In-Ground trampolines are now practical for all backyards because Avyna's uniue design reduces soil excavation to only 3 cubic yards. Avyna Pro-Line In-Ground Trampolines introduce a great new phase in the backyard recreation revolution that began over 25 years ago in the outdoor sporting goods industry. As trampoline sales rapidly grew, parent's fear of their children falling off high above ground trampolines led to wide use of safety enclosures. Since the new Pro-Line In-Ground Trampoline is just a step above the lawn, instead of 3-feet above ground, a safety enclosure is no longer required. In addition, the Pro-Line In-Ground Trampoline design requires minimal soil removal, making it easy for home owners to install with or without the use of professionals.
Before Pro-Line’s unique in-ground design, homeowners must dig massive holes in their backyards to get the many benefits of an “in-ground” trampoline. These trampoline installations cost a lot, required major routine maintenance, and the trampolines often did not jump well.
A typical 14-foot diameter in-ground trampoline with the recommended retaining wall requires the removal of approximately 15 cubic yards of soil, whereas a similar Pro-Line In-Ground Trampoline requires only 3 cubic yards of soil removal! The Pro-Line In-Ground Trampoline sets 10 inches off the ground and with sloping sides creating a cone shaped hole, no retaining walls are required.
