A 112 in by 118.5 in bouncy castle that ships with its 480W blower already in the box, so it inflates within minutes of unpacking. Three children ages 3 to 10 can play inside a 300 lb total limit, with 100 lb allowed per child. Beyond the jumping floor there is an inflatable basketball with its own hand pump and 100 ocean balls for a ball-pit corner. Mesh walls run around the castle to contain jumpers and move air through on hot afternoons. Layered 420D and 840D oxford cloth with tight stitching absorbs the abuse, and six ground stakes hold the 36 lb unit down.
