The global sports rebound apparatus market has experienced a fundamental technological pivot over the past decade. While circular trampolines historically dominated the mass residential market due to lower structural manufacturing costs, modern engineering insights and commercial procurement trends overwhelmingly favor rectangular trampoline systems. As a primary manufacturer operating out of Zhejiang, China—Zhejiang Lingsha Technology Co., Ltd. (Funjump) leads this technical transition through advanced metallurgic processing and kinetic vector research.
Unlike circular frames where every spring stretches toward the center point regardless of impact location, rectangular trampolines utilize dual-axis independent spring reaction. This prevents the "center-pull effect," allowing jumpers to achieve predictable, vertical lift anywhere on the jumping mat—a non-negotiable requirement for competitive gymnasts and safety-conscious commercial facilities.
Urban backyards and indoor amusement centers require tight spatial optimization. Rectangular geometries align cleanly with yard boundaries, fencing, and building architecture. A 8x11FT or 7x10FT rectangular footprint yields significantly higher usable jumping area relative to total yard coverage compared to round equivalents.
Rectangular structures experience uneven torsional stress along the long side rails. At Funjump, we utilize heavy-gauge, hot-dip galvanized steel tubing (up to 3.0mm wall thickness) equipped with patented corner gussets and T-junction connectors to fully neutralize corner shear forces and frame warping under high kinetic loads.
For global brand owners, importers, and Amazon top sellers, product structural integrity dictates warranty claim rates and brand equity. Funjump’s specialized manufacturing methodology delivers an operational product lifespan exceeding 8+ years under constant outdoor exposure, supported by UV-50+ polypropylene weave fabric and anti-corrosive zinc-rich coatings.

Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to producing safe and stable trampolines and can customize a variety of high-quality trampolines for you, including indoor and outdoor, adult and children, fitness and leisure, and so on. We have passed many certifications including ISO9001, BSCI, GS, EN71-14, ASTM, AS4989, and our factory is equipped with a specialized trampoline safety testing lab and inspectors to weed out defective products for you in advance.
Our factory covers an area of 68,000 square meters, with more than one hundred excellent employees, equipped with professional automated production equipment and comfortable staff dormitories, production line daily output of more than 1,500 sets of trampolines, you are always welcome to visit us.
We are also very happy to adopt every customer's opinion, because Zhejiang Lingsha Technology Co., Ltd. (Funjump) is not only our factory, but also every customer's, only the good trampoline recognized by customers is the real good trampoline. For example, before there were a lot of customers giving us feedback that trampoline installation and storage was difficult. This is a common problem across the industry because balancing quick installation with trampoline stability requires engineering movable parts and fast-dismantle connectors, which can affect overall structural rigidity.
Now, through the dedicated efforts of our engineering team, we designed a foldable fitness trampoline and a mini trampoline that can be quickly disassembled and assembled with almost no tools, earning widespread recognition from our client base worldwide.
We are proud to establish long-term partnerships with leading international trade corporations, brand owners, and e-commerce leaders across global markets. Many partners—including top-ranking vendors on major e-commerce platforms like Amazon—rely on Funjump due to our consistently high manufacturing quality and proactive aftermarket support. The brand philosophy of "Funjump" is to let every customer experience safe, joyful jumping. Joy is truly at your fingertips!
Clients submit baseline dimensional requirements (e.g., 6x9FT, 7x10FT, 8x11FT, or custom sizing). Our engineering division designs 3D CAD frames, performing finite element analysis (FEA) to verify frame bending moments and load distribution.
Before mass manufacturing, physical prototypes are built and subjected to 100,000 continuous cycle bounce tests, salt spray exposure tests, and dynamic enclosure impact tests inside our internal testing laboratory.
Utilizing robotic automated welding units, automated CNC tube benders, and computerized multi-needle sewing machinery, we maintain strict dimensional tolerances across daily volumes exceeding 1,500 units.
We provide full white-label OEM branding: customized color boxes, high-density drop-test mail-order packaging, multi-language instruction manuals, branded spring pads, and logo-printed jumping mats.
Every production batch includes full compliance documentation supporting ASTM F381-16, ASTM F2225-15, EN 71-14:2018, and AS 4989 standards, allowing frictionless customs entry into North American, EU, and Australasian ports.
Rectangular trampoline packaging is mathematically optimized for CBM container density. Our packing layouts maximize 40ft HQ container utilization, lowering ocean freight cost per unit for our importers.
