Ordered two of these mattresses and both did not inflate properly. We carried these two heavy boxes up a flight of stairs, waited nearly a week for them to puff up, only to learn they would never fully inflate and were defective. It's hard to see from the photo, but if we put a small child in the bed on the left, they would roll out as the entire mattress is dipping on the right side. The one on the right has not deflated near the headboard, so someone's head or feet will always be much lower than the rest of their body. I'm waiting to see what Wayfair does. Will we have to repack these or pay $30 for our garbage company to haul them away? Either way a hassle and expense to us.
