FlatLevel trampoline set 10 The Avyna FlatLevel trampoline is level with ground level, both the top frame and the bottom frame go 22cm deep into the ground and are therefore beautifully integrated into your garden. The edge of this medium-sized round trampoline covers the double galvanized springs for extra safety and is attached in a special, but simple way. This keeps the edge firmly on the trampoline while jumping. You get a lifetime warranty on the springs and a 10-year warranty on the double galvanized springs. The AirStream trampoline jumping mat, with 70% more air permeability, ensures the best jumping result. To make the trampoline even safer, we also have this trampoline including a safety net.
