Avyna’s Pro-Line has been Europe’s largest selling premium trampoline since it was introduced over fifteen years ago. Avyna’s “FlatLevel” Models almost make the trampoline disappear from view while still providing the family the joy of safe trampoline fun. These models are the very easiest for homeowners to install of any ground-level trampoline on the market today. They can be installed with or without the use of professionals. Avyna’s design team solved the problem of excavating the air from its ground-level trampoline excavation with an exclusive new breathing jumping mat fabric which passes 70 percent more air. All other in-ground trampoline manufacturers are still offering extremely poor solutions for this inherent in-ground problem. Avyna’s high-quality trampolines have been approved and tested by TUV which established the highest safety standards for trampolines in the world. No other trampolines sold in the United States have been so rigorously tested. Meets or exceeds ASTM Specifications – the American standard.
