Zhejiang Lingsha Technology Co., Ltd. (Funjump) stands at the forefront of modern recreational and athletic equipment manufacturing. Specializing in high-precision OEM and ODM production, Funjump is dedicated to engineering safe, stable, and highly durable trampolines customized to stringent global specifications. Our product matrix spans across indoor and outdoor small square trampolines, specialized toddler units, commercial fitness rebounders, and large-scale backyard play systems.
Rooted in rigorous quality control, our production methodologies satisfy international compliance benchmarks, including ISO9001, BSCI, GS, EN71-14, ASTM F381/F2225, and AS4989. Our state-of-the-art facility features an integrated, specialized trampoline testing laboratory staffed by certified engineering inspectors to systematically eliminate structural defects before products leave the factory floor.
In the global market for home fitness and juvenile play gear, the small square trampoline represents a major leap forward in frame dynamics and spatial efficiency. Unlike traditional round trampolines—which guide the jumper toward the center mat via uniform radial spring tension—square trampolines feature independent spring rows along orthogonal axes. This fundamental difference transforms both performance and engineering requirements.
Square frames experience severe torsional loads at their 90-degree junctions. Funjump solves this using robotically welded, cold-drawn carbon steel corner joints reinforced with gusset plates. This keeps the frame rigid and prevents metal fatigue during high-frequency vertical impacts.
Because the springs pull at right angles rather than radially, the mat offers a consistent, predictable bounce across its entire area. This smooth vertical response makes square models ideal for athletic training, physical therapy rebounders, and space-constrained indoor play areas.
Square geometry eliminates the wasted corner space typical of round trampolines, making efficient use of urban indoor rooms. B2B buyers also benefit: square components pack tightly into shipping containers, maximizing volumetric efficiency and lowering per-unit freight costs.

| Frame Steel Spec (Galvanized) | 1.8mm - 2.5mm Heavy-duty Tube | 1.2mm - 1.5mm Standard Tube | 1.0mm - 1.4mm Lightweight Tube |
| Spring / Bungee System | High-tensile Tapered Springs / Bungees | Helical Steel Springs | Basic Elastic Straps or Springs |
| Container Load Factor (40' HQ) | High (Flat-pack optimized geometry) | Moderate (Arcuate curved tubes) | High (Small individual cube size) |
| Primary Target Market | B2B Brands, Urban Home, Indoor Gyms | Suburban Outdoor Residential | Personal Fitness & Boutique Studios |
We actively adapt to client feedback and real-world market demands. Traditional trampolines are often difficult to assemble, store, and ship. Funjump's engineering team solved these challenges by designing fast-assembly, tool-free locking joints and foldable mini-fitness trampolines—all while preserving full structural integrity.
Operating out of a 68,000-square-meter facility in Zhejiang, China, Funjump integrates metalworking, high-density sewing, precision packaging, and rigorous QC under one roof for complete quality control.
Our metal fabrication unit uses automated CNC pipe benders and robotic arc welders. Frame components undergo inner and outer hot-dip galvanization to ensure long-term rust prevention and structural safety under heavy loads.
High-density polypropylene (PP) jumping mats are reinforced with 8-row heavy-duty V-ring stitching using UV-resistant bonded nylon thread. Our safety enclosure nets use high-strength PE mesh to prevent tearing under impact.
Products are packed into drop-test certified 5-ply corrugated cartons. Each carton includes hardware blisters, color installation manuals, and protective foam inserts to prevent shipping damage during overseas transport.
Quality control is at the heart of Funjump's operations. Our laboratory tests every production batch for dynamic impact resistance, frame shear strength, spring fatigue limit (over 100,000 cycles), and chemical safety (phthalates/PAHs).
Entering international markets requires absolute adherence to regional safety standards. Funjump provides ready-to-import certification dossiers for major target regions worldwide, taking the complexity out of global procurement.
Our small square trampolines feature full perimeter enclosure netting, zero-gap mat-to-pad designs, and structural safety padding designed to meet strict US Consumer Product Safety Commission (CPSC) requirements.
TÜV Rheinland GS certification guarantees that components meet European mechanical safety standards, non-toxic REACH chemical limits, and heavy metals restrictions (EN71-3).
Built for high solar radiation climates, our outdoor models feature UV-stabilized jumping mats rated to 5,000+ hours of sun exposure, preventing premature breakdown under intense Australian UV rays.
Compact 45" to 55" square trampolines fit seamlessly into modern apartments, converting small indoor footprints into fun, active play spaces for growing kids.
Pediatric occupational therapists recommend controlled square rebounders with stability handrails to help children build balance, motor coordination, and core muscle tone.
Boutique fitness centers use foldable mini square rebounders with adjustable T-bars for low-impact, high-intensity cardio classes that are easy on joints.
