Product Description

The Mid-Back Mesh Swivel Task Chair presents a clean, functional office seating profile defined by a black mesh back, olive-green padded seat, fixed T-shaped armrests, and a matching five-star caster base. Its mid-height back is centered around a perforated black polymer lumbar panel, while the flexible woven mesh is stretched within a molded polymer frame. The contrasting seat and back create a restrained visual identity suited to practical work environments without dominating the surrounding workspace. A 540 mm clear width between the armrests gives the chair an open seating layout, and the swivel center column supports easy turning at a desk. Construction combines upholstered comfort with durable support components. The seat uses 70 mm molded polyurethane foam upholstered in olive-green woven fabric, with a finished cushion thickness of 90 mm. A 12 mm molded plywood or polymer seat board is concealed beneath the cushion. The backrest includes 70 mm of padding thickness and a 240 mm high lumbar support zone. Armrests are fixed black polymer T-posts with padded top surfaces. Mobility is provided by nylon twin casters on a plastic five-star base, while height adjustment uses a chrome-plated steel lift tube and black painted steel telescopic column. The chair is rated for users up to 120 kg and has a net weight of 12.5 kg. Daily operation is managed through a pneumatic lever with a 100 mm height-adjustment stroke and a 540 mm maximum seat height. The recline mechanism allows rearward tilt to 12 degrees and includes a one-position upright lock; the recline reference also notes a 125-degree setting with suggested lock positions. A rotary paddle adjusts tilt tension for users within the stated weight capacity. Swivel movement, rolling casters, and the breathable mesh back make the chair suitable for open-plan desks, computer workstations, administrative areas, training rooms, and home offices. The 540 mm maximum seat height is intended for use with standard 760 mm desks. Procurement teams should note that each set is supplied in two cartons, with a packaged gross weight of 23 kg per set and a reference carton volume of 0.26 cubic meters per set. The stated carton dimensions include 650 x 590 x 360 mm and 850 x 420 x 720 mm, allowing receiving and storage space to be planned in advance. Assembly time is referenced at 40 minutes per set. The model is an unbranded office chair, MBM-OC-590-980, making it best suited to projects prioritizing straightforward task seating, coordinated installation, and neutral commercial aesthetics rather than bespoke branding or specialized executive seating.
