We got this for our 4 and 6 year old as a Christmas gift. They have been in it everyday, all day since then! It does have a hole in one of the yellow top parts near the access door but we can’t find it. It droops on that one side and we can hear the air hissing but can’t find the actual hole. It still works fine and must be a tiny enough hole that it’s not affecting them jumping. We’ll have to put water on it to see if we can figure out where it’s located.
