The jumping floor is the point here: 90 in by 91.5 in of reinforced 500D PVC gives kids room to bounce without colliding, and a 39.5 in slide dropping 29 in plus a basketball hoop fill out the other two zones. A wide 29 in by 27 in crawl-thru door means a child can get in and out without help. Children 3 to 12 can play within a 200 lb limit on the inflatable part and 100 lb each. Mesh protective walls guard against falls, rugged waterproof 420D oxford cloth with double-stitched seams handles seasons of use, and 8 stakes anchor it. The 480W blower must stay running throughout play.
