I have a Queen Sized Aerobed with built in pump. When fully inflated, it stands about 2.5 feet tall. It is very comfy. I inflated it today and there is a very small leak (I have marked it with a piece of tape) I do not have the supplies to patch it, but if you have a vinyl patch and glue, it would be an easy fix. Normally, these beds cost over $100 new.
