I bought this several months ago and my son transitioned well on this. The mattress we used until he was 19mon was a complete piece of junk. We got it free from babies r us with the purchase of a crib. Finally got around to upgrading and he is doing really well on the quilted side. I'm happy I purchased through naturepedic so I had the piece of mind if I needed to return it. I bought the waterproof flat sheet and it has been working great! Highly recommended
