Youngsters challenge gravity as they bound across the brightly colored confines of Jump Around Utah. The literal centerpiece of Jump Around's facility is their inflated jumping pillow, a natural 40'x25' pocket of air that construction crews discovered when they broke ground in 2010. Several inflatable structures surround the pillow, including twin slides and obstacle courses. Foam-wrapped scaffolding supports a 20-foot-tall by 30-foot-long network of tunnels and slides that kids can crawl through. While their little ones burn off excess energy, parents keep watch from the sitting area, complete with free WiFi.
