Product Description

The Mid-Back Mesh Swivel Office Chair with Fixed Arms, model MBM-GRY-01, is a practical gray task chair designed for everyday desk use in both commercial and residential settings. Its coordinated light gray frame, mesh back, gray upholstered seat, and black gas lift create a clean, understated appearance that integrates well with neutral office interiors. The chair uses a five-star support base with radial legs and twin-wheel casters, while the one-piece molded frame forms continuous loop armrests and back side rails. The fixed arms define a structured seating area and offer stable forearm support without width, height, or pivot adjustment. Overall dimensions are 630 by 640 by 1040 millimeters, with 540 millimeters of clear width between the armrests. The mid-height back includes a 240-millimeter lumbar support zone, helping maintain a conventional task-chair profile suited to standard workstations. Construction balances comfort, support, and manageable weight. The backrest uses light gray woven polyester mesh tensioned within a molded polymer frame, allowing the back to remain visually open during seated use. The padded seat is upholstered in gray fabric and features a molded polyurethane foam core, with finished seat cushion thickness of 90 millimeters and foam density specified at 45 kilograms per cubic meter. Beneath the cushion, a molded polymer seat pan sits over a steel tilt mechanism plate. A black 50-millimeter-diameter steel gas-lift cylinder with a polymer telescopic cover connects the seat to the gray molded or coated five-star base. The product has a recommended user weight capacity of 120 kilograms and a net weight reference of 12.5 kilograms. Functionality is centered on flexible desk movement and basic ergonomic adjustment. An under-seat lever operates the pneumatic seat-height lift, which provides a 100-millimeter stroke for adapting to different desk and user requirements. The multi-position synchro tilt offers a 15-degree back recline, a lock function, and tension adjustment. Swivel access and the five-point caster layout support omnidirectional movement and braking-free rolling on office floors, making the chair easy to reposition during computer work, collaboration, or shared-desk use. This model is well suited to open-plan office workstations, particularly daily computer tasks at 760-millimeter desks. Its neutral gray fixed-arm mesh design also fits hot desks, meeting rooms, administrative areas, and shared workspaces used by rotating occupants. For home offices, study rooms, or residential work areas, it offers a commercial task-chair format without a bold visual statement. Buyers should plan for assembly and logistics: each set is supplied in two cartons, with a reference assembly time of 40 minutes, packaged gross weight of 23 kilograms, and carton volume of 0.26 cubic meter per set. A 20-foot container loading reference is 212 cartons. Procurement decisions should also account for the fixed arm design, mesh back, fabric seat, swivel base, caster mobility, and the stated tilt and height-adjustment features, ensuring the chair matches the intended desk type, flooring, user mix, and shared-workplace requirements.
