Review: Great company great chair - So far I'm loving this chair. It's soft and cozy for my babe. Easy snap and unsnap. Keeps the head in good position even when slumped over, the straps are covered with a good cushion. Great value for the money for sure. Surprisingly not as heavy as some chairs, so much so that I could lift and install by myself (I'm 4'10" and petite). Doesn't take up too much space in the back seat. I feel very comfortable and confident with it. *update almost a year later. This seat is amazing. We flew with it and it fit in the car seat bag easily for free plane drop at gate. Husband said it was lighter than the one in his truck that we used on previous trips (Graco). It was super easy to strap with a seatbelt in the middle of winter at the airport pickup line. Yes using a rolled towel is standard procedure to fill any gap between the car's seat and the car seat itself, some cars have deeper bucket seats and that's why. It doesn't eat into son's legs because the padding is there for exactly that. Cleaning is easy with a warm sudsy water and a cloth, not a brush (bad for the fibers of the seatbelts) and air dry. I took off the snack attachment from the cup holder for more storage rather than snacks. No food when driving, cause I'm afraid of him chocking when I can't help, plus it helps with the mess. He reaches the water easily if it has handles, like the blue cup I have in the picture. 10/10 still to this day
Review: Good quality. Highly satisfied - I have 3 of this same car seat and I definitely cannot complain about quality and comfort. My son out grew his infant bucket seat pretty fast and we needed another car seat and. I like all of th padding and the fact that the it's separate pieces so your able to remove them with no problem. Changing the positions of the straps is very easy too. The only downfall that I will say is the strap that goes across the back of it to hook to the clamps in the seats is not very long and hard to tighten which makes it difficult to strap down. Once carseat is installed it's very sturdy, safe and doesn't take up much room. I drive a 2022 Hyundai Tucson and it fits great in the backseat. Do not have to adjust the front seats to make you feel like your sitting in the dash front facing or rear facing.
