The blowup mattress was exactly the size I ordered. Unfortunately, I did not realize the one it was replacing was actually a queen (blowup) mattress (inside a full sized pillow top sofa sleeper mattress). The size is not displayed. That is completely on me. Given the application it may last the lifetime of the sleeper. The only reason the other one was damaged is because a guest folded the mattress back into the sleeper without deflating it - an almost impossible feat! Lol. Anyhow - super good quality. I don't necessarily like paying that much for an air mattress but they are far superior to any inflatable mattress I have come across before. Note: Don't just tell your guests it inflates and deflates at the press of a button, show them! :). Oh yeah - inflation/deflation times is maybe 3 minutes, max. Hit the button and walk away.
