Product Description

The Tan Upholstered Swivel Executive Armchair is a mid-back office chair with a refined, residential-friendly appearance. Its tan seat and back create a warm visual profile, while the integrated upholstered arms curve continuously from the back shell for a structured, streamlined look. The chair pairs soft tan upholstery with a polished aluminum-alloy five-star base and black twin-wheel casters, balancing executive styling with practical mobility. Its overall dimensions are 620 by 640 by 1010 millimeters, with a 540-millimeter clear width between the armrests and a compact footprint suited to individual workstations. Construction centers on a molded inner shell supported by a welded steel plate. The seat uses molded polyurethane foam with an 80-millimeter cushion and a fabric or polyurethane outer surface, while the back features 60 millimeters of contoured polyurethane foam over a rigid inner shell. The finished seat cushion thickness is 90 millimeters, backrest padding is 70 millimeters, and the lumbar support zone is 240 millimeters high. The seat-front foam density is 35 kilograms per cubic meter, with back foam density of 28 kilograms per cubic meter and 35 percent foam resilience. The polished five-star base uses radial spokes and is fitted with five black nylon twin-wheel swivel casters with hard treads. Height is controlled through a chrome-plated steel telescopic gas column with a 50-millimeter outer diameter and 100 millimeters of travel, allowing seat height adjustment from 450 to 550 millimeters using a side lever. A black steel multi-position tilt mechanism provides synchronized seat-and-back movement with a 12-degree recline, a three-position lock covering upright, mid-recline, and full-recline settings, and a manual tension knob for users up to 130 kilograms. The chair also offers continuous 360-degree rotation, and each caster enables omnidirectional rolling and swivel movement. This model is suitable for private executive offices, open-plan workstations, meeting rooms, home offices, reception or interview settings, and project rooms. Its tan finish and integrated arms make it appropriate where a less technical, high-back aesthetic is preferred, while its mobility and adjustable height support shared desks and changing users. Procurement teams should note the unbranded model OFC-MID-TAN-5STAR is supplied as one set in two cartons, with packaged gross weight of 23 kilograms and reference assembly time of 40 minutes per set. The carton dimensions are 850 by 420 by 720 millimeters, with a reference volume of 0.26 cubic meter per set, useful for delivery, storage, and installation planning.
