The TP Toys 12ft Challenger Trampoline features the super safe, patented, Surroundsafe enclosure. With its unique design, you can be assured that the user is within a safe enclosure thanks to its special features. Wraparound spring padding protects those on the outside from any side impact with the trampoline by cushioning the blow. On the inside, the user is completely separated from the springs which prevents any trapping of limbs between the springs when bouncing as well as any potential damage to the springs or jump mat. As well as the enclosure poles, the top rail helps to maintain structure of the trampoline; they feature foam protective pads which also help keep the user safe.A strong galvanised steel frame is ideal for those wishing for vigorous trampolining as this frame is built to last, backed up by the 5 year warranty on the frame.
