The Top enclosure design is unsurpassed in safety and durability: Featuring flexed poles that absorb the movement of the jumper while holding the net straight and firm; a top ring that holds the net at full height without any strain from jumpers that would risk the net tearing; and clips and a rope that seal the connection between the jumping mat and the safety net, so that there are no gaps compromising safety. Along with a high-quality safety pad made of the best shock absorbent foam to prevent spring related injuries and a dual-closure entry system, this trampoline guarantees your safety. All the materials are water and UV resistant and the foam protector is fashioned from high density, closed-cell EPE foam that will not absorb water, mildew or lose shape; your trampoline will maintain its protectiveness and strength no matter what.
