Did not want to derail Chadwife thread. I see a few people would not give up their Sleep Number mattress. Do you have a adjustable frame? if so, how do you keep your pillows from falling between the mattress and head board when completely flat? I can move my mattress a couple inches closer to the head board to close the gap but after 3 days I have to move it back up. If not all my pillows are on the floor. Sleep Number has come out to make sure that them mattress is screwed to the base and it is.
