Engineered for the Human Body, Built for the Enterprise.
Every LONGTENG chair begins with a biomechanical study of posture, pressure distribution, and micro-movement during long working hours. We do not treat ergonomics as a marketing label — it is a measurable engineering discipline that drives every contour, joint, and material decision.
Our design teams work from 3D motion-capture data collected from real office environments, translating spinal alignment patterns and forearm pressure maps into adjustable structural mechanisms. The result is a seating family that adapts to the user rather than demanding the user adapt to it.
From entry-level task chairs to executive leather seating, every model is validated to ANSI/BIFMA X5.1 structural standards and CAL117 fire retardancy, ensuring both comfort integrity and regulatory readiness for North American commercial deployment.
High-Elastic Mesh Back
Proprietary Korean elastomeric mesh distributes lumbar and shoulder pressure across a tension matrix, maintaining airflow and structural shape across 100,000+ impact cycles.
Multi-Dimensional Adjustability
Up to 6D armrests, adaptive lumbar depth, synchronized tilt tension, and 4-position recline lock — each axis independently tuned for extended 12+ hour workdays.
Die-Cast Aluminum Architecture
368 high-strength aluminum alloy star bases tested to 1,350 kg static load, paired with sealed PU silent casters for archival flooring and open-plan acoustics.
Commercial-Grade Materials
Cold-cure molded foam, commercial wool-blend upholstery, and low-VOC adhesives selected for 24/7 enterprise deployment and indoor air quality compliance.
Precision Engineering for the Modern Shower Experience.
Our shower systems are designed as complete bathing solutions, not simple fittings. Every rainfall head, handheld spray, valve body, and diverter is engineered to deliver consistent high-pressure performance and long-term reliability in hospitality-grade bathrooms.
We work directly with project engineers and hospitality buyers from specification through installation. Modular shower head sizes, interchangeable shower arm lengths, and multi-function valve options allow a single SKU family to adapt across thousands of real-world bathroom layouts without custom tooling.
Every unit is built from high-quality 304 stainless steel and brass valve bodies, finished to resist daily scratches, corrosion, and tarnishing in humid shower rooms, and tested to NPT 1/2" standard plumbing connections for straightforward North American installation.
High-Pressure Rainfall Heads
12" / 10" / 8" ultra-thin 304 stainless steel rain shower heads with silicone nozzles deliver a full-body spa-like cascade even in low-water-pressure areas.
Push-Button & Diverter Valves
2-in-1 and 3-in-1 push-button diverter valves let users switch between rainfall, wall-mount and handheld spray with a single press — simple, precise, and intuitive.
Brass Valve Body Construction
Solid brass mixing valve cores and 304 stainless steel housings resist corrosion, scale, and daily wear, maintaining stable temperature and flow across 500,000+ cycles.
NPT 1/2" Standard Connections
All systems comply with NPT 1/2" thread plumbing connections and ship with detailed installation instructions for fast, code-compliant US installation.
Transparent Supply Chain Flow
From raw material fabrication on the mainland to final port delivery across North America, our synchronized pipeline ensures total accountability at every stage.
Zhejiang & Hebei Factories
Precision manufacturing, CNC cutting, component assembly, and initial structural testing under strict ISO guidelines.
QC & Testing Lab
Rigorous stress tests, cyclic durability evaluations, fire retardancy checks, and dimensional verification before dispatch.
Hong Kong Export Hub
Container consolidation, customs clearance documentation, commercial invoicing, and secure vessel booking.
US Ports (FOB / CIF / DDP)
Reliable ocean freight delivery to Long Beach, Los Angeles, New York, or direct warehousing via flexible trade terms.
Quality & Compliance
We adhere strictly to international testing protocols and regulatory requirements, ensuring hassle-free commercial importation and long-term asset reliability.
BIFMA X5.1 / ANSI
Our ergonomic office chairs undergo rigorous drop tests, swivel endurance trials, and backrest strength assessments to meet strict American National Standards.
CAL117 Fire Retardancy
Upholstery fabrics and high-density foam padding comply with California Technical Bulletin 117 standards for flame resistance in commercial environments.
ISO 9001 Factory Certification
All partner manufacturing facilities operate under certified Quality Management Systems, ensuring consistent batch quality and traceable production logs.
HS Code Alignment
Precise Harmonized System code classification for office furniture and plumbing fixtures to prevent customs delays and ensure accurate duty calculations.
Full Commercial Invoice & Packing List Support
Our trade desk provides comprehensive shipping documentation including Commercial Invoices, detailed Packing Lists, Bills of Lading, Certificates of Origin, and Mill Test Reports to support seamless US customs entry and corporate auditing.
