Our medium round trampoline is the best of both worlds – not too big and not too small. A soft bounce designed for medium-sized yards and children of all ages.
No springs = More jumping space
The jumping surface of our 10ft round trampoline is equivalent to that of a 12ft round trampoline with springs. The medium round trampoline allows you to maximize your jumping surface while saving valuable backyard space.
