Indoor Trampoline Park

Indoor Trampoline Park 

•Sky Zone. Sky Zone opens its seventh arena this summer in Orlando, with 12 more in development, owner Jeff Platt says. "Who doesn't love being free from the Earth's gravity?" he asks. He even got his 81-year-old grandmother on a trampoline, "but she wasn't doing back flips."

•Sky High Sports. The company has eight locations now, half of which are in California. Three more open this summer; two in the Chicago area. Co-owner Jerry Raymond quit his job as a computer consultant to open the company. "I was looking to do something where my kids wouldn't be embarrassed to come to work with Dad," he says.

•Jumpstreet. Seven are operating, mostly in Colorado, and six more are in development. Owner Tim Crawford says he came out of retirement to start the company after dreaming that his backyard was filled with trampolines.

•Rebounderz. There's one in Longwood, Fla., and one opens this month in Sterling, Va. The firm has video cameras and referees tracking safety, CEO Mark Gurley says.

•Xtreme Trampolines. Eric Beck, a former Burger King franchisee, owns one unit in Chicago. "If it's cold or rainy or snowing, we're packed," he says. "If it's sunny outside, we're empty."
