The Britax is deep and makes my baby slouch, but he sits nice and comfortably in this car seat. Less than a year old. would consider a different company. The installation is amazingly easy and I love that the base has 5-position adjustment to help level the car seat. One down side is the car seat doesn’t attach well to strollers that are not safety 1st. The installations and functions all work the same, but Safety 1st is easier to carry around. “The car seat was just as described, it was just like the picture, and I totally loved it! I was surprised at how much lighter it is than the Graco seat I use in my car.
