The square format offers distinct advantages over circular models. A round trampoline forces all perimeter springs to pull inward toward the center.
In contrast, a 15x15 square trampoline uses independent spring banks along its four straight rails. When a jumper lands off-center, only the local spring groups compress. This yields a higher, more energetic rebound near the edges.
You need a clear, flat lawn area measuring at least 21 feet by 21 feet to account for the 3-foot clear safety clearance required on all sides.
The 15x15 square trampoline delivers a massive 225 square feet of usable jumping space.
The 15x15 Avyna Pro-Line MAX features 144 heavy-duty, double-galvanized 8.5-inch Power Springs™ that maintain uniform canvas tension across the entire square.
Yes, a square trampoline is structurally better for multiple jumpers than a round model because its straight spring banks do not pull jumpers toward a central focal point.
The 15x15 square delivers 225 sq ft of jumping canvas, while the 12x18 rectangle provides 216 sq ft. The 15x15 offers a wider, more open layout for general play, while the 12x18 offers a longer runway for gymnastic tumbling.
The 15x15 Avyna MAX comes with an authentic Lifetime Frame Warranty, a 10-year warranty on springs, and a 3-year warranty on both the jumping mat and safety padding.
The 15x15 is a flush-mount in-ground trampoline; there are no above-ground versions of the square trampoline at this time.
