Explore our high-demand engineered trampolines, built to comply with ASTM, GS, EN71-14, and ISO standards for commercial, fitness, and residential applications.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) operates as a leading high-tech manufacturer specializing in the structural design, materials engineering, and volume production of custom professional gymnastics trampolines, commercial recreation jumping systems, and fitness rebounders. Located in the manufacturing hub of Zhejiang, China, our state-of-the-art facility covers 68,000 square meters. Managed by over one hundred expert technicians and production specialists, the plant is integrated with fully automated metalworking, precision robot welding, automated polymer weaving, and specialized sewing lines capable of yielding a daily production volume exceeding 1,500 sets of finished trampolines.
Safety engineering and technical reliability form the core of Funjump's corporate ethos. We maintain a dedicated in-house trampoline safety testing laboratory equipped with dynamic impact testing rigs, tensile strength testers, salt-spray anti-corrosion chambers, and UV degradation acceleration chambers. Our factory maintains compliance with major international governance standards, including ISO9001:2015 Quality Management Systems, BSCI Social Compliance, TUV/GS safety marks, EN71-14 (European Safety of Toys), ASTM F381-16 / ASTM F2225-15 (American Safety Standards), and AS4989 (Australian Trampoline Specification).
The global market for professional gymnastics rebounders, commercial trampoline parks, and residential training gear is undergoing a structural transition driven by rising standards in biomechanical safety, structural durability, and modular setup requirements. Traditional consumer trampolines historically suffered from rigid frame fatigue, spring noise, degradation under extreme weather, and labor-intensive assembly processes that discouraged fast deployment in commercial fitness clubs or outdoor sports institutions.
Funjump addresses these industry friction points through continuous metallurgical and mechanical innovation:
Leveraging Zhejiang's world-class industrial cluster for sporting goods manufacturing to deliver superior quality, compliance, and cost efficiency.
By controlling raw material sourcing—from raw steel pipes and non-toxic EPE foam padding to UV-treated PE safety netting—Funjump drastically reduces production lead times while eliminating middleman markups. This vertical Integration enables us to offer competitive wholesale FOB/CIF pricing for global buyers.
Our quality control protocol involves rigorous 7-stage inspection criteria: raw material metallographic checks, weld seam integrity tests, mat stitch tensile verification, 200-hour salt spray corrosion testing, dynamic load fatigue tests, drop-impact testing, and pre-shipment box drop audits.
We provide comprehensive private label engineering: custom frame dimensions (6ft, 8ft, 10ft, 12ft, 14ft, 16ft, or rectangular 6x9ft to 8x11ft formats), customizable safety enclosure netting colors, silk-screened brand logos, custom handle bar configurations, and e-commerce drop-test certified mail-order packaging.
Professional gymnastics clubs require trampolines featuring high-rebound mats, reinforced heavy-wall steel frames (up to 2.5mm tube thickness), and oversized safety padding. Funjump's rectangular trampoline series engineered with 8x11ft footprints offers the predictable, straight bounce lines essential for elite gymnastic acrobatics and routine training.
Commercial venues require durable high-throughput products with maximum safety protection. Our curved pole enclosure systems wrap 10mm thick EPE shock-absorbing foam around all metal supports, maintaining a continuous 360-degree internal safety barrier that prevents jumper collision with frame uprights.
Adult rebounder workouts demand silent operation and joint-friendly kinetic return. Funjump's 51" foldable fitness trampolines with T-bar adjustable handrails feature premium elastic bungee systems that deliver ultra-quiet, low-impact cardio workouts for home gyms and commercial group studios.
For toddlers (ages 3–6), safety takes total precedence. Our 55" indoor mini-trampolines feature springless design architectures, soft high-density mesh nets, double-zipper U-shaped doors, and padded floor feet to enhance motor skills and core balance safely in early learning environments.
Take a virtual walkthrough of our 68,000 m² specialized industrial workshops, from raw steel tube bending to sewing, packing, and warehousing.
Our dedicated internal testing laboratory executes real-time quality control checks to guarantee absolute compliance with international consumer safety standards.
A closer look at our globally popular customized trampoline lines across international e-commerce platforms like Amazon, eBay, and specialized B2B fitness distributors.
Available in diameters from 6 feet to 16 feet, this customizable round outdoor trampoline prioritizes multi-user safety and durable elastic energy transfer. Woven with 8 rows of precision sewing on a 260g UV-resistant PP jumping mat, it is supported by high-strength galvanized steel springs and heavy-duty U-shaped legs capable of sustaining static loads up to 150 kg.
Engineered for enhanced safety, the curved enclosure pole system keeps the 360-degree safety net extended away from the metal poles. Covered with 10mm thick EPE protective foam, it prevents direct impact during high-energy acrobatic jumps, making it a top choice for family backyards and interactive play.
Built with 48 high-strength zinc-plated springs and comprehensive anti-corrosion frame protection. This all-weather trampoline is designed to withstand extreme freeze-thaw cycles and sun exposure, ensuring long-lasting performance for outdoor residential yards.
Specially designed for children aged 3 to 6, this 55-inch mini indoor trampoline features a springless design utilizing high-density elastic ropes. The fully enclosed mesh netting and U-shaped zipper door offer parents complete peace of mind during indoor play.
