Product Description

The YUXIANG EOCH-WF625high-back mesh ergonomic office chair blends structured modern styling with user-centered support for varied professional and residential work settings. Its two-tone white, blue, and grey color palette creates a clean, approachable visual profile: the white glass-fiber reinforced polypropylene frame, fixed curved white armrests, and white nylon composite five-star base create a light, cohesive structural base, paired with a blue breathable polyester mesh backrest, grey wear-resistant woven seat upholstery, dark mesh contoured lumbar pad, and blue fabric-covered padded curved headrest. The 700mm diameter five-star base supports smooth 360-degree swivel, with evenly spaced reinforced spokes and dual-wheel 50mm nylon casters for stable, unobtrusive movement across floor surfaces. Durable, thoughtfully selected materials deliver consistent long-term use: the seat core uses 70mm thick high-density molded polyurethane foam with a 60% rebound rate and 45 kg/m³ density, encased in woven fabric tested to 50000 Martindale abrasion cycles. Seams are stitched at 8 stitches per 30mm for secure construction, while the black powder-coated steel pneumatic gas lift enables reliable height adjustment. Core functional features support all-day seated comfort: a 100mm pneumatic seat height stroke accommodates adult users between 150cm and 190cm tall, while the butterfly tilt mechanism enables 25-degree backrest recline with secure lock positions. The 190mm high fixed non-slip armrests align with standard desk heights, the butterfly-shaped contoured lumbar pad matches the natural lower back curve, and the neck-height padded headrest reduces upper body strain. A rounded waterfall seat edge minimizes pressure on the backs of the thighs during extended work sessions. The chair supports a maximum recommended user weight of 136kg, with a net weight of 22kg for easy repositioning. This model fits a wide range of use cases: open-plan office workstations for 8-hour daily administrative and staff tasks, modern home office studies, small business meeting rooms where swivel function supports easy group interaction, flexible hot-desking zones that require frequent workstation shifts, and client-facing reception or consultation areas. For procurement planning, note each unit ships in 2 cartons with a total packaged gross weight of 23kg and 0.26 m³ total volume, requiring 40 minutes of assembly per set. 135 sets can be loaded in a 20GP container at 85% space utilization for bulk ordering, with fixed overall dimensions of 625mm wide, 660mm deep, and 1240mm tall to support space planning for target deployment areas.
