Named after the Australian 2 meter tall alpha male kangaroo, The Boomer® should be treated with the same respect for it is a seriously powerful performer! The name reflects both the trampoline’s Australian heritage and its fearsome ability. The huge competition size 2 string bed is coupled with a super heavyweight slot together galvanised 60mm diameter steel frame. Side rails are double thickness. The 118 x 235mm ‘bezinal’ treated steel springs provide astonishing performance. Please note that this trampoline cannot be folded like a sports hall trampoline. Its solid state makes it incredibly strong.
