I have several air mattresses that I've stored rolled up for years, the best one maybe more than 10 years. No problems. Self inflating pads, though, will crunch down to where they can take days to inflate. I store those with the valves open on our camp trailer bed.

“In a time of deceit telling the truth is a revolutionary act.”
