A new indoor trampoline park, called House of Air, opened this week in the Presidio area of San Francisco. And sure, the facility -- which is 2,000 square feet built inside an old airplane hanger at Crissy Airfield -- will host birthday parties for kids, but it'll also be a training center for pro action sports athletes.

Bay Area native and Winter X Games superpipe skier Matt Duhamel will be training at the facility and former Olympic mogul skier Jonny Mosely, who spends most of his year in the Bay Area, will be coaching and offering training sessions for rookies.

The facility is owned by Paul McGeehan and Dave Schaeffer, who met on a snowboarding trip in Tahoe in 2003. "The trampoline park concept is a revolutionary new action sports destination that is quickly gaining national popularity, and we are thrilled to be the first to bring it to San Francisco," said Schaeffer. "There is something for everyone at House of Air, from professional-level athletes to weekend warriors."

Mosely, who appears in the latest Warren Miller film, "Wintervention," says he's planning to train at the facility, even though he's no longer competing as a pro athlete. "These aren't your typical backyard trampolines that you get at Costco," Mosely told ESPN. "Part of the facility has real, professional-level trampolines, like the kind Olympic gymnasts use, and these trampolines let you get a lot smoother rebound and more height."

The House of Air's main room features 42 connected trampolines that fill a space larger than a regulation-size basketball court. And there are trampolines set at angles to the floor, so, as Mosely says, "you can literally bounce off the walls." There's also an area called 2X Bowl that's a freestyle trampoline concept -- which includes two three-sided bowls separated by a spine -- that's modeled after skateboard park designs.

There's also a foam pad where you can practice landing your jumps. "When you're trying off-axis tricks, landing on a trampoline can eject you in an odd direction," Mosely says, "but landing on a pad dampens the rebound. And it's more realistic to skateboarding, skiing and snowboarding."

Novices can sign up for skills sessions to work on tricks applicable to snowboarding, skiing, wakeboarding, skateboarding and kite boarding. You can rent a board -- snowboard or skis -- that straps to your feet and is meant to use on trampolines. Action sports movies will play on a 23-foot-tall projection screen and a house DJ will spin for special events.
