Most indoor gyms get outgrown by kindergarten. This birch frame is rated for ages 3 to 14 and takes 330 lb across the structure, enough for three children on it at once. The 42.5-in slide bed reverses into a rock climbing ramp, so one panel covers going down and coming back up, with guard rails along both edges. Textured ropes give grip that smooth cord cannot, and a 10.5-in rim brings ball tossing into the mix. Floor-fixing hardware anchors the 67.5-in frame so hard play does not shift it. ASTM and CPSIA compliant. Assembly is required.
