Excited to bring my baby boy home in this. Definitely recommend! Review: Silla de auto segura, cómoda y fácil de instalar / Safe, comfortable, and easy-to-install car seat - bought this car seat for my baby, and so far it has been a great choice. It feels sturdy and well-built, which gives me peace of mind when using it in the car. Installation was quite simple by following the instructions. I like that it stays firm and secure once installed. The design is very practical, and the handle makes it easy to carry the baby without waking them up. In terms of comfort, the padding is soft and seems to keep my baby comfortable during trips. I also like the canopy, which helps protect from the sun when outside. As a small downside, it could be a bit lighter, but overall it does its job very well. In summary, it’s an excellent option if you’re looking for a safe, comfortable, and easy-to-use car seat for your baby. I recommend it for parents who want something practical and reliable. ## Features - EASY FOR PARENTS, A COMFY, SECURE RIDE FOR LITTLES The onBoard FLX Infant Car Seat fits little ones 4–30 lbs. rear-facing and up to 32".
