Inflated structures, slides, and games fill the climate-controlled environs of the numerous BounceU locations that speckle the nation. At each site, staff members closely monitor all activities as little ones traverse obstacle courses or pull on oversized inflatable boxing gloves. The crew also invites parents to join in on the fun, letting them bounce alongside their kids or make sweeping edicts from atop a bouncy-castle throne. In addition to open sessions, the indoor-play haven sets the stage for the Preschool Playdate program, where instructors lead games and activities. Special events include family-bounce night, which lets parents join in the bouncing or relax in the party room and do grownup things, such as eat marshmallows with a knife and fork.
