Fits 3 in Subaru Outback!
The look of this car seat is great. It’s got loads of padding, very sleek. Looks comfortable for my big toddler as well as my petite toddler. Needed to buy these to fit 3 across in my Subaru Outback. Easy to install, look durable. We’ve had them for more than 6 months and they hold up well. I feel that my kids are safe and well supported all while fulfilling the need to be slim in order to have 3 across by backseat. Right now we have 2 installed but already purchased the 3rd one for our newest baby. Would highly recommend.

Safety
I’ll give it 5 stars for safety but it’s very hard to get the baby buckled in because straps are short and can’t be lengthened or let out. My baby is 2 and as she grows I’ll probably have to buy another car seat because of the length of harness straps.

Britax is the BESTTTT
Britax remains my top choice for my kids' car seats. Easiest seat to install, feels the safest once it's in place, and it's super comfortable for my kids. Signed, seasoned mom of 3!

Overall great
Overall, i love this car seat. it’s strong and sturdy. my only complaints are that, if snacks fall in the checkered area, they’re almost impossible to get out. Also, we went on a 7 hour drive with plenty of stops and my 2 year old was complaining her butt hurt. Other than that, it’s great and i know she’s safe!
