size-mattersIs your vehicle’s front-to-back space limited? Are you and/or your partner tall or just leggy? Or maybe you just want the ability to stretch out a little bit more on a long ride. Regardless of why you need more leg room up front, the reality is that you’re not alone. The rear-facing carseat/space issue comes up over and over again here at CarseatBlog, on our blog’s Facebook page and on the Car-Seat.org forums. Everyone, it seems, is looking for a good quality, higher-weight-harness convertible that will keep their child happy and comfortably seated in the rear-facing position while still allowing the front seat driver and/or passenger to be safe and comfortable too. Because let’s face it, you shouldn’t have to sacrifice your comfort or safety just to accommodate junior who is optimally seated rear-facing in a convertible behind you!

Additionally, as a mom and a Child Passenger Safety Technician-Instructor, I know that space factors play an important role for many parents in their decision on when to make that “demotion” in safety from rear-facing to forward-facing.  Ideally that switch from RF to FF shouldn’t occur until the child has maxed out their convertible seat by either height or weight, but that’s rarely the reality. The reality is that the vast majority of parents in this country are still turning their toddlers forward-facing before the recommended minimum age of 2 and, in most cases, way before the RF weight or height limits of their convertible seat are actually reached. I know space issues play a role in many of those decisions. Hopefully this blog can help by giving parents some useful info on which  rear-facing convertibles take up the least amount of room.

I must stress that every vehicle is different and our measurements may not translate exactly to your vehicle. For example, if you are installing in a center seating position or have a larger vehicle, you may have plenty of room – even for the space hogs. Since there are too many variables from vehicle to vehicle and even from one seating position to the next (within the same vehicle), I can’t and won’t tell you that seat X or seat Y is going to be the best choice for your child in your vehicle. But I can tell you that seat X takes up 3″ less room when rear-facing than seat Y when installed properly and in accordance with the manufacturer’s directions in the same seating position. The rest of the factors (specs, features, price, etc.) are going to be up to you to take into account. Because even though size matters, it’s not the only thing that matters!

With that in mind, I chose convertibles that are either on our list of Recommended Seats or just popular higher-weight convertibles. I did not include small convertible seats like the Combi Coccoro, because I know that most of our readers are looking for convertibles that can last for several years and can be used for extended rear-facing. The Coccoro is a great little seat that doesn’t take up much room when rear-facing and is fairly narrow, too. That’s a huge bonus in compact cars. The trade-off is that it’s hardly bigger than some of the infant seats currently on the market so it’s quickly outgrown by height and weight in the RF position. Average size models, like the Britax G4 convertibles and Peg Perego Primo Viaggio Convertible, have modest rear-facing height limits but can still accommodate many kids rear-facing past 24 months old AND fit easily in your small car!

While this list does include 18 current convertible models, it is NOT an all-inclusive list and I was limited to what I had available or had access to during the project period.  More models may be added in the future.

grade-b-plusSeats have been given letter grades for simplicity. This “Space Grade” relates only to the amount of room that the seat takes up when rear-facing as compared with the other seats on this list.  Keep in mind that even seats with an “A” rating aren’t guaranteed to fit rear-facing or install properly in the back seat of your vehicle but they’re a good place to start if you’re on a quest to find a good rear-facing convertible that doesn’t take up a lot of room. By the same token, just because a seat has a “C” or “D” rating doesn’t mean it won’t fit well rear-facing in a smaller vehicle. There are just so many variables in each specific situation that you really never know for sure until you try it.

For the record, my installation method for each seat was pretty basic. I didn’t use any tricks to try to get the seats more upright or anything like that. I also didn’t attach the rear-facing tether in cases where that was specifically an option (Britax, Diono). I used the lower LATCH anchors for each install just to be consistent, and because it was easier in most cases. Each seat was installed properly and in accordance with the manufacturer’s instructions. In most cases I didn’t need to any pool noodles to increase the recline angle because it wasn’t necessary – but there were a few exceptions. Normally, I like to get behind the rear-facing convertible and use my hips or mid-section to compress the seat down and into the vehicle seat cushion, leaving both hands free to tighten the seatbelt or latch strap. However, I couldn’t do that with these installs because that would have required moving the front seat forward to get my body back there, and that wasn’t an option. The front passenger seat stayed in its precise position throughout the project period.

