I have had this mattress for a few weeks now. Not once have I had to adjust it. I just put it on my bed frame with slats and it has been one of the most comfortable mattresses I have slept on. I had a memory foam mattress and before that an inner spring one. I have always liked sleeping on mu Sealy air mattress when camping but this one is even better because it is not as big and the cover makes a difference and though not cooling it doesn't get too warm either. Good value, great price; love the mattress. Thank you.
