Family backyards with active kids and visiting friends need a bigger bounce zone and this 15 ft heavy duty trampoline delivers a 180 in deck on an anti rust steel frame. The reinforced chassis carries up to 470 lbs so groups of jumpers can play together while the full enclosure net with zipper door keeps everyone inside the bounce area. Astm testing covers spring strength frame welds and net seams so parents start with a safety-rated platform.
