This safety mat protects the jumper from falling on the steel frame or being injured by the springs. Our high-quality mat covers the frame and springs of your trampoline. It contains high-density, closed-cell shock-absorbing foam. This foam does not absorb water, is not affected by mildew and does not lose its shape. The top and bottom of the mat are made of UV-resistant PE. Designed for use with 13ft/3.96m trampolines, this mat overlaps the edge to ensure minimal gaps.
