Not enough cushion
February 23, 2024
I rate this car seat at 4 stars because the cushion in the back is really thin. I wish it had more thickness to it. It doesn’t feel super comfy for my baby. Other then that is it a super easy to install and move . We use it as a spare car seat so it works great for us.

I purchased this car seat for my grandson, who just turned three. It was affordable, met all safety requirements, and met with my daughter's approval. I also found it easy to test (required two people of course because my grandson weighs a solid 35 pounds), but the buckles and straps held our toddler firmly in the seat when inverted. The install was intuitive and fast, and I had my daughter double-check me (passed her meticulous inspection). My grandson seems quite comfortable in the seat and really enjoys the cup holders, which hold his treasures and his cup. They also come off easily for washing. A great purchase and I highly recommend.

Great buy for the price

I love this car seat. Our grandson can see out of the window now and he loves it. It’s very padded and good for long trips. Easy to adjust and shipping was very fast!

  • Easy to adjust sitting up or laying back. Lot of padding to keep baby comfortable. Easy to adjust head rest up and down for height.
  • Cup holders come out too easily wish it had front anchors.
