How do I know if I need a Round Trampoline or a Rectangle Trampoline?
On round trampolines all the springs work at the same rate. This gives an even, softer, and more stable bounce, suitable for children of any age (6 & older) or ability. A round trampoline has a "center soft spot" in it and therefore, it does tend to control your bounce, by putting the jumper back into the center of the trampoline. Round trampolines at the higher end are all suitable for adults.
If your kids are active in tumbling and gymnastics and or you want the "very best bounce" from a trampoline, then by all means go with a Rectangle Trampoline. By design, a rectangle trampoline will give you the highest bounce of any trampoline. On rectangular trampolines, the springs work at different rates giving a quick response and this action results in a more powerful lift. This makes it more suitable for gymnastic use. However, because of these characteristics rectangular trampolines should only be used by one jumper at a time. A rectangle trampoline does not have a "center" spot in it and therefore, it does not control your bounce, by putting the jumper back into the center of the trampoline. This allows the jumper full control of the placement of their jumps. The long straight sides allow the jumper to do tumbling routines with ease. A rectangle trampoline is great for gymnastics and cheerleading routines.
A Trampoline Enclosure is highly recommended with any aggressive jumping style routines to help prevent the jumper from leaving the trampoline unit.
