At Zhejiang Lingsha Technology Co., Ltd. (Funjump), we are committed to engineering world-class, ultra-safe, and structurally resilient trampolines. As a premier original equipment manufacturer (OEM) and custom solution provider, our operational scope spans full-scale R&D, structural design, metal fabrication, textile weaving/sewing, precision assembly, and rigorous quality assurance. We customize a comprehensive portfolio of high-grade recreational and athletic trampolines—including indoor and outdoor, adult and children, fitness rebounders, and large-scale commercial play structures.
Our facility operates under stringent international management frameworks, holding fully verified certifications including ISO9001:2015, BSCI (Business Social Compliance Initiative), TUV-GS, EN71-14, ASTM F381 / ASTM F2225, and AS4989. Unlike standard assembly factories, Funjump maintains an internal, dedicated Trampoline Safety Testing Laboratory staffed by certified QC inspectors. This facility is equipped with automated tensile strength testers, salt spray corrosion chambers, UV degradation spectrometers, and impact drop testers to guarantee zero-defect manufacturing before shipment.
Spanning an expansive footprint of 68,000 square meters, our facility houses state-of-the-art automated tube-bending robotics, laser welding units, multi-needle stitching lines, and comfortable employee dormitories. With an active production line daily output exceeding 1,500 complete trampoline sets, we seamlessly accommodate global high-volume seasonal spikes for major retail networks, global e-commerce category leaders (such as top-ranking Amazon merchants), and international distributors.
Analysis of shifting consumer demands, safety standard evolution, and strategic procurement dynamics across North America, Europe, and Asia-Pacific.
Global consumers and regulatory bodies have elevated safety requirements from passive protection to proactive structural engineering. Demand has shifted sharply toward internal net enclosure systems (where safety nets attach inside the spring system to prevent limb entrapment), curved enclosure poles wrapped in thick EPE foam, and high-density, zip-and-clip dual enclosure doors. Suppliers must meet these strict criteria to survive in tier-1 markets.
With the rapid growth of direct-to-consumer (D2C) channels and e-commerce giants like Amazon, Wayfair, and Mercado Libre, logistics optimization is paramount. Modern buyers demand compact, drop-test-certified single-box or dual-box packaging that minimizes volumetric shipping costs while passing ISTA-6A transit testing without frame deformation or missing hardware.
Historically, assembly friction was the primary cause of negative consumer reviews. Modern B2B sourcing prioritizes patented self-locking T-joints, snap-button leg extensions, and tool-less spring pullers. Funjump’s R&D department has addressed this key pain point by engineering fast-assembly frame frameworks that reduce consumer installation time by up to 50%.
Inside Funjump’s specialized manufacturing units: Metalworking, Industrial Sewing, Packaging, and Quality Assurance Testing.
Our metalworking shop utilizes high-precision cold-roll tube benders, automated punch presses, and robotic arm seam welders. Every frame segment uses internal and external hot-dip galvanized steel tubing (up to 1.8mm–2.5mm wall thickness), providing superior protection against rust and environmental corrosion in salt-heavy or humid climates.
Our textile shop manufactures high-durability polypropylene (PP) jumping mats, PVC frame padding covers, and PE mesh safety nets. Using heavy-duty computer-guided 8-row perimeter stitching with UV-resistant bonded nylon threads, our jumping mats prevent edge tear-outs even under high dynamic load impacts.
Every complete unit is systematically packed using high-burst 5-ply or 7-ply corrugated export cartons. Structural foam partitions and hardware blister packs ensure scratch-free shipping transit.

Solving industry challenges through custom design, simple assembly, and proven compliance.
At Zhejiang Lingsha Technology Co., Ltd. (Funjump), customer feedback directly guides our R&D roadmap. Historically, complex frame assembly and difficult off-season storage were major consumer complaints across the global trampoline industry. Balancing ease-of-assembly with structural rigidity is a significant engineering challenge, as adding moving joints or quick-release mechanisms can compromise frame stability under high dynamic stress.
Through continuous iteration, our engineering team successfully developed a patented tool-less quick-assembly framework and a space-saving foldable fitness trampoline series. Featuring pre-assembled snap-locking connectors and heavy-duty hinges, these designs allow end consumers to set up or disassemble their trampolines quickly without specialized tools, while maintaining structural rigidity and meeting EN71 and ASTM safety requirements.
We take pride in building long-term strategic partnerships with leading international trading firms, retail chains, and major e-commerce sellers. A significant portion of our production supports top-ranking brand owners on major global e-commerce platforms, including Amazon. By providing consistent product quality, robust mail-order packaging, and custom SKU designs, Funjump helps our partners maintain high review ratings and scale their market presence.
The core philosophy behind the "Funjump" brand is simple: to ensure every user experiences safe, high-energy jumping fun. Trampolines are not just for children—they offer cardiovascular fitness and recreational benefits for all ages. At Funjump, we put joy and safety within easy reach!
