Three position adjustable crotch strap (5″, 6″, 7″) allows a wide variety of children to fit the Pria without being uncomfortable.  It must be in the smallest and middle position when rear facing without the Tiny Fit.  When using the Tiny Fit insert, the buckle must be in the furthest out position.  Forward facing it can be in any position.

Three adjustable recline settings allow you to be able to adjust the seat to the correct recline depending on your seat slope and child’s weight.  When rear facing the recline position must be at angle 2 or 3.  Forward facing for children from 22-40 it must be at angle 2 and forward facing children from 40-70 lbs must be at angle 1.

Push button lower anchor connectors help with those deeply buried vehicle lower anchors and makes for an easier install and uninstall.

The no re-thread harness is adjusted by just the squeeze of a button at the top of the head support.  It is a nice addition so you don’t have to move the harness straps manually.

TinyFit infant insert –   This insert is like a seat within a seat.  It does take some extra effort to install into the seat due to this.  The TinyFit fits infants from 4-22 lbs and must be used until the infant’s shoulders reach the bottom harness position without the insert (10″).

TinyFit body pillow is a welcome addition for those little infants that need a bit of extra side to side support when using the TinyFit infant insert.

The Head pillow can be used to help support a newborn’s head.

TinyFit Insert Installation

The TinyFit Insert is a seat within a seat.  It is a plastic insert that is actually installed into the seat for small infants.  This takes the hassle out of using a rear facing only seat for a newborn and allows a parent/caregiver to use the Maxi-Cosi Pria 70 from birth.
The installation can be a bit time consuming so here’s a quick run down of how it works.

 

1.  Make sure the crotch buckle is in the furthest out from the back position.

2. Unthread the harness from the back of the car seat and pull everything except the buckles off, if you will be replacing the large chest clip for the smaller one.  If not, it can all be left on, but can be a hassle to get through the holes in the insert.

3.  Set the insert on the seat and thread the harness and buckles through the holes at the bottom of the insert.  Thread the chest clip, harness comfort pads, and head pillow onto the harness, then thread the harness through the appropriate harness slot in the insert.

When installing with the TinyFit insert, the crotch buckle needs to be in the furthest out from the back position and the lower anchor strap or seat belt is routed behind the buckle.  Make sure the head support is fully extended so you can push the insert up a bit in order to route the lower anchor strap or seatbelt under it.

When installing without the TinyFit the crotch buckle needs to be in either the smallest or middle crotch buckle position then the lower anchor strap or seat belt is threaded in front of the buckle.

Like other Maxi-Cosi convertibles the Pria 70 also incorporates a belt positioning guide on either side of the rear facing belt path.  The lower anchor strap or lap portion of the seat belt needs to be threaded through this before tightening.

Maxi-Cosi also incorporates the use of a single level-to-ground line to judge what angle the seat needs to be at when rear facing.  This line is a raised portion of plastic at the top of the seat right above a green sticker.  When installing rear facing the angle can be adjusted to either position two or three.  I noticed that it installs pretty upright with the level-to-ground line.  This is nice for both front to back space and for older children who would like to be more upright.  The TinyFit insert reclines smaller infants more so there isn’t head slump.

Forward Facing Installation

The forward facing install is very typical.  The lower anchor strap or seat belt needs to be threaded through the forward facing belt path.  Make sure to lock the belt if installing with that method.  Then put yours weight into the seat and tighten.  Needs to be 1″ or less of movement at the belt path.  The only thing that is a bit different is that for children from 22-40 lbs and 29-43″ it needs to be in recline position 2 and for children 40-70 lbs and 43-52″ it needs to be in position 1.  As a forewarning, there will most likely be a decent gap between the seat bight and car seat.  This has been okayed by the manufacturer as long as you still have a tight (1″ or less of movement at the belt path) installation.  Also, the larger harness pads need to be used for children over 65 lbs if the seating position is without a vehicle tether anchor.

 

 

 

 

Fit to Child

Rear Facing with TinyFit insert

  • Rear facing weight range: TinyFit 4-22 lbs
  • Rear facing height range: 40″ or less
  • Lowest harness position: TinyFit 5″

Maxi-Cosi Pria 70 with TinyFit: Jo – Preemie, 4 lbs, 17″

Jo – Preemie Huggable Images doll, 4 lbs, 17″
The TinyFit insert was a perfect fit for her!  I used the head pillow, body support, and small chest clip.  All helped with fit tremendously.  The TinyFit adjusts the lowest harness height down to 5″, one of the shortest harness positions on the market.  Her shoulders were actually quite a bit above the lowest harness position, almost up to the 2nd harness position, which is very rare for Jo.  The biggest downfall I had with using the TinyFit with her was tightening the harness straps.  Due to the extra routing through both the TinyFit insert and seat shell it adds quite a bit of friction making it harder to tighten.  It would be necessary to tighten from the back of the seat typically by pulling the harness straps from the back of the seat, then pulling on the tightening strap tail by the child’s feet.

