Do NOT buy! It arrived yesterday and after carefully opening the package I inflated it. It inflated perfectly. However, I left it in the guest bedroom inflated and without any weight on it just to ‘test’ it. When I came back an hour later,  the mattress had deflated a bit so I inflated it again. This time I left it overnight. I checked this morning and the mattress had significantly deflated. Now I’m left scrambling to find another as I have guests coming.
