This mattress is super comfortable! I ordered a full size one for my three year old. At night when I tuck her in I easily fall asleep next to her (not on purpose). My husband likes it too. We joke that she has a better bed than we do. The only thing I wish was better, the edges are not reinforced. Meaning that I'm 5'7" at 145lbs and the sides squish about half way down when you sit on them. When I opened the packaging there was no smell and the bed expanded quickly. We didn't have to wait long at all to make the bed. Overall, I highly recommend this mattress!
