I was so excited to try this airbed on our camping trip. But......it was a total disaster. Who ever designed this obviously didn't try sleeping on it. There are not enough separate cells in this mattress so it is one mass of air. Since my husband weighs more than me: he sank into the mattress and I was on a higher bump. After one night of sliding to the low side, my husband slept on the tent floor after that. I threw the mattress away when i got home,Its a great idea, to bad it wasn't designed more carefully.
