Product Description

The High-Back Tan Leather Executive Swivel Chair, model OFC-HB-TAN-01, presents a polished executive seating solution defined by its warm tan upholstery, tall continuous backrest, and contrasting black angular arm frames. Its five-star chrome base adds a refined metallic accent, while horizontal seam detailing on the back and smooth leather-look surfaces give the chair a structured, modern office character. From a layout perspective, the high-back profile creates a formal focal point behind a desk, and the swivel base supports easy positioning without disrupting the chair’s upright silhouette. Construction combines padded comfort with a steel support structure. The seat uses tan smooth leather-look upholstery over molded polyurethane cushioning, with a finished cushion thickness of 90 mm and a procurement density of 45 kg/m3. The backrest features a continuous upholstered tan panel with 70 mm polyurethane padding and a 35 kg/m3 procurement density, including a defined lumbar support zone. The armrests use black painted steel loop frames with a 25 by 25 mm section and tan upholstered pads over foam. Mobility is provided by a chrome-plated steel base and gas lift, polyurethane dual-wheel casters, and a polished metal base with a 660 mm footprint. The upholstery material is 1.2 mm thick, with a 50,000 Martindale abrasion resistance target. Functionally, the chair offers 360-degree swivel movement around the central gas-lift axis and a 100 mm height-adjustment stroke operated by a left-side lever. The synchro-style tilt plate allows a 15-degree recline and includes one upright lock position, while a manual tension knob beneath the seat enables adjustment for user weight up to 150 kg. Fixed angled arm supports provide elbow support 220 mm above the seat, and the 720 mm padded back supports the thoracic and lower shoulder region. Its casters are intended for movement on hard floors or carpet. The chair is well suited to manager or director offices, private workstations, boardrooms, consultation rooms, and hotel business centers. Its consistent tan finish and chrome base also make it appropriate for multi-unit commercial interiors where a uniform appearance is required. Procurement teams should note the unbranded supply format, two-carton packaging, 23 kg packaged weight, 40-minute reference assembly time, and suitability for bulk container planning. Durability targets cover the gas lift, casters, seat-front impact, backrest loading, static vertical load, and base static load, supporting specification for regular professional use.
