content: This overpriced mattress is not as convenient as the commercials would have it. First of all you need a 2Xgh adapter and who has those in their homes to begin with? Secondly, you have to oil the motor with lubricant because it is a fan based turbine engine and it overheats really easy so if you keep on deflating it and then inflating it you are going to have major problems. The best thing to do is just buy a plain mattress and put it on the floor, it is probably a lot more comfortable than this plus you can eat corn on the cob.
