Product Description

The YUXIANG ERG-MESH-HB700 is a high-back ergonomic mesh office chair designed to balance supportive comfort, professional aesthetics, and long-term durability for varied seating environments. Its sleek, functional silhouette features a tall, contoured mesh backrest paired with a generously padded seat, aligned to maintain neutral posture during extended seated use. The polished aluminum alloy five-star caster base forms a stable, streamlined foundation, with soft dual-wheel casters mounted to each point of the base to enable smooth, unobtrusive movement across flooring surfaces. The chair integrates an adjustable headrest and height-adjustable armrests into its frame, creating a cohesive visual profile that fits both formal and casual workspace layouts.
Constructed for sustained daily use, the chair’s backrest uses breathable woven polyester mesh stretched over a 1.5mm thick welded steel tubing inner frame, with an integrated structured mesh tension zone built in to deliver targeted mid-back lumbar support. The seat cushion features a molded high-density polyurethane foam core wrapped in wear-resistant polyester fabric, paired with soft padded polyurethane armrest pads for comfortable upper body support. The central gas lift cylinder is made of chrome-plated steel, while casters use polyurethane rolling surfaces set on nylon hubs to withstand repeated use over time.
Core functional features are engineered to adapt to diverse user needs: lever-activated seat height adjustment operates via a Class 3 gas lift to deliver a 105mm vertical stroke, while the backrest offers a 125° maximum tilt angle with 3-position lock and a knob-controlled tilt tension adjustment calibrated to match user body weight. The headrest offers 30mm vertical height adjustment with fixed tilt, the chair supports unrestricted 360-degree swivel rotation around its central axis, and armrests adjust vertically to suit individual seating preferences. The breathable mesh back reduces heat buildup during long periods of use, and the durable build supports a maximum user weight of 181 kg.
This chair is well-suited for a wide range of commercial and residential spaces, including open plan office workstations, home office setups paired with standard 760mm height desks, executive private offices, conference meeting rooms, shared hot-desking spaces, and call center environments requiring seating for long shifts. Its adjustable components accommodate a broad range of body types, while its professional appearance fits seamlessly across formal and collaborative workspace designs.
For procurement planning, each chair ships in two cartons, with a packaged gross weight of 23 kg per set, and requires an 40 minutes of assembly per unit. Bulk shipping calculations show 135 sets can be loaded into a 20GP container at 85% space utilization, supporting efficient large-volume order fulfillment for office fit-outs, commercial furnishing projects, or residential workspace upgrades. The chair’s abrasion-resistant mesh and durable casters are engineered to withstand the high traffic of shared work environments, reducing long-term replacement needs for high-use seating deployments.
