Here's what the Seattle Gymnastics Academy has to say about it, "A chance for young children, ages 12 months to five years (yes, 6 and up is too old) to play in our gym. With parental supervision, young gymnasts play, jump, run, climb, swing, bounce, push, roll, hang, balance and hop on SGA's wide variety of gymnastics equipment. The trampoline and Tumbl Trak are common favorites, not to mention our huge foam pit surmounted by a child-sized climbing wall. Come join the fun. Some equipment is off limits, but all the fun stuff is there for your child's pleasure." Cost is $6 per child.
