I always stored my easy set the same way. Had it over 4 years, no problems. My only concern is the kids leaving the shed door open. I got in it the other day, only to find a chipmunk shut in. Lucky for me, (sort of) it was more interested in the pine bedding and chicken feed, than the pool. The shed is brand new, so I think it got in when the door was left open for an extended time. He didn't want to leave!
