I bought this car seat back in 2021 and it’s been amazing. My son absolutely loves it says it’s super comfy and loves the cup holders. I love the pattern on my seat I think it’s the Matrix pattern sad to see they don’t make it anymore. The installation is super easy I always used the seatbelt install and always get a super firm install. It’s a little bulky as it is a convertible car seat. Overall Jackleb992 · Graco
