Purchased 2 twin size for guest rm. Did as instructed: inflated, waited, deflated, times 3 in two days. We haven't used them yet for guests, but overnight without being used, seem to lose only a very slight amount of air - not enough to be unhappy, but not perfect enough for a 5 star rating. The flocking on the top is sufficient. Twin bedspread reaches to the floor nicely. Regular twin sheets, cheap from *******, fit nicely and stay on. With the mattress pad, it feels warm and comfortable. It is quick and easy to inflate and deflate. A little, deep cup built into the end where the cord is, makes a nice cord-tuck space for storage when it is all folded. Bag for storage looks like it will not last long, flimsy and thin. Overall this is sufficient for our needs. Wish I had held out for the never flat one that adjusts throughout the night&********
