Comfortable and Built to Grow

Great all-in-one car seat! Very sturdy, comfortable, and easy to install. I love that it grows with my child and the ClearTex fabric gives peace of mind with no added chemicals. Well-designed and convenient for my child in forward facing with different positions for sleeping and eating. Definitely worth the price. Highly recommend!

Luxury for my grandson

Purchased this car seat for my grandson. We have the Chicco jogging stroller and all in one infant seat also. Love the safety, stability and protection that this car seat provides compared to others. He still rides backwards and this seat provides a very comfortable rear facing position. The fabric is luxury smooth and easy to wipe clean. He is currently 15 lbs. at 6 mos, but was born 5 lbs 5 ozs, so I was very particular about the seat I chose for him. The other seats I looked at just didn’t have the quality this seat does.
