Explore our flagship certified round trampoline models and indoor fitness rebounders engineered for global OEM/ODM distribution, retail chains, and e-commerce platforms.
Understanding structural physics, supply chain integration, regulatory compliance, and OEM/ODM capacity when sourcing from tier-1 Chinese manufacturers.
In global commercial and residential sports equipment distribution, round trampolines account for over 78% of total volume sales worldwide. This dominance is driven by fundamental structural mechanical advantages. Unlike rectangular or oval trampolines, a circular geometry distributes kinetic stress evenly across all perimeter steel frame joints and spring anchoring points. When a jumper impacts the center of a circular polypropylene (PP) mat, every perimeter spring stretches at a uniform tension vector. This natural mechanical centering pulls the jumper safely back toward the middle of the mat, significantly mitigating edge-collision risks.
For global procurement buyers, sourcing round trampolines from qualified China factories offers unparalleled economies of scale. High-speed automated pipe bending, continuous robotic welding, and standardized concentric frame sections reduce raw steel yield loss by up to 14% compared to rectangular variants. This structural efficiency translates directly to higher margin potential for international distributors, e-commerce brand owners, and brick-and-mortar sports retailers.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) stands at the forefront of China's sports equipment manufacturing sector. Operating from a state-of-the-art 68,000 square meter industrial facility, Funjump integrates structural R&D, automated metalworking, precision sewing, static and dynamic load testing, and direct export packaging under one roof.
Our workforce comprises over 100 highly skilled mechanical technicians and quality assurance engineers dedicated to defect-free manufacturing. Equipped with specialized, fully automated production lines, Funjump delivers a continuous daily output exceeding 1,500 complete trampoline sets. This robust production capacity guarantees reliable lead times even during peak holiday purchasing seasons (Q3 to Q4).
To safeguard global distributor brands, our facility houses an in-house specialized Trampoline Safety Testing Laboratory. Quality inspectors test every production batch for frame fatigue, UV pad degradation, spring cycle failure, and salt-spray corrosion resistance before shipping.
How Funjump's R&D team engineered quick-assembly, toolless folding, and ultra-stable connection systems without compromising structural integrity.
Historically, standard round trampolines presented a major end-user challenge: difficult installation and complex winter storage. Traditional designs required manual spring pullers, heavy wrenching, and multiple installers to interlock the frame. Adding movable joints often compromised structural rigidity, leading to frame wobbling or tube deformation over time.
Through iterative FEA (Finite Element Analysis) modeling, Funjump’s engineering team developed our Patent-Pending Quick-Disassembly Interlocking Frame Connector. By utilizing precision-swaged hot-dip galvanized tubing and spring-loaded locking pins, our latest 6ft to 16ft outdoor trampolines and 40"-51" foldable fitness rebounders can be assembled or folded down in up to 50% less time with virtually zero tools required.

Leveraging the Zhejiang Hardware Industrial Belt for unmatched cost-efficiencies, rapid prototyping, and scalable logistics fulfillment.
Located in Zhejiang province, Funjump operates within China's premier industrial hardware cluster. This proximity grants us instant access to top-grade structural steel tubing, UV-inhibited polymer resins, and specialized spring wire. Raw material transport times are reduced from days to hours, allowing us to absorb market price volatility and pass substantial savings to our B2B clients.
We serve as the core manufacturing engine behind several of the #1 Best Selling Trampoline Brands on Amazon, Walmart, and Wayfair. We supply customized 5-layer drop-test certified mail-order packaging (ISTA-6A compliant), barcoding, inner tray layout, and clear step-by-step multlingual assembly manuals tailored for direct-to-consumer drop-shipping.
Shipping air is the biggest margin killer in heavy sports goods logistics. Our packaging designers use computerized 3D box nesting models to optimize package dimensions. By engineering multi-box splitting for larger 14ft-16ft models and ultra-compact nested layouts for 55" toddler units, we increase 40HQ container load volume by 15-22%.
