Well, I'm on the second bed right now. I use this bed everyday, not just as a guest bed. When we first bought it after about two weeks the seam on the lower right end of the bed began to show wear. Soon after my boyfriend and I were rolling into each other in the bed because it had deflated so much. It had a leak. I tried to use the patch that came with the bed and it did not work. I wound up using a tire repair kit. The seam must have been bad because it wound up blowing about 7 holes in all. I repaired as many as I could but it wasn't getting any better so I returned the bed. Amazon was very good about the return, I was able to keep the other bed while waiting for my new one and that's one of the reasons why I labeled the bed "OK". The ohane I have now we've had for about a month and a half and it's been holding up. The lower right corner looks a little worn but hasn't sprung a leak. Oh yeah, and about the memory foam, it's not the greatest. He doesn't like it, I think it's subpar defiantely. But it is only 1 inch thick. We've been looking for a topper to put on the bed. Well that's what I think!
