Unfortunately it must have a micro hole because over the night it deflates a bit. I put 100 pounds on it overnight, and in the morning it was sagging but still had quite a bit of air left in it. It has a built-in pump that is an excellent working condition that inflates and deflates the thing. It is a double thick mattress. It seems like such a shame to throw this much plastic and a working pump in the garbage.
