These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.

Ex Output:
Positive

not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's

It was first FW album I've listened to. And I'm afraid I'll never buy their CDs again. I don't want to waste my money. Well, I've heard FW is one of the prog metal monsters. Perhaps... Dream Theatre, for instance, doesn't have any such a pale album. This album has just some elements of progressive. If I have not heard it's prog rock group I'd never supposed it's progressive. Ok, the CD now is in used CD department and I hope I'll return some money.
