FlatLevel trampoline set 12 This Avyna FlatLevel is completely level with ground level, because the frame as a whole goes 22 cm deep into the ground, which also ensures a safe entry and exit. The trampoline edge of this larger round FlatLevel, in the colors green or gray, covers the double galvanized springs and can be attached in a simple way so that the edge remains in place during jumping. Due to the 70% more air permeability with the AirStream trampoline jumping mat, you achieve the best jumping result. As with all Avyna Pro-Line trampolines, the frame has a lifetime warranty and the springs have a 10-year warranty. NB, this trampoline is delivered without a safety net!
