I bought this mattress for my 2-year-old after having owned their crib mattress. She loves her new bed and mattress! It was important for me to have a mattress free of chemicals and that will also last me a long time. This comes with a 10-year warranty. It is very comfortable, you do not feel any springs. And the best part if you lay next to your child they can't tell when you get up because it barely moves. Personally, I love that real wool/lamb smell. Reminds my childhood with my grandparents. Thank you so much Naturepedic for creating the best mattresses for babies and kids without anything harmful.
