High-precision OEM/ODM trampoline models engineered for global retail networks, e-commerce brands, and commercial importers.
As global regulatory frameworks tighten under ASTM F381-16 and EN71-14, Tier-1 OEM manufacturers must bridge the gap between high-yield mass production and flawless mechanical safety.
Modern indoor kids trampolines demand a fundamental shift from rigid metal-spring mechanisms to high-tensile synthetic elastic cord systems. Traditional spring-based designs represent over 64% of injury litigation in juvenile play products due to pinch-point trauma and limb entrapment. Zhejiang Lingsha Technology (Funjump) has re-engineered indoor bounce dynamics with zero-gap elastic webbing and curved pole topographies that guarantee zero frame contact during maximum rebound cycles.
Zhejiang Lingsha Technology Co., Ltd., operating globally under the flagship brand Funjump, stands at the forefront of engineering safe, stable, and customized trampoline systems. Spanning a state-of-the-art manufacturing campus of 68,000 square meters, our facility integrates raw tube processing, automated metalworking, robotic welding, high-density textile sewing, and packaging lines under one centralized quality management standard.
Equipped with over one hundred highly skilled technical engineers and operators, our daily capacity exceeds 1,500 complete trampoline sets. We hold comprehensive international factory audits and compliance accreditations including ISO9001, BSCI, GS (TÜV Rheinland), EN71-14, ASTM F381/F2225, and AS4989. Our specialized in-house trampoline testing laboratory conducts real-time destructive load testing, UV degradation simulation, and component cycle fatigue tests to systematically eliminate defects before shipment.
Resolving historical industry pain points: How Funjump balances quick-fold portability with rigorous structural rigidity.
Traditional indoor trampolines often force a trade-off: either complex multi-bolt assembly that frustrates end-consumers or loose structural joints that wobble during play. Funjump’s engineering team patented a snap-lock button mechanism and quick-fold hinge system. Our 40”-51” fitness rebounders and 55” toddler trampolines assemble in under 10 minutes without secondary hand tools, while achieving structural deflection limits under 1.5% at peak impact.
We serve leading global brands, international trade houses, and top-ranked Amazon e-commerce sellers across North America and Europe. By providing compact ISTA-6A drop-test compliant retail packaging, custom private-label branding, and rapid order fulfillment, Funjump empowers retail partners to maintain Category #1 positioning with lower return rates and superior star ratings.
Comparing industrial-grade specifications across Funjump indoor kids trampolines versus standard market alternatives.
| Engineering Parameter | Funjump Standard OEM Spec | Generic Market Alternative | B2B Performance Advantage |

Designed specifically for toddler safety (Ages 2-6), our springless bungee cord configuration replaces rigid steel with high-grade synthetic latex strands. This delivers a smoother, lower-impact deceleration curve that protects developing child joints while eliminating pinches.
By curving the vertical safety enclosure poles away from the enclosure net, Funjump mitigates high-velocity body impacts against metal supports, drastically reducing head and upper-body impact forces during chaotic play.
Engineered for urban space constraints, our foldable 40” to 51” models feature dual-hinge lock pins that collapse the unit into a quarter-circle volume, enabling flat packaging and hassle-free domestic storage.
Every production batch undergoes destructive load tests, salt spray exposure, and 100,000-cycle bounce fatigue evaluations.
