    Comments about OnBoard 35 Air Infant Car Seat- Silverleaf:

    I LOVE this car seat but, more importantly, my four month old loves this car seat. He started out in the Peg Perego Primo Viaggo but grew out of it within a few weeks (he is extremely tall for his age). Also, I hated lifting the Peg Perego in and out of the car. It was soooo heavy. But when I realized there was no way my son would last in it, I knew I didn't want to compromise his safety. This "Air" feature on this car seat gives me peace of mind. Peg Perego, in fact, has a similar feature. I also like that the recline on this car seat is a lot greater than Peg Perego's, which is a tad to upright. When I put my baby in the Onboard Air, I feel like I'm sitting him on a throne - thats how comfy it looks. And no more screaming everytime I put him in!
