Great narrow seat!

 from Riverside, CA– Verified Buyer

Just as other reviewers have said, this is perfect for fitting 3 across in your car/SUV. It is more comfortable for my kiddos than I thought it would be- he naps comfortably in it :)

Really Nice!

 from Virginia– Verified Buyer

This is a great car seat. We have bought these in the past and have loved every one. Good quality and fit just great. Very secure and safe for the baby.

Was this helpful? Yes / No

My daughter loves it

 from Hawley, PA– Verified Buyer

I chose this car seat after much research and much debate. We have an earlier version of this seat, but my daughter prefers this seat much more. The seat is cushioned and comfortable. I really like the high head support. When she naps, her head does not flop back and forth.
The reason I gave a 4 was because I ordered the seat in April and it was not delivered until June.

Was this helpful? Yes / No

Love this car seat!

 from Victorville, CA– Verified Buyer

I chose this car seat because there is no flame retardants in the fabric. I love how comfy my babies look in this car seat! I felt very safe traveling with them across the country in these car seats.
