Avyna trampoline set 14 with safety net and free ladder The Avyna Pro-Line trampoline set 14 has a diameter of 430 cm, making it the largest round surface-mounted trampoline we have. All our trampolines meet all safety requirements and have been tested as the best. If you choose Avyna, you go for the best quality and safety. The trampoline has double galvanized springs and is equipped with a sturdy and extra thick safety pad. We give a lifetime warranty on the trampoline frame. With a trampoline combination package from Avyna you are completely complete and safe from the first jump. Due to the renewed safety net, which ends halfway up the trampoline edge from a safety point of view, the design is even tighter than it already was and can be found in every garden. Because safety is a priority at Avyna, we provide a free ladder to make getting on and off the trampoline easier. Prefer to dig in? Look here for a round InGround, or would you prefer a round FlatLevel?
