Product Description

The Mid-Back Mesh Swivel Task Chair with Fixed Arms is an unbranded office chair designed for practical daily seating in workstation, meeting, study and home-office settings. Its model is OFC-MB-MESH-FA-BLKBLU, presented in a blue and black color treatment that combines a breathable mesh back with a contrasting padded seat and black support components. Visually, the chair uses a mid-height backrest framed in black molded polymer, with blue woven flexible mesh forming the central support surface. The black upholstered seat has a rounded waterfall front and a molded foam cushion, while black fixed T-arms provide a structured, uncluttered side profile. A five-star nylon base, twin-wheel casters and chrome-plated gas lift with a black telescopic shroud complete the familiar task-chair form. The overall dimensions are 640 x 620 x 1010 mm, with a 540 mm clear width between the armrests. Construction balances comfort and utility. The seat cushion is 90 mm thick and uses 35 kg/m3 foam, while the backrest includes a 70 mm padded dimension and a 240 mm lumbar support zone. The back is connected to the seat mechanism by a curved polymer or steel-reinforced yoke, and height adjustment is handled by a chrome-plated steel gas lift. Under the seat is a black steel tilt plate with one visible operating lever, along with a tension control for recline resistance. The armrests are black molded fixed T-arms with flat polymer pads and vertical support posts; they do not adjust in height or width. Primary functions support flexible desk use. A right-side lever operates pneumatic seat-height adjustment through a 100 mm stroke, setting seat height from 440 to 540 mm. The gas-lift center enables 360-degree swivel movement, while the five-point base helps keep the chair centered during rotation. The tilt mechanism allows 19 degrees of back travel, from 93 to 112 degrees, and the tension knob lets users modify recline resistance. Five 60 mm twin-wheel casters provide rolling mobility across typical office seating arrangements. The suggested user body weight capacity is 120 kg, and the chair itself has a net weight of 14.5 kg. This model is well suited to open-plan office desks, computer workstations, administrative seating, conference rooms, training positions, study areas and home offices. It is especially appropriate where breathable back support, compact rolling movement, swivel access and fixed arm support are priorities. For procurement, buyers should note that fixed arms simplify the design but cannot be tailored to individual shoulder width or desk height. Planning should allow for assembly, with a reference time of 40 minutes per set. The product is supplied as one set in two cartons, with a reference packaged gross weight of 23 kg per set and reference carton volume of 0.26 m3 per set. Delivery and storage planning should use the stated packaging details rather than the chair’s assembled footprint alone.
