Product Description

The Mid-Back Mesh Swivel Task Chair with Fixed Arms, model MBM-TASK-FA-650, is an unbranded office task chair designed for individual computer work and general workstation use. Its appearance is functional and understated, with a black flexible mesh back set within a contoured polymer outer frame. The frame incorporates a shaped lower-back region, and the mesh provides an open visual surface suited to everyday office settings. The seat is upholstered in fabric and paired with black molded T-shaped fixed arms that include padded contact pads. A black painted steel frame, gas cylinder, and tilt mechanism complement the black nylon five-star base and twin-wheel casters, giving the chair a coordinated mobile-office profile. The clear width between armrests is 540 mm, while the finished seat cushion thickness is 90 mm and the backrest padding thickness is 70 mm. The lumbar support zone measures 240 mm in height. Construction balances breathable support, cushioned seating, and structured components. The backrest uses flexible mesh stretched over an ergonomic plastic outer back, with a mesh tensile rating of 180 N warp and 140 N weft. The cushion uses fabric-upholstered high-resilience foam on a molded plywood or composite seat pan. Seat foam thickness is 70 mm, foam density is 35 kg per cubic meter, and the upholstery is rated for 50,000 Martindale abrasion cycles. The recommended user weight capacity is 136 kg, chair net weight is 13.5 kg, and seat static load verification is 102 kg. Pneumatic seat-height adjustment provides 100 mm of travel through a side actuating lever. The chair rotates 360 degrees around the central gas-lift axis and offers synchronous-style seat-and-back tilt with 12 degrees of rearward travel. A side tension knob controls tilt resistance, and the under-seat lever assembly provides a single-position upright lockout. Fixed arms offer consistent upper-body support, while casters and a five-star base support movement across typical workstation layouts. This model is appropriate for open-plan desks, home offices, and administrative workstations where breathable back support and compact mobility are needed. It is intended for single-user computer tasks at standard desk heights of 720 to 760 mm. Procurement planning should note that each set is supplied in two cartons, with packaged gross weight of 23 kg and carton volume of 0.26 cubic meter. Reference assembly time is 40 minutes per set. The reference carton dimensions are 850 by 420 by 720 mm, and the indicative 20GP loading is 135 sets at 85 percent space utilization.
