is always a fun time (maybe not that fun). With five kids, all in some kind of seat, it’s like a game! The Montecarlo R1 was tried in the back of the Town and Country with an Evenflo Sureride and Harmony Folding booster. With its narrow frame (when the torso protection is adjusted inward) and adjustable arm rests, we might have a winner. Sort of. It fit nicely and could get buckled, but because of the head wings it could only get to position four of the five settings which meant it did not work for either of the older kids back there. If it were next to a rear facing seat, you would have more flexibility in the torso protection position.

Jane Montecarlo R1 lower anchor guides



A feature of the Montecarlo R1 that was unnecessary in the Town and Country, were the lower anchor attachment guides. The lower anchors are right there, plain sight, you won’t miss them. Some parents have vehicles where the lower anchors were almost dismissed completely and just went to seat belt because they were so hard to access. That’s where these little guys can come in handy. Simply attach them to your lower anchors and it helps guide the rigid connectors onto the bars. Releasing the connectors isn’t a concern, it’s just getting them attached in some vehicles that can be tricky.


Overall the kids give the Montecarlo R1 a thumbs up with it probably being most suited to the younger booster user we tried. It really became well liked as it was used more in the Town and Country. They loved the head wings and the cover was really nice and soft, much more than our other seats. The lower anchors make it easy to install and keep in place when unoccupied and it also seems it would work in a three across situation. It also kept the booster in place nicely. We tried it in an older Cavalier and it was a bit tippy for the newest of the booster riders. She had a hard time keeping upright, but it would probably be fine for an older, more experienced rider. For the price point though, it could be a little deeper and the head support could adjust higher as it does not become a backless booster. The Montecarlo R1 should get most children to around 8 years old, but as kids need boosters for 3-4 years after that, it’s disappointing it would be outgrown so soon. Now if you have a petite child like Evan above, or a smaller torsoed child like Addison, the price may work out better in the end. It also doesn’t have a cup holder. Not a big deal as most cup holders on boosters don’t do a good job at holding drinks, but kids like having a little place to put things when in the vehicle.
