The Berg InGround Trampoline allows you to integrate a trampoline into your garden in a neat, simple and safe manner. Loads of fun for the children without impacting on the look of your garden. The Berg InGround features a frame net that attaches to the underside preventing children, animals (and shoes!) from falling down into the void under the trampoline. It offers sufficient clearance however, to allow the user to bounce properly (completely submerging the trampoline would not allow air to escape from the void when the mat is depressed by bouncing this cushioning effect would kill the bounce). The frame is specially constructed for easy and safe installation, and is much lower than a standard above-ground trampoline. . . you don't pay for intermediate legs that are not needed. Consequently,the depth of the void into which the trampoline is sunk, is much less than if a regular trampoline were to be sunk into the ground.
