Product Description

The Mid-Back Tan Leather Executive Swivel Chair, model OFC-MB-TAN-AL5, presents a formal executive profile with warm tan upholstery, a mid-height back, fixed padded arms, and a bright polished metal five-star base. Its angular arm supports and tailored cushioning give the chair a structured business appearance, while the contoured back and rounded arm-pad fronts soften the visual line. Overall dimensions are 650 by 680 by 1030 mm, with 540 mm between the armrests, making it suitable for a substantial executive desk without appearing oversized. The unbranded design supports coordinated installations where a consistent tan and polished-metal finish is preferred. Construction combines upholstered comfort with durable load-bearing components. The seat uses tan full-grain or corrected leather on the face with leather-match sides, fitted over a 90 mm polyurethane foam cushion at a 45 kg per cubic meter density target and a shaped support board. The back uses tan leather or leather-match over a contoured 70 mm foam panel and rigid carrier. Internal framing is 15 mm molded plywood or steel-reinforced composite with steel mounting plates; the back frame is 18 mm molded plywood or a 1.5 mm steel bracket. Arm supports are polished die-cast aluminum or stainless steel, the gas lift is chrome-plated steel with a 50 mm outer tube, and the mechanism plate is steel. Twin-wheel nylon casters complete the base. The chair weighs 18 kg and carries a recommended user weight capacity of 160 kg, matched by the gas-lift static load rating. Maximum recommended occupant height is 190 cm. Functionality is centered on daily desk use. A central gas lift provides 360-degree swivel and 60 mm of pneumatic seat-height travel, reaching a 500 mm seat height. The steel under-seat mechanism offers synchronized or center tilt, reclining to 115 degrees with a locked upright position at 90 degrees. A rear rotary knob adjusts tilt tension for users up to 160 kg. Fixed armrests sit 230 mm above the seat for forearm support during keyboard work, and a 240 mm high contoured lumbar contact zone provides passive lower-back support. Five 60 mm twin-wheel casters allow movement on hard floors and low-pile carpet. The chair fits private executive offices, including placement behind a 2000 mm executive desk, as well as manager workstations in open-plan areas. It is also appropriate for meeting rooms, home offices paired with a standard 760 mm desk, and reception or consulting spaces that require a refined leather-like appearance. For conference use, the passive lumbar support and fixed arms suit meetings lasting several hours. Procurement teams should note that each set ships in two cartons, with packaged gross weight of 23 kg, carton dimensions of 850 by 420 by 720 mm, and reference assembly time of 40 minutes. Carton volume is 0.26 cubic meters per set, and an indicative 20GP container loads 135 sets at 85 percent space utilization. Batch ordering with matching tan guest chairs is recommended for private offices and director suites.
