Product Description

The Mesh Ergonomic Office Chair with Headrest and Adjustable Arms, model ERG-MESH-HR-650, is a high-back task chair offered without a branded label. Its appearance combines blue elastic mesh with a light-gray molded frame, creating a clean, contemporary silhouette suited to modern interiors. The tall back, contoured headrest, compact seat, and five-star base establish a practical office profile, while twin-wheel casters give the chair a mobile, task-oriented stance. Overall dimensions are 680 by 680 by 1240 mm, with 540 mm of clear width between the armrests. The seat cushion thickness is 90 mm, the backrest padding thickness is 70 mm, and the lumbar support zone height is 240 mm. The back and seat use blue woven elastic mesh stretched over molded carriers. The headrest uses matching blue mesh over a curved padded insert. A molded light-gray polymer seat pan forms the seat carrier and integrates the side frame, while the back is supported by a light-gray molded polymer outer frame. The arm supports use matching light-gray stems with dark-gray padded arm caps. A black steel gas-lift column, black tilt mechanism, visible adjustment lever, nylon five-star base, and twin-wheel casters complete the construction. Functionally, the chair is designed for flexible seated work. Pneumatic seat-height adjustment provides 90 mm of travel, from 450 to 540 mm. The synchro-tilt mechanism allows the backrest to recline to 122 degrees, with a rear tension knob for changing recline resistance. An under-seat control provides a three-position back-angle lock and release. The curved headrest is mounted on twin posts and intended to support rear head and neck alignment. The breathable mesh back and lumbar zone make the chair appropriate for extended computer work, while the padded arm caps add resting comfort. This model is well suited to open-plan office workstations paired with desk heights from 450 to 540 mm, as well as home offices or studies used by a single person up to 185 cm tall. Its 680 mm footprint and caster mobility are useful where floor space needs to remain clear. The recommended user weight capacity is 135 kg. Procurement planning should account for final assembly and delivery handling: one set ships in two cartons, with a reference assembly time of 40 minutes. The package information lists a gross weight of 23.5 kg, packaged gross weight of 23 kg per set, and carton volume of 0.26 cubic meters per set. Buyers should also review seat-height compatibility with existing desks, floor surface suitability for casters, and the need for coordinated blue mesh and light-gray framing within the planned interior.
