Product Description

The Mid-Back Mesh Swivel Task Chair with Fixed Arms, model OC-MB-FA-620, is an unbranded office chair designed for practical daily seating at individual workstations. Its overall form combines a black mesh back, dark gray upholstered seat, fixed black arms, and a five-star caster base, giving it a functional appearance suited to neutral office interiors. The backrest uses flexible black mesh stretched over a black molded polymer frame and includes a contoured central lumbar band. The seat is covered in dark gray woven textile with stitched edge piping and sits over a contoured molded polyurethane foam cushion on a load-bearing shell. Fixed T-shaped polymer arms with rectangular soft-touch pads provide consistent forearm support, while the clear width between armrests supports comfortable positioning at a desk. Construction balances lightweight mobility with structural support. The seat uses a molded polymer seat pan mounted to a steel mechanism plate, and the center structure features a black powder-coated steel telescopic gas lift with a polymer center shroud. The chair rests on a nylon five-star base fitted with nylon twin-wheel casters. Its listed specifications include a 90 mm finished seat cushion, 70 mm backrest padding dimension, 240 mm lumbar support zone height, 40 kg/m3 seat foam density, and a recommended user weight capacity of 120 kg. Material and durability targets noted for the product include a back mesh breaking-load target of 250 N per 50 mm strip, fabric abrasion acceptance at 50,000 Martindale cycles, static-load verification at 102 kg for one hour, and caster rolling durability of 100,000 cycles. For function, the chair provides pneumatic seat-height adjustment from 440 to 540 mm through a right-side lever with a 100 mm lift stroke. The backrest tilts from 93 to 110 degrees and can be locked or released using the side lever. A rear under-seat knob controls tilt tension, allowing the resistance to be adjusted to body weight and preferred reclining force. A 360-degree swivel seat and five twin-wheel casters allow users to turn and move within a workstation without lifting the chair. This model is appropriate for open-plan desks, private offices, and home offices where rolling swivel access and a breathable mesh back are priorities. It is intended for single-shift users up to 120 kg who prefer fixed arm support. Procurement planning should account for delivery as one set in two cartons, a packaged gross weight of 23 kg per set, 0.26 cubic meters of carton volume, and a reference assembly time of 40 minutes per set. The 20-foot container loading indication is 135 sets at 85 percent space utilization, useful for bulk purchasing and storage s.
