Sprightly bouncers must wear socks in order to play. Adults and nonwalking children enter open bounce for free with a paid child admission.

BounceU transports kids to an inflatable, climate-controlled playground, where they can bounce from side to side in a safe, secure environment. Children can practice for future careers as catapult payloads during any of the open-bounce sessions—including preschool playdates, family bounce nights, and all-ages open bounces—scheduled at various times throughout the week. Adults are welcome to act like 8-year-olds and join the vivacious youngsters in the playground, where they can duel with the foam-shooting equipment, mount the climbing structures, or imagine they're synchronized leapers in Michael Flatley's Riverbounce. The attentive BounceU staff will monitor the rebounding playground at all times, ensuring that the facilities are safe and clean. Not every location has every type of open-bounce session, so take a look at the Blackwood, Cherry Hill, Horsham, Langhorne, Oaks, and West Windsor calendars to find a time and session that works best for you. Call the Exton location for a schedule.

BounceU's summer camps combine the inflatable fun of the indoor playgrounds with exciting camp activities such as games and songs, with a special focus on artistic expression. A ratio of one counselor to every 10 campers ensures playtime safety and a supportive environment in which to channel inner muses into colorful paintings or pointillist reinterpretations of Grover Cleveland's presidential portrait. Different locations have different hours and cater to different ages, and some have camp themes that change each week. Check out the following locations to see each camp's age range, theme schedule, and operating hours: Blackwood, Cherry Hill, Exton, Oaks, and West Windsor.
