The rectangular big trampoline is universally recognized as the performance standard for gymnasts and serious jumpers, and its design principles are rooted in physics. The rectangular shape allows for springs of uniform length to be placed along all four sides. When a jumper lands in the center, the force is distributed evenly to all springs, resulting in a direct, powerful, and vertical rebound. This is in contrast to round trampolines, which create a directional bounce towards the center. This predictable and high lift is essential for practicing aerial skills safely and effectively. JYTrampoline's rectangular models are over-engineered to handle this intense, focused energy. The frame is constructed with thicker-gauge steel and features double-walled legs and reinforced T-joints at the corners to prevent flexing and fatigue. The spring system is exceptionally dense, utilizing a high number of long, high-carbon steel springs to generate the necessary thrust. The bed is made from a low-stretch, high-tensile material that efficiently transfers energy. While it offers the best bounce quality, it is important to note that this power requires a greater degree of body control and is generally more suitable for older children, teenagers, and adults. For the user seeking the ultimate trampolining experience, our rectangular big trampoline delivers professional-level performance and durability in a backyard package.
