Product Description

The mid-back grey mesh ergonomic office chair pairs a clean two-tone aesthetic of neutral grey and crisp white with a purpose-built layout tailored for extended seated use. The fixed armrests sit flush with the seat structure, creating a streamlined silhouette that avoids visual clutter across uniform seating deployments. Constructed with a glass-fiber reinforced plastic white frame that forms both the backrest support and five-star base, the chair balances lightweight handling with structural resilience. The backrest uses breathable woven polyester mesh stretched over the frame, with an integrated fixed Y-shaped lumbar support molded to align with the natural spinal curve. The seat features a high-density cold-cured polyurethane foam core wrapped in stain-resistant woven polyester fabric, supported by an internal plywood board, with soft polyurethane pads topping the fixed glass-fiber reinforced armrest supports. Double-wheel black nylon casters attach to the reinforced nylon base, paired with a chromed steel gas lift cylinder for height adjustment. The chair supports full 360-degree swivel rotation, controlled via a central joint between the seat and base. A side lever operates the pneumatic height adjustment, allowing users to set seat position to fit individual desk heights. The synchro-tilt mechanism enables a maximum 12-degree backward recline with an upright lock option, and an under-seat knob lets users adjust tilt tension to match their preference for support during movement. Fixed armrests deliver consistent, stable forearm support, while the dual-wheel casters enable smooth rolling across both hard flooring and carpeted surfaces. This model fits a broad range of commercial and residential spaces, including open-plan office workstations for daily 8-hour use, compact home offices and study areas, conference and meeting rooms, high-traffic co-working facilities, professional reception zones, and interactive training or classroom settings. For procurement teams, key considerations include packaging split across two cartons per unit, with an assembly time per chair; the chair’s compact footprint supports high-volume loading for large orders. The neutral finish allows consistent alignment across mixed space layouts without clashing with existing interior palettes, and the durable construction holds up to regular use by rotating occupants in shared environments.
