Explore our flagship trampoline systems engineered for commercial parks, indoor play facilities, and global retail distribution networks. Fully customizable according to ASTM, EN71, and GS standards.
The commercial and residential indoor trampoline industry is undergoing a structural paradigm shift driven by urban spatial constraints, heightened consumer safety awareness, and the convergence of active entertainment with low-impact physical therapy. Global market telemetry indicates that the indoor active play equipment sector is expanding at a CAGR of 6.8% through 2030, with contract manufacturing shifting toward advanced OEM/ODM providers who possess vertically integrated metallurgical, textile, and safety certification infrastructures.
Zhejiang Lingsha Technology Co., Ltd. (operating globally under the premier brand Funjump) stands at the forefront of this industrial transformation. Operating a state-of-the-art 68,000 square meter manufacturing campus with over one hundred specialized personnel, Funjump provides turnkey original equipment manufacturing (OEM) and original design manufacturing (ODM) services. By integrating raw material extrusion, robotic precision welding, automated heavy-duty textile stitching, and in-house laboratory testing, we eliminate supply chain vulnerabilities for global B2B procurement partners.
Safety and longevity in trampoline design are governed by structural mechanics and material integrity. Funjump’s engineering team utilizes Finite Element Analysis (FEA) to stress-test every load-bearing joint and spring configuration before advancing to serial production. Below is an overview of our engineering design principles:
Constructed from hot-dipped double-galvanized steel tubing (internal and external corrosion barrier). Wall thickness ranges from 1.5mm to 3.0mm, tested to withstand 500+ hours of continuous salt-spray testing without oxidation.
Utilizing high-tensile 260g/m² Permatron® UV-resistant woven polypropylene mats. Reinforced with 8-row perimeter stitching using v-ring carbon steel connectors, preventing edge tear-outs under dynamic force impacts up to 500kg.
Custom spring tuning incorporating zinc-plated wire coils with tapered waist designs for progressive deceleration. Alternative springless systems use heavy-duty medical-grade latex/TPU bungee cords for whisper-quiet indoor residential operation.

Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to producing safe, stable, and durable trampolines for global distribution. We customize a wide variety of premium trampolines tailored for commercial parks, home fitness, e-commerce retailers, and educational facilities. Our enterprise has passed international audits including ISO9001, BSCI, GS, EN71-14, ASTM, and AS4989.
Spanning an operational footprint of 68,000 square meters and powered by a highly skilled workforce of over one hundred employees, our factory is outfitted with computerized automated laser steel cutters, automated tube benders, robotic welding stations, and specialized heavy-material sewing equipment. Our production lines maintain a continuous daily output exceeding 1,500 complete trampoline sets, guaranteeing rapid order fulfillment during global peak procurement seasons.
At Zhejiang Lingsha Technology Co., Ltd., we actively integrate customer feedback into our technical iterations. Historically, global importers and end-consumers faced two significant challenges with conventional trampolines: structural instability and complex, labor-intensive installation. Achieving quick assembly without sacrificing mechanical rigidity requires sophisticated structural engineering.
Through the tireless efforts of our internal R&D engineering team, Funjump successfully introduced patented quick-assembly frame connectors and foldable fitness rebounders. Our modern mini indoor trampolines and fitness series can be assembled and dismantled in minutes without requiring specialized tooling. This breakthrough drastically reduces logistics box volume for e-commerce sellers while elevating user satisfaction.
We provide specialized drop-ship packaging, ISTA-6-TOBA drop-test verified cartons, compact nesting designs to minimize Amazon FBA dimensional weight fees, and custom branded user instruction manuals and accessories.
Our factory maintains long-term OEM contracts with top-tier category sellers on major platforms worldwide. Proven high product stability directly reduces return rates (NCAR) to under 0.1%, protecting your brand reputation.
Our 68,000 m² campus operates under clean, digitized production management protocols across four specialized workshop divisions:
Featuring fully automated CNC pipe cutters, hydraulic stamping presses, and robotic arm arc-welding cells ensuring zero-defect seam construction across all frame joints.
Utilizing industrial computer-controlled multi-needle sewing machinery with UV-stabilized bonded nylon threads for high-tensile spring pads, safety enclosures, and PP jump mats.
Heavy-duty double-wall corrugated boxing systems integrated with automated hardware sorting and counting tech to guarantee 100% component inclusion.
To safeguard global buyers from product liability risks, Funjump operates an internal specialized trampoline testing laboratory. Every batch of raw materials and finished assembly must pass 5 rigorous quality control gates before export approval:
100,000 continuous vertical drop impacts with heavy weight blocks to simulate years of intensive trampoline park or residential usage.
Destructive tension testing of springs and V-rings to verify breaking points exceed safety standards by at least 300%.
Accelerated QUV weathering chamber testing ensuring safety nets and PVC padding maintain tensile strength in extreme climates.
Phthalates, lead, and PAH chemical screening verifying compliance with EU REACH and US CPSIA toddler safety requirements.
Select from our specialized line of mini indoor toddler rebounders, rectangular competitive designs, and fitness trampoline systems available for custom OEM production.