Fiona had an amazing fit as well.  I kept all the inserts and smaller chest clip on for her and she had a very similar fit to Jo.  With her being just a tad taller in the torso than Jo, she was a bit closer to the 2nd harness slot, but still not quite there.  I also had the same tightening issues as I did with Jo.

Maxi-Cosi Pria 70 with TinyFit: Anders - 8 months, 20 lbs, 26"

Maxi-Cosi Pria 70 with TinyFit: Anders – 8 months, 20 lbs, 26″

 

 

Anders – 8 months, 20 lbs, 26″
He fits, but was extremely uncomfortable and had very little excess harness length.  At his size and fit, I wouldn’t use the TinyFit insert for him normally since his shoulders come right above the bottom harness position without the TinyFit insert.  Even though the insert is approved for use up to 22 lbs, I think 15 lbs would probably be a better limit for it.

 

Rear facing without TinyFit insert

  • Rear facing weight range: without TinyFit 9-40 lbs
  • Rear facing height range: 40″ or less or top of the head at the top of the fully extended head support
  • Lowest harness position: without TinyFit 10″
Maxi-Cosi Pria 70 with TinyFit: Anders - 12 months, 23 lbs, 29"

Maxi-Cosi Pria 70 with TinyFit: Anders – 12 months, 23 lbs, 29″

Anders – 12 months, 23 lbs, 29″

Anders fits perfectly without the TinyFit insert now.  His shoulders are still just barely below the 2nd harness position, so he is still in the first.  Even without the TinyFit insert, the harness is still pretty difficult to tighten, so we just keep doing the tightening trick I mentioned with the TinyFit.

Maxi-Cosi Pria 70 with TinyFit: Freya - 1 month shy of 3 yrs, 25 lbs, 33"

Freya also fits perfectly in this seat with quite a bit of growing room still.  Like Anders, she loves how upright she sits in it.  It has decently low sides, so I don’t have to hoist her too much over the sides.  Although the base is rather high, so it sits quite a ways above the vehicle seat.

 

 

Forward Facing

  • Forward facing weight range: 22-70 lbs
  • Forward facing height range: 29-43″
  • Shell height: 26.5″ (top of fully extended head support)

Freya – 1 month shy of 3 yrs, 25 lbs, 33″

Freya doesn’t ride this way, but is within the limits of it forward facing.  We recommend rear facing until as close to 4 as possible.  This is just a model of how a smaller child would look forward facing in it.  Since she is between 22-40 lbs it is on recline position 2.  I like how reclined it is for her.  It would be a good choice for a smaller forward facing child due to this.  It was near impossible to tighten the harness forward facing.  I would most likely tighten it before installing, then not loosen it, unless necessary.

Maxi-Cosi Pria 70 with TinyFit: Chloe - 6 yrs, 46 lbs, 48"

Maxi-Cosi Pria 70 with TinyFit: Chloe – 6 yrs, 46 lbs, 48″

 

 

Chloe – 6 year Huggable Images doll, 46 lbs, 48″

Chloe is right at the limit of the Pria 70.  Her shoulders are right at the top harness position.  Her head seems a bit squished in between the air protect SIP.  She had very little harness length left as well.  I don’t foresee the Pria 70 fitting any 70 lb children.

    Overall Thoughts

    Overall I’ve been very impressed with the Maxi-Cosi Pria 70 with TinyFit.  The TinyFit fits newborns well thus taking away the need to buy and use a rear facing only seat to start with.  The 22 lbs limit on the TinyFit is a bit overinflated and I would foresee most children closer to at least 15 lbs being ready for the seat without the TinyFit insert.  The 70 lbs may be a bit overinflated as well as most children that size will have already outgrown the top harness slot and be uncomfortable with the tight head support.  The head support can also be a bit of a hassle to adjust fully down or up.  You typically have to push it from the back of the seat.  The last downfall is the difficulty in tightening the harness.  Maxi-Cosi has stated that they will be releasing new seats with an adjusted harness system to solve this issue.  The updates they’ve made to the newer models are also a very nice addition.  I love how small the Maxi-Cosi Pria 70 is in my van and the cushy fabric is great.  Both my kids regularly sleep in this seat when we’re out and about.  Installation is a breeze and the cupholder is a nice bonus for storing all the little kid trinkets.
