Query: A Piece of S**T

This was a big waste of money. The first day of use, my two guest had to pump it back up about five times throughout the night.I thought maybe it was because two people were on it. A couple of monthe later I had another guest sleep on it. He had to do the same thing. IHe ended up sleeping on the couch. He thought it was a mre comfortable sleep anyway.Again, DO NOT WASTE YOUR MONEY!!!
