Product Description

The Gray Mesh Ergonomic Office Chair is a high-back task seating solution with a clean, neutral appearance suited to professional and domestic workspaces. Its open gray mesh back follows a framed curved carrier, while the matching mesh-faced seat is supported by a molded edge and gray polymer shell. A curved padded lumbar section sits behind the back mesh, providing a defined support zone without interrupting the chair’s streamlined look. Matte molded arm pads, light gray painted aluminum uprights, a polished aluminum five-star base, and black twin-wheel casters complete the visual composition. Between the armrests, the clear width is 540 mm; the seat cushion is 90 mm thick and the backrest padding is 70 mm thick. The lumbar support zone is 240 mm high. Construction combines breathable polyester mesh, molded polymer components, painted and polished aluminum, a steel gas lift, and black nylon casters. These materials give the chair a lightweight commercial feel, with a net weight of 16.5 kg, while the polished five-star base provides a structured foundation. The chair is rated for a recommended user weight of 136 kg. Its static test ratings include a 680 N backrest proof load and a 1600 N seat proof load. Durability references include 100,000 caster rolling cycles, 100,000 gas-lift height-adjustment cycles, and 120,000 recline cycles. Functional adjustment is centered on routine office comfort. A side lever operates the pneumatic seat-height lift, which adjusts from 450 to 540 mm. The under-seat synchronized tilt mechanism allows the backrest to move through 24 degrees, from 94 to 118 degrees, and includes tension adjustment. The arm pads offer 70 mm of vertical travel, helping users align support for keyboard work or reading. A 360-degree swivel seat and five 60 mm twin casters support easy movement around standard workstations. This model is appropriate for open-plan office desks, home offices, hot desks, shared meeting spaces, and compact study areas. Its gray finish coordinates with restrained commercial interiors, while the breathable back and adjustable features support daily computer use. Buyers should note that the unbranded chair is supplied as one set in two cartons, with a packaged gross weight of 23 kg and a reference assembly time of 40 minutes. Carton dimensions are 850 by 420 by 720 mm, with 0.26 cubic meters per set, making the packaging details useful for receiving, storage, and freight planning.
