Pro-Line trampoline set 12 with HD safety pad. This round Avyna PRO-LINE trampoline has a diameter of 365 cm and has a heavy quality PVC edge with an extra thick filling. All our edges provide complete coverage of the springs and trampoline frame for extra safety. Our trampolines belong to the high segment and are excellently finished with a lot of attention to the small details, including the heavy stitching and the firm attachment. Unlike other trampoline brands, we give a five-year lifetime warranty on the frame and edge. The difference between a trampoline with an HD-Plus edge and our normal Pro-Line edge is that the HD-Plus edge is extra thick (3.5 cm) and contains Vinyl (0.8 mm). The HD-Plus edges are designed so that no water remains on them.
