Q: I love this air mattress! Very easy to set up and put away and very comfy to sleep on. I have slept on other air mattresses before and this is by far the best one I have ever slept on. The soft top makes it so you don't feel like you're sticking to it, but I put a blanket over it anyway for extra comfort. I have been recommending this one to all of my friends, I'm very happy with it!
