Explore our precision-engineered indoor toddler rebounders, outdoor family trampolines, and custom commercial play structures built to exceed international safety standards.
In the rapidly evolving juvenile play equipment market, safety engineered through rigorous mechanical verification is no longer optional—it is the baseline. Zhejiang Lingsha Technology Co., Ltd. (Funjump) operates as a globally recognized, high-tech manufacturing leader specializing in full-spectrum trampoline solutions. From 55-inch indoor toddler trampolines featuring springless safety systems to heavy-duty commercial outdoor installations spanning 6ft to 16ft, our engineering paradigm synthesizes structural biomechanics, advanced material science, and lean automated manufacturing.
Our enterprise infrastructure spans over 68,000 square meters of state-of-the-art production floors, backed by an elite workforce of over 100 specialized technicians and automated robotic systems. Operating with a daily output capacity exceeding 1,500 complete trampoline sets, Funjump empowers top-tier global brands, e-commerce leaders on platforms like Amazon, and international distributors with robust OEM/ODM services, custom design capabilities, and zero-defect compliance assurance.
Indoor child trampoline design presents unique engineering challenges: minimizing impact deceleration stress on developing pediatric skeletal structures while guaranteeing structural immobility and complete pinch-point isolation. Unlike standard adult rebounders or oversized yard trampolines, toddler indoor units require meticulous elastic modeling.
Traditional metal helical springs pose severe pinch risks for small digits and deliver high peak recoil forces unsuitable for toddlers aged 3–6. Funjump indoor units utilize high-elasticity synthetic latex bungee cords engineered for linear force-displacement curves. This delivers a smoother, deeper rebound that absorbs impact kinetic energy gently.
Our patented inner-net enclosure mechanism sews the high-density polyethylene (PE) safety mesh directly to the jumping mat polypropylene (PP) weave. This completely eliminates feet entrapment gaps near the frame margin, preventing severe ankle twists or contact with structural uprights.
Featuring low-center-of-gravity U-shaped base legs cold-rolled from heavy-gauge galvanized structural steel tubing (1.5mm to 2.0mm wall thickness), our frames resist tipping under extreme lateral dynamic loads. Non-marking anti-skid rubber feet isolate vibration and protect residential floor surfaces.

Located in the heart of China’s hardware and manufacturing hub (Zhejiang), Zhejiang Lingsha Technology Co., Ltd. (Funjump) embodies the competitive edge of modern Industry 4.0 production ecosystems. Supply chain resilience, cost efficiency, and batch-to-batch consistency stem from our continuous capital investment in automated processing equipment.
Our metalworking workshops utilize automated CNC laser pipe cutters, hydraulic automatic benders, and robotic arc welding arms. By eliminating human variability in seam welding and tube punching, frame structural joints exhibit zero stress concentrations and zero burrs, maximizing long-term fatigue strength under repeated cyclic loads.
Safety net enclosures and jumping mat assemblies require high tensile integrity. Our textile sewing division features computerized multi-needle sewing machines operating with heavy-duty UV-stabilized V-92 bonded polyester thread. Eight parallel rows of lockstitching lock the triangular spring V-rings permanently into place.
We believe enterprise procurement decisions must be backed by transparent physical infrastructure verification. Funjump welcomes global client audits. Below is a detailed visual tour across our specialized production workshops and internal Quality Control (QC) safety laboratory.
Equipped with heavy CNC punching machines, high-speed automated pipe cutters, and hydraulic bending rigs to process premium galvanized steel tubes into rigid trampoline frame chassis.
High-speed computerized lockstitch machinery producing UV-resistant polypropylene jumping mats, multi-layer outer boundary safety pads, and tear-resistant net enclosures.
Automated carton packaging, drop-test verified mail-order box reinforcement (ISTA 3A standard), and large-capacity high-bay warehousing ensuring rapid container loading.
Every batch undergoes severe stress testing: static weight load testing (up to 500kg), dynamic spring fatigue cycles (>100,000 bounces), UV aging acceleration chamber testing, and salt spray rust analysis.
As consumer expectations evolve toward quick storage solutions, smart interactive play, and eco-friendly manufacturing, Funjump’s R&D department is pioneering three major technological breakthroughs:
Traditional fitness and indoor trampolines suffer from high assembly friction and tedious maintenance. Based on customer feedback, our engineering team has patented a push-button self-locking joint structure. Users can fold or deploy a 40-51 inch mini trampoline in under 30 seconds without requiring wrenches, retaining 100% frame rigidity during play.
Integrating MEMS motion sensors directly beneath the jumping mat structure to track jump frequency, height, and calorie expenditure. Syncing via Bluetooth to interactive gaming apps, transforming solitary jumping into gamified physical therapy and active entertainment for young children.
Transitioning to 100% recyclable thermoplastic polyurethane (TPU) elastic elements and zero-VOC electrostatic powder-coated metal surfaces. Guaranteeing zero chemical off-gassing (BPA-free, Phthalate-free, Lead-free), aligned with strict EU REACH directives.
Navigating international regulatory landscapes is vital for global importers, brand owners, and commercial retail chains. Funjump holds pre-certified documentation across all major consumer safety jurisdictions, streamlining customs clearance and reducing risk for enterprise buyers.
Our kid trampolines comply strictly with ASTM F381-16 (Standard Safety Specification for Components, Assembly, Construction, and Use of Consumer Trampolines) and ASTM F2225-15 (Standard Safety Specification for Trampoline Enclosures). All foam padding materials pass CAL 117 flammability tests.
Products exported to Europe hold TÜV GS (Geprüfte Sicherheit) marks and CE / EN71-14 certification (Safety of Toys - Trampolines for Domestic Use). Chemical safety is verified by independent lab testing (SGS/TÜV/Intertek) covering Heavy Metals, PAHs, and Phthalates.
