i only used this bed about a dozen times. it was never really all that comfortable and the last time i inflated it, a huge lump developed right in the middle making it unusable. there is no way to get rid of the lump and it is rock hard solid. it raised up about 3 inches high and is about 15 inches in diameter. its too late to send it back now so its going in the dumpster. i have since read other reviews of intex doing the same thing. i will NEVER get another intex again...i am going back to aerobeds!

Negative
