I have purchased 2 of these from Amazon over the past year and each time, my guest ended up laid out flat. The most recent one didn't last 1 full night. The air slowly seeped out as soon as I inflated it. I actually had to put more air in it during the middle of the night to keep it inflated. On the second night, all the air seeped completely out and when I attempted to inflate it again, the mattress actually popped. The resulting hole was too big to repair so I sent the mattress back and will not purchase another again.Be forewarned.