I set the front passenger’s seat in a specific fixed position with the seatback angle neither too reclined nor too upright for an adult to sit comfortably. Then, in each case I measured the distance between the convertible and the point on the back of the front passenger seat or head restraint that was likely to make first contact. That “contact point” varied depending on the height and contour of the CR. So, this means that these measurements and grades could vary somewhat in a different vehicle that has a different contour of vehicle seats, different geometry of head restraints or is simply installed somewhat differently.  In other words… 

Your mileage may vary!

In cases where the convertible had a height-adjustable headrest (HR), I took separate measurements with the HR flush with the shell and also with the HR extended to the max RF height limit. If the convertible allowed more than one recline position to be used for RF then I installed the seat using the different recline positions as long as it installed within the acceptable recline angle range. There was one exception I made and that was for the Maxi-Cosi Pria 70 installed in the semi-reclined position. I was just so blown away by the amount of room that I gained with that seat in the #2 recline position that I couldn’t throw it out just because the level line wasn’t level with the ground. More specific details on that installation and those results can be found in the Maxi-Cosi Pria 70 notes below.

Okay, enough rambling… this is what you’re here for! Below is a table comparing the various convertibles and listing their space grade, the amount of space gained in relation to the most space-consuming convertibles tested and the seat’s RF weight and seated height limits. *Hint: if you’re viewing this on your phone – turn it sideways to see all 4 columns.

Space Grade” is not our rating of the carseat overall. It is an indicator of how much extra space it offered the front seat passenger in our test vehicle.

Britax Pavilion G4 is equivalent in size to Britax Marathon G4Boulevard G4 and Advocate G4

** Diono Rainier is equivalent in size to Diono Pacifica and Diono Olympia

*** Graco Size4Me is equivalent in size to the Graco HeadWise, Graco MySize and Graco Fit4Me

Note: CR Interior Height Measurement refers to the measurement of the Child Restraint (CR) from the bottom of the seated area to the top of the restraint in its maximum rear-facing height position (picture below).  This measurement may range from 23″ to 28″.  The overall “Child Height”, or standing height limit is also stated for seats that list one in their owner’s manual. The “1 Inch Rule” states that the child has outgrown the CR by height if there is only 1″ of shell or headwing structure (this varies from seat to seat so check the notes in the chart above) left above the child’s head. In other words, you always want more than 1″ of shell or structure above your child’s head. Once they get to the point where there is only 1″ left above their head – the seat is outgrown in the rear-facing position.

Maxi-Cosi Pria 70 (without TinyFit)

Specs:  RF 9-40 lbs; RF height limit is child height 40″ and top of head below top of headrest; RF max seated height 25″ tall; FF 22-70 lbs or up to 52″ tall.

Space Grade:  A+ (when installed in semi-recline position #2 with headrest fully extended)*

Space Gained +7.5″

Space Grade:  B (when installed in full recline position #3; headrest fully extended)

Space Gained +3.5″

Notes:  Recline position #3 (full recline) or #2 (semi-reclined) may be used to achieve an appropriate RF recline angle as per the level-to-ground-line angle indicator. These options create more potential for finding a suitable recline angle and taking up less space. Recline may be increased, if necessary, by using a pool noodle or tightly rolled towel under base. *When CR was installed in semi-recline #2 position in my vehicle, the level line was NOT quite level to ground (see pics below) and the seat was very upright. Since the level line on this CR is just a line on the side of the shell and there isn’t an allowable angle range for RF, the angle achieved will vary based on the slope of your vehicle’s seat cushion. The recline angle achieved using the #2 position was similar to how the Radian installed with the angle adjuster in this seating position. Technically, it isn’t a correct installation because the level line isn’t level to the ground. However, with a whopping +7.5″ of RF space gained, perhaps this could fall under the “parental decision” category if you had an older RF child who preferred to sit very upright? Full Maxi-Cosi Pria 70 Review Here.

