Intex 20" Queen Dura-Beam Deluxe Raised Air Bed Mattress with Built-in Pump

This seems to be a sturdy, well made inflatable mattress. It doesn't feel cheap at all. The material it's made from feels thick and substantial. Plug it in, and the built-in air pump inflates quickly. I didn't see any kind of automatic shut-off, so you'll need to watch it and shut it off when the mattress gets to your desired firmness. The directions warn that it can burst if over-inflated. I filled mine, then tested it. I let some air out to get a more cushiony feel. It never felt saggy, even after letting air out. The directions are clear and short. There is a small patch included if you need one later on. The item description says that the mattress sits 20" high. I measured mine, and it's more like 21" or 22" which is fine with me. Kitchen chairs are about 18" high, so this mattress definitely sits high enough to be easy to get up and down off of. I have this mattress in my guest room, which is also the grandkids' video game room. I cover the mattress with a quilt and they use the mattress as a couch. The first night I got the mattress, I slept on it, just to see if it was comfortable. It's got a firm surface, so I covered it with a folded comforter for a little padding. I did not expect to sleep very well or very comfortably, but I absolutely did. It is a twin size, great for one person. The thick edges are raised, so you don't feel like you're going to roll off. The mattress stayed perfectly inflated all night. There was a slight 'new vinyl' smell, but it faded away after a day or two. It's so tall, you're not going to be able to put a fitted sheet on it, but that didn't particularly matter to me. If you're camping, it probably doesn't matter to you, either. If you're camping, I would definitely put something under the mattress to prevent sticks or rocks from piercing the mattress, but you'd do that with any inflatable item. It feels sturdy, but why risk it? I've had this mattress set up for a couple of weeks now, and the grandkids have used it several times. There has been no loss of air. I am lighter weight, about 125lb, so I can't speak to the mattress supporting anything heavier than that. I am happy with my purchase, would buy it again, and would recommend it to a friend. It's not the least expensive inflatable mattress you can buy, but it's worth it in my opinion. Hope you enjoy it!
