Modern residential trampolines have evolved from basic back-yard toys into highly engineered kinetic activity platforms. Modern international buyers demand structural anti-tipping geometries, high-tensile hot-dip galvanization, and strict compliance with ASTM F381-16 and EN71-14 standards to mitigate joint stress and frame fatigue.
With cross-border e-commerce brands dominating platforms like Amazon and specialized retail chains, packaging efficiency, drop-test certification (IST A 6/3A), and toolless assembly have become critical competitive advantages to reduce return rates and lower ocean shipping costs per unit.
Advancements in polypropylene (PP) mat weaving densities, coupled with tapered conical spring designs, provide optimal dynamic recoil. This balances child play safety with adult impact-cushioning performance, preventing lower-limb joint stress while maintaining long-term elastic retention.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to producing safe, highly stable, and engineered trampolines. We specialize in customizing a comprehensive array of high-quality trampolines for global brands, distributors, and e-commerce leaders. Our product matrix spans indoor and outdoor systems, toddler and adult recreational rebounders, as well as specialized fitness platforms.
Driven by strict safety protocols, our operational facilities have earned compliance certifications across major global jurisdictions, including ISO9001, BSCI, TÜV/GS, EN71-14, ASTM F381/F2225, and AS4989. Our state-of-the-art manufacturing campus features a dedicated internal trampoline safety testing laboratory and specialized quality control engineers who inspect raw materials and finished goods to eliminate defects before dispatch.
With an expansive facility spanning over 68,000 square meters, fully automated robotic production lines, and comfortable staff quarters, our factory delivers a consistent daily output exceeding 1,500 complete trampoline sets, supporting seamless global procurement and resilient supply chains.
At Zhejiang Lingsha Technology Co., Ltd. (Funjump), we actively integrate user feedback and partner insights into our continuous engineering loop. A real trampoline standard of quality is measured not only by factory testing but by end-user satisfaction in real-world environments.
Historically, end consumers and retailers identified complex assembly and seasonal storage disassembly as major industry friction points. Balancing structural frame stability with easy, toolless assembly presented a significant mechanical challenge, as standard movable connectors often compromised structural rigidity.
Through aggressive R&D investments, our engineering team resolved this challenge. We developed proprietary fast-locking, high-stability joint connectors and quick-assembly folding fitness trampolines. These designs allow users to fold or erect the trampoline in minutes without compromising safety or structural integrity—earning widespread acclaim across global retail and e-commerce channels.
We take pride in fostering robust long-term OEM/ODM partnerships with foreign trade companies, international brand owners, and global retail chains. Our client network extends across North America, Europe, Australia, and East Asia. Crucially, multiple partners leveraging Funjump engineering occupy #1 Best-Seller positions on Amazon within the outdoor play and fitness categories, proving that uncompromising product reliability directly drives market leadership.
The core ethos of "Funjump" is to provide every consumer—from toddlers to adults—with a safe, joyful, and physically beneficial experience. Jumping is not limited to children; it is a powerful low-impact cardio exercise. Funjump brings safety and happiness within reach for households worldwide.
Equipped with high-precision CNC laser pipe cutters, robotic arc welding stations, and hydraulic tube bending machinery to ensure frame tolerances within ±0.5mm.
Utilizing heavy-duty computerized multi-needle sewing machines, automated fabric cutters, and V-69 UV-bonded nylon threading for 8-row mat edge reinforcing.
Automated hardware boxing, drop-test verified master cartons, and expansive finished product storage capable of staging 50+ containers simultaneously.
To secure a sustainable competitive edge, Funjump engineers trampolines around three core pillars: Metallurgical Rust Resistance, Dynamic Polymeric Fatigue Control, and Impact Energy Dissipation Architecture.

Traditional trampolines depend heavily on single-screw or friction-fit T-connectors, which tend to deform under prolonged lateral shear stress. Funjump's proprietary Reinforced T-Section Lock System integrates seamlessly into our round and rectangular product lines. By eliminating structural weld points at critical flex nodes, frame lifespan is extended by 300%, while eliminating structural wobble during high-amplitude jumping.
Full compliance with consumer product safety improvement regulations. Incorporates mandatory structural warning labels, padded pole enclosures, and stringent frame impact-deflection parameters designed specifically for US and Canadian retail markets.
Engineered to satisfy rigorous EU safety directives. Certified for non-toxicity, REACH-compliant PVC/PE chemical safety, and mechanical gap hazard prevention, ensuring no head, neck, or finger entrapment zones exist across the assembly.
Built to endure aggressive Southern Hemisphere UV indices. Our trampoline netting and PVC safety pads undergo accelerated xenon-arc weathering testing to prevent material embrittlement under intense tropical and desert conditions.
We support flexible delivery protocols, including Ex Works (EXW), FOB Ningbo (our primary deep-water port), and CIF to any designated port globally.
