Much like see-saws and swings, trampolines are general household toys used by children and adults alike for playing. Some have found health benefits from exercising using trampolines such as cardio work-outs and lower body muscular strengthening.
There are various shapes one can choose when buying a trampoline. There are circular trampolines designed to keep the person in line with the center spot for a more straight line jump. There are rectangular trampolines which allow the user to jump at a much higher peak. And there are square trampolines which can readily fit the limited space in your house or backyard.

You might think that square trampolines are just the same as the rectangular ones. Truth be told, the answer is both a yes and a no. Yes, they are relatively the same. The thrust created due to varying forces of the spring is more powerful for both square and rectangular trampolines when compared to circular or octagonal ones. They are roughly the same shape, having four corners and four sides. And no, they are not the same in terms of area and size. A square trampoline will normally take up less space than its rectangular counterparts.
Another major contrasting difference between a rectangle and a square trampoline is the level of bouncing force created. You should know that the reason why a jumper can bounce on any trampoline surface is not because of the fabric or trampoline mat. It is not even elastic. In fact, if the fabric was elastic, it will lead to problems such as stretching and hitting the bottom floor unintentionally.
The driving force that makes people bounce on trampolines are the coiled metal springs. These springs are attached to the metal framework and on to the trampoline mat. In rectangular trampolines, the effect of the distance between these springs creates a more powerful thrust when the mat is hit. The result is a much higher bounce. This also occurs in square trampolines but the magnitude is slightly lower. The equal distances between the springs make the mat more rigid and more stable. This is why gymnasts choose rectangular trampolines over any other trampoline shapes. Gymnasts need a greater boost of height to perform their airborne maneuvers and tricks.
These characteristics of rigidity and stability of a square trampoline is what makes them the popular choice among parents and adults for their kids. Most parents do not want their kids going higher than necessary. This will also prevent the kids from hurting themselves or falling awkward due to unstable jumps.
It is common to find a foldable or detachable square trampoline. This design enables owners to easily store and carry the trampolines anywhere, at anytime.
Like any other trampolines, a square trampoline is built to last. However, due to continued usage and normal wear or tear, replacements may become inevitable. You may secure your warranty benefits to replace parts such as mats. In case that the square trampoline has already exceeded its warranty coverage, you may buy the replacement parts directly from the manufacturers or from retailers. Ensure that the quality of replacement parts is tested to prevent mishaps and accidents from trampolines.
