Very high quality trampoline bed sized for 6' X 12' rectangle trampolines. 6' x 12' is the measurement of the bed itself. Our 6' x 12' beds have 96 spring rings, 32 on each long side and 16 on each short side. All of our trampoline beds have a sun-guard. This strip of blue webbing sewn around the edge of the bed helps keep the threads from rotting and deteriorating in the sun. The triangle spring hookups are welded closed to prevent bending under spring tension. Triangles are zinc plated to prevent corosion. Mastercraft Trampoline has been manufacturing the highest quality, longest lasting, and nicest looking replacement trampoline beds and safety pads in Denver, Colorado since 1966.
