Explore our flagship OEM/ODM trampoline systems, engineered for maximum structural safety, ultra-quiet performance, and compact storage scalability.
As urban living spaces shrink and health-conscious consumer segments expand globally, the demand for high-performance, compact, and ultra-quiet indoor fitness equipment has reached an all-time high. Foldable indoor trampolines (rebounders) are no longer merely children's toys—they are sophisticated biomechanical exercise devices utilized in home gyms, rehabilitation centers, and boutique fitness studios.
The global rebounder market is experiencing a compound annual growth rate (CAGR) driven by low-impact lymphatic drainage exercises, high-intensity interval training (HIIT), and space-saving furniture trends in North America, Europe, and East Asia. Commercial B2B buyers now prioritize rapid folding mechanisms that preserve frame tension over thousands of usage cycles.
Traditional springs are rapidly being replaced by multi-strand latex elastic cords (bungees). These components deliver a smoother deceleration curve, reducing joint shock on knees and spine by up to 85%. Modern manufacturing demands strict adherence to ASTM F381-16 and EN 71-14 safety norms for indoor environments.
End-user friction typically stems from complex setup processes. B2B importers are shifting orders toward custom foldable indoor trampolines featuring pre-assembled hinge joints, drop-lock pins, and snap-fit handlebar systems that require zero external tools for setup or disassembly.
Trading under the globally recognized brand Funjump, Zhejiang Lingsha Technology Co., Ltd. operates a state-of-the-art manufacturing campus designed for scale, quality, and complete compliance with international market standards.
Spanning over 68,000 square meters and powered by more than 100 dedicated technical specialists and automated robotic welding cells, Funjump delivers a daily output exceeding 1,500 complete trampoline sets. Our enterprise holds verified certifications including ISO9001, BSCI, GS, EN71-14, ASTM, and AS4989.
Unlike standard assembly shops, our facility houses an independent, specialized trampoline safety testing lab. Professional QC inspectors subject raw materials and finished frames to rigorous static load testing, dynamic fatigue cyclic testing, and salt-spray corrosion tests to eliminate structural defects long before shipment.
At Zhejiang Lingsha Technology Co., Ltd., we believe that a truly superior product is refined through active market feedback. Historically, the global fitness market faced a major trade-off: easy-to-store trampolines often lacked structural rigidity, while stable trampolines were cumbersome to assemble and store. Adding mobile joints often compromised frame stiffness, causing wobble and premature metal wear.
Through aggressive R&D, Funjump engineers developed a patented quick-folding frame matrix paired with self-locking safety pin connectors. This breakthrough enables our 40-inch to 51-inch foldable fitness rebounders and mini indoor trampolines to fold into a quarter of their operational footprint in seconds, without tools, while maintaining zero frame deflection under heavy load capacity (up to 150 kg / 330 lbs).
This design victory has positioned Funjump as a top supplier for leading international brands and top-ranking seller stores on major global e-commerce platforms such as Amazon, Walmart, and specialty fitness distributors worldwide.

| Feature Parameter | Funjump Custom Foldable Series | Generic Market Rebounders | B2B Advantage / Information Gain |
|---|---|---|---|
| Frame Material | Heavy-duty galvanized steel (1.5mm–2.0mm wall thickness) | Standard cold-rolled thin steel (<1.2mm) | 300% higher deformation resistance & zero rust |
| Folding Hinge Tech | Patented Quad-Fold with auto-locking safety pin system | Single bi-fold without secondary locks | Prevents accidental snap-backs during storage/use |
| Suspension System | High-density latex bungee ropes / Calibrated springs | Low-grade steel tension springs | Whisper-quiet operation (<40dB); superior shock absorption |
| Jumping Mat Construction | 260g UV-resistant PP mat with 8-row perimeter stitching | Standard 180g PP mat with 4-row stitching | Prevents edge tearing under continuous dynamic loads |
| Handlebar System | T-Bar with 4-level height adjustment & dual locking knobs | Fixed straight bar or single pin adjust | Ergonomic versatility for users 110cm to 195cm tall |
Quality at Funjump is not an afterthought—it is engineered into every stage of production. Our dedicated QA team conducts multi-point physical inspections before any package leaves the warehouse floor.
Every batch of bungee cords and steel springs undergoes 100,000 continuous stress cycles to measure elasticity retention and fatigue points.
Frames are subjected to 500kg static load testing to ensure zero structural deformation or weld cracking under maximum weight thresholds.
High-magnification optical scanners inspect polypropylene mat V-rings and webbing seams to verify 8-row stitch integrity.
Metal leg tubes, hinges, and hardware are tested in a salt fog chamber for 72 hours to guarantee rustproof lifespan in damp environments.
Whether you are an established fitness brand, a fast-growing Amazon FBA merchant, or a regional sports equipment wholesaler, Funjump provides end-to-end OEM and ODM capabilities to power your growth.
Customize frame color, bungee resistance levels (soft bounce vs. intense workout), foam handle padding, safety pad printing, and branded user manuals. We support complete private label packaging tailored to your brand identity.
Drop-ship and Amazon FBA ready. Our compact inner box engineering reduces volumetric dimensional weight by up to 35%, drastically lowering transoceanic freight and last-mile delivery costs for online retailers.
Located near Ningbo and Shanghai ports, we guarantee flexible trade terms including EXW, FOB Ningbo, and CIF. Our logistics team handles full customs documentation, certificate clearance, and container optimization.
Find fast answers to common purchasing, engineering, and factory partnership questions.
We support Ex Works (EXW), FOB Ningbo, and CIF shipping terms. Our standard payment schedule is T/T (Telegraphic Transfer): 30% advance deposit paid prior to production commencement, with the remaining 70% balance settled against presentation of the Bill of Lading (B/L) copy.
Sample evaluation orders are typically processed and dispatched within 5 to 7 business days. For mass purchasing: Peak Season (November to June) lead time ranges between 35 to 55 days; Off-Peak Season (July to October) lead time ranges between 10 to 35 days depending on order volume and customization complexity.
Our standard Minimum Order Quantity (MOQ) is 50 sets per individual size or specification. Sample orders and trial batches for new brand evaluation are welcome prior to committing to full mass orders.
We provide a 1-Year Structural Warranty covering steel frames, hinges, and weld joints against manufacturing defects. (Note: Warranty policy excludes damage resulting from product misuse, physical accidents, or improper outdoor exposure for indoor models).
Yes, we provide product samples for engineering evaluation and market testing. While the sample product unit can be provided free of charge under qualification, the buyer is responsible for covering international express freight charges.
Noise is primarily eliminated at two points: First, we replace metal-on-metal springs with continuous latex bungee loops wrapped in friction-resistant nylon sheath. Second, the leg tubes feature custom TPR (Thermo-Plastic Rubber) suction footpads that isolate vibration from hard floors, reducing noise to below 40 decibels.
From mini indoor rebounders to heavy-duty outdoor recreational systems, select from our fully certified manufacturing lines.
