This car seat is very comfortable, my baby loves it. I recommend it.
Britax - ONE 4 LIFE Clicktight All in One Car Seat
We love this seat so much! It is a bit on the heavier side but that’s fine with us. We ended up ordering another one for my 7 month old who will be transitioning to the bigger car seat soon. I also feel confident installing this seat on my own without my husbands help to make sure it’s tight. 10/10 recommend.
Easy install, my son is very comfortable. We have a Nuna Rava and this is the next best thing for a toddler who has outgrown the Rava.
