Pump It Up

Pump It Up's indoor inflatable arenas bounce socked younglings high off the ground with a plethora of kid-friendly bounce pads. Trained, amiable staffers supervise fun-filled visits in which parents can leap around with their kids through gargantuan, air-filled bounce houses, skip down air-filled slides, and slither like snakes covered in bacon grease through an air-filled obstacle course. Attendees can also focus their free play for special events, such as custom birthday parties and private team parties. These themed soirees immerse children in a schedule of interactive activities befitting a pirate or a superhero while melting off youthful energy faster than ice cubes thrown into a running DVD player.

The giant arenas are climate controlled and maintained according to rigorous guidelines enforced by the well-trained staff and local police. Supplementing its thorough rule enforcement with expert installation and anchoring of inflatables, Pump It Up holds itself to strict safety standards.
