Our large square trampoline has a soft bounce and plenty of jumping space. Designed for large yards and children (and adults!) of all ages.
No springs = More jumping space
The jumping surface of our 11ft square trampoline is equivalent to that of a 14ft square trampoline with springs. The large square trampoline allows you to maximize your jumping surface while saving valuable backyard space.