Specs:  RF 5-45 lbs; RF height limit 1″ rule from top of adjustable headrest when extended to 7th height setting; RF max seated height 24″ tall; FF 22-70 lbs or up to 49″ tall.

Space Grade:  A (when installed with headrest flush with shell)

Space Gained +5″

Space Grade:  A- (when installed with headrest extended to max RF height setting)

Space Gained +4.5″

Notes:  Only 1 base position allowed for rear-facing installation. Headrest height positions 1-7 may be used for RF. Positions 8, 9 & 10 are FF only. Recline may be increased, if necessary, by using a pool noodle or tightly rolled towel under base. Full Peg Perego Primo Viaggio Convertible Review Here.

Safety 1st Advance SE 65 Air +

Specs:  RF 5-40 lbs.; RF height limit is child height 40″; RF seated height 28″ tall; FF 22-65 lbs. or up to 52″ tall

Space Grade:  C  (when installed at most upright angle allowed for children over 22 lbs.)

Space Gained +2″

Space Grade:  D  (when installed at max recline angle for babies under 22 lbs.)

Space Gained +.5″

Notes:  This carseat has a dual level-line indicator for rear-facing. Recline positions 1, 2 or 3 may be used for rear-facing to achieve the appropriate recline angle as per the line indicator on the sticker label. Even with the base in recline position #1 (most reclined) I still needed to add a pool noodle to achieve the necessary recline angle for a baby under 22 lbs. Children over 22 lbs. who can sit upright unassisted may have the seat positioned more upright as long as the angle is still within the dual line indicator.

Space Grade:  D

Space Gained +.5″

Notes:  This carseat has a dual level-line indicator for rear-facing. Single recline position for rear-facing installations. Seat was installed with more upright line level to ground. This angle is allowed for child over 22 lbs. who can sit upright unassisted. If I needed to install the seat at a more reclined angle for a child weighing less than 22 lbs. then it would have taken up a ridiculous amount of room, even in my minivan. Even at the max upright angle this seat is a space hog and would have required the use of noodles or a tightly rolled towel to achieve the appropriate recline (this was the basic Complete Air model and lacked the adjustable base found on the LX model). Since I was installing just for the sake of measuring, I took the lazy way out and just wedged the edge of the carseat into the vehicle seat cushion and it stayed tight. Full Review of the Safety 1st Complete Air Here.

Space Gained +3.5″

Notes:  Single recline position for rear-facing installations. This carseat has a dual level-line indicator for rear-facing. Babies under 22 lbs. should be positioned at the max recline angle. Children over 22 lbs. who can sit upright unassisted may have the seat positioned more upright as long as the angle is still within the dual line indicator. Even at the most upright angle this seat would have required the use of a pool noodle or thin rolled up towel to achieve an appropriate recline. Several noodles would have been necessary to achieve the maximum reclined needed for babies under 22 lbs.

Conclusion:

There are so many variables that go into every carseat/vehicle compatibility scenario that it’s impossible to accurately predict which seat is going to be the “best” convertible for rear-facing *your* child in *your* vehicle. The complexity of the situation is amplified by the plethora of options and features available on various convertibles. Still, it was our intention here at CarseatBlog to put together a comprehensive comparison that would serve as a resource for parents and caregivers searching for an extended-use convertible that would keep their rear-facing toddler or older child safe and comfortable without sacrificing the safety and comfort of the driver and/or front seat passenger.

As always, the best advice for any carseat purchase is to “try before you buy”. However, in cases where that isn’t possible then the next best thing is to order from someplace with easy, free returns in case it doesn’t work out.  For example, Amazon offers a wide selection of carseats at competitive prices and they offer free shipping AND free returns on all seats that they sell directly.

We hope this info was helpful to you! It was an exhausting but enlightening process for me too!  You should also check out our all-inclusive list of Rear-Facing Convertible Measurements, Height Limits & Weight Limits.
