Graco Nautilus 2.0 3-in-1 Harness Booster Car Seat, Kara

[This review was collected as part of a promotion.] Installation was very easy. Besides following the instruction manual, there are also helpful installation videos available on YouTube. Overall, the car seat looks safe and comfortable. The fabric feels soft, although my niece tends to sweat easily, so it can get a little warm during the summer. However, with the air conditioning on, it hasn't been a major issue. Since this car seat doesn't have extremely deep side bolsters, I think it may be a better fit for slightly older children who prefer a roomier seat. A couple of things I wish could be improved: the side headrest padding feels a bit firm and doesn't have as much cushioning as I expected. Also, there are only two crotch buckle positions. Having one additional position would provide more flexibility. My 5-year-old niece is already using the outermost slot, and when she wears a fluffy dress, the buckle area can feel quite snug. She has occasionally mentioned that it feels a little tight and uncomfortable. That said, for this price point, I really appreciate that this is a 3-in-1 car seat with a steel-reinforced frame. The overall safety design gives me peace of mind, and I feel confident keep using it.
