Product Description

The White Frame Grey Mesh Ergonomic Office Chair, model EOB-W38W-GY, is an unbranded high-back public and workspace seating solution defined by its clean two-tone visual profile. Its crisp white structural frame pairs with soft, neutral grey mesh and fabric surfaces to create a streamlined, contemporary silhouette, with a chrome-finished 5-star base that adds subtle polished contrast without disrupting minimalist space aesthetics. The chair’s open mesh back and padded fabric seat balance visual lightness with substantial structural presence, fitting seamlessly alongside both professional and casual workspace furnishing schemes. Constructed for long-term regular use, the chair features a tensioned breathable grey polyester mesh back supported by a white glass-fiber reinforced polypropylene frame. Its seat is built on a 12mm multi-layer plywood core, topped with molded 50kg/m³ high-density polyurethane foam with a 60% rebound rate, upholstered in abrasion-resistant woven grey polyester; finished seat cushion thickness measures 90mm, with 70mm of padding across the backrest. The headrest uses matching grey mesh set in a polypropylene frame, armrests mount to white powder-coated steel uprights topped with soft TPU pads, the 5-star base is 1.5mm thick chrome-plated steel, and 60mm dual-wheel casters feature a polyurethane wrap over a nylon core. The chair supports a maximum user weight of 150kg, suitable for users up to 180cm in height, with casters tested to 100,000 rolling cycles. Full functional adjustability supports sustained comfort across varied uses: a Class 3 gas lift enables 130mm of seat height adjustment via a right-side lever, paired with full 360-degree swivel. The backrest offers 14 degrees of tilt with a lock for the upright position, while the 2D headrest adjusts 60mm vertically and tilts 15 degrees. The 3D lumbar support, spanning a 240mm support zone, moves 70mm vertically and 30mm in depth to align with the lower back, and armrests adjust 80mm in height, slide forward and back, and rotate at the pad, with 540mm of clear width between armrests. Casters roll smoothly on hard floors and low-pile carpet. This chair is suited for private office workstations supporting 8 hours of daily use for administrative and professional staff, modern home offices, co-working shared spaces, conference rooms, and student or remote learner study rooms, pairing optimally with 2.4m executive desks. For procurement, note each unit ships in 2 cartons with a total packaged gross weight of 23kg and 0.26m³ total volume, allowing 135 sets to load in a 20GP container at 85% space utilization; assembly requires 40 minutes per set.
