Most Helpful Reviews on the Safety 1st onBoard 35 Air Infant Car Seat.

  • 5.0 out of 5 stars(5/5) – 2/16/2012 – … I found this carseat and could have KICKED myself for not buying it in the first place!! It would have easily fit my preemie daughter when she was born, it adjusts VERY easily and is NOT bulky or heavy – even though it holds up to a 35 pound baby! It is SO comfortable too! The padding isn’t bulky, yet is amazingly soft and feels like a little pillow top bed ;)… OH I forgot to mention one of my favorite features – it has a compartment inside to help you Keep your seatbelt tight – unlike those annoying “locking clips” all you do is pull the carseat strap through it shut the compartment and it stays tight! It also has the perfect seat indicator button…so you know your seat is perfectly level in your car!… (read more and buy it at
  • 5.0 out of 5 stars(5/5) – 8/18/2012 – My husband used to be a car safety engineer. His team crashed cars & shot dummy heads inside vehicles all day long to test crash impact at different speeds, & they designed the impact foam structures in car interiors. So he did some intensive research on infant car seats for our baby…. We promptly stripped the car seat to inspect the foam/padding…. Basically, under all the different covers/different brand car seats, lies the same thing…. I’ve read a few moms’ complaints about having to use 2 hands to release this car seat from the backseat. I found if you tilt the car seat toward the same direction of the latch while pressing it, then it will come out effortlessly without waking the baby…. Also, some other reviews complained about the canopy being flimsy…. I also have to agree with other reviews on the cover pilling…. (read more and buy it at
  • 4.0 out of 5 stars(4/5) – 11/7/2011 – Overall, this product was everything I expected. You cannot beat the price. My 2 problems were 1) The seat is not very cushioned. I would have hoped for a softer seat, especially for an infant, and 2) The canopy is really flimsy….  (read more and buy it at
  • 5.0 out of 5 stars(5/5) – 1/14/2011 – We love this Car Seat mostly because it will grow with our baby. I had a premature baby and she fit perfectly in this seat at 5 lbs and I am so happy that it will grow with her up to 35 lbs. The only thing I have found that I don’t like is that I feel like it doesn’t click in very easily. I have to shake it back and forth once I set it in to make sure it is in, and if my baby is sleeping when I put her in…she isn’t after I shake her!  (read more and buy it at
  • 2.0 out of 5 stars(2/5) – 11/7/2010 – To start off with the car seat is too much of a 90 degree angle so the baby can’t relax comfortably in it. The material is too thin and the head protector really doesn’t do anything but get in the way…. (read more and buy it at
  • 5.0 out of 5 stars(5/5) – 4/20/2012 – There are so many options these days when it comes to car seats so you want to make sure you research and find a car seat that will work for your family and baby! Safety 1st helps you to start your little one off on the right road with the onBoard 35 Air Infant Car Seat featuring Air Protect Side Impact Technology…. From the small chest clip, to the specifically newborn designed angle ball (the lower 45 degree angle helps smaller babies whose heads still flop forward prevent airway obstruction) , to the customizable insert and low harness slots this seat is perfect for big and tiny babies alike!The latch base is also very easy to use. There is a foot that allows you to adjust the recline angle. It is super easy to increase or decrease the height you need…Disclaimer- I received this seat free of charge to review it and share my opinions…. (read more and buy it at
