Product Description

The Mid-Back Mesh Swivel Task Chair with Fixed Arms, model OC-MB-MESH-0620-GRY, presents a practical office seating solution with a clean grey and black appearance. Its grey flexible polymer mesh back is tensioned within a rounded black or dark-grey moulded polymer frame, creating a ventilated visual profile suited to everyday work settings. The light-grey woven fabric seat is upholstered with a tailored edge seam and paired with fixed black polymer T-shaped armrests. A five-star black polymer base, chrome-plated steel gas lift, and twin-wheel casters complete the straightforward commercial look. Construction balances cushioned support with durable support components. The seat uses a polyurethane foam core with a softer top layer, giving a finished cushion thickness of 90 mm, while the backrest includes a curved padded or mesh-supported lumbar section integrated into the lower back. Beneath the seat is a moulded plywood or polymer carrier, a black steel tilt mechanism, and a 50 mm chrome-plated telescopic cylinder with a black outer shroud. The arm pads are stationary and mounted on polymer support stems, and the chair rolls on nylon twin-wheel casters. Functionality is focused on typical desk tasks. A pneumatic side lever adjusts seat height through 100 mm of travel, from 430 to 530 mm, and the chair rotates through 360 degrees. The synchronous-style back recline reaches a 12-degree maximum tilt angle, with a one-position upright lock and a tension knob for backward resistance suitable for users up to 120 kg. Fixed armrests provide consistent forearm support, while the five-point base and casters allow movement in all directions. This unbranded task chair fits open-plan workstations, home offices, hot-desking areas, meeting or training rooms, and reception workstations involving rotating seated tasks. It is intended for pairing with 760 mm-high desks and work surfaces at least 600 mm deep, and the residential rolling footprint is noted as 610 mm. Buyers should plan for assembly, with a reference time of 40 minutes per set, and note that the product is supplied as one set across two cartons with a packaged gross weight of 23 kg. Clear width between armrests is 540 mm, making desk clearance and user size important specification checks before procurement.
