Has held up well despite indoor, and much outdoor use over one season, with and without water. Friends have liked it so much it's been requested at a couple of birthday parties. So far it has been used with up to 4 10-year olds, plus a toddler or two at a time. Hubby and 2 toddlers joined me to lay on it to look at clouds passing by one sunny afternoon.. about 300lbs total was no problem for this bounce house!
