We got the naturepedic mattress because I was worried about the materials used in other brands, so we decided to go with an organic one. When we got the mattress it was beautifully packed and we loved the feeling of high quality materials, but we did have a problem with the smell, it smelled a little weird. So we had to exchange it. Naturepedic changed it for us without any problems and the new one does not have that prominent smell. I believe it does smell like that because of the organic materials, maybe the wool...  I do like to sleep myself on this mattress when it's not occupied as my spine hurts because the another soft foam mattress we have (not naturepedic).  Overall we are pleased with this mattress and with the customer service, and we'll order another one soon for the other child.
