Inflatable castles (also called bounce houses, bouncing houses, jumpy house, bouncing castles, bouncy houses, jumping castles, jumpers, jolly jumps, bouncy castles, moon bounces, closed inflatable trampolines [CITs], or moonwalks) are temporary inflatable structures and buildings and similar items. They are rented for backyard and block party functions, school and church festivals and village fetes and used for recreational purposes. The growth in the use of such devices has led to a rental industry that includes inflatable slides, inflatable water slides, obstacle courses, and giant games, carnival games, and more.
Inflatable castles have been suggested as having some therapeutic value for children with certain sensory impairments, similar to ball pits.[1]
