Product Description

The Gray Upholstered Mid-Back Swivel Executive Office Chair combines a structured professional silhouette with polished metallic detailing, making it well suited to settings that call for formal desk seating without a heavy visual profile. Its gray smooth upholstery is finished with stitched paneling, while the mid-height padded backrest, cushioned seat, and fixed arms create a neat executive appearance. The clear width between armrests is 540 mm, and the overall form is organized around a central chrome-plated gas column and five-star base. Five black nylon twin-wheel casters complete the chair's mobile, office-oriented layout. Overall dimensions are 630 by 650 by 1120 mm. The seat uses molded polyurethane foam 90 mm thick with a 45 kg/m3 target density and high-resilience characteristics. Backrest padding is specified at 70 mm in the dimension data and 80 mm in the material specification, supported internally by a 1.5 mm steel or shaped plywood panel. The seat support is a 12 mm bent plywood or steel-reinforced molded shell. Armrests feature polished chrome-plated steel tube or die-cast aluminum supports with gray top pads, while the base is a polished chrome-plated steel or aluminum five-star design with a 700 mm diameter and a 2.0 mm target metal section thickness. The chrome-plated steel telescopic gas column has a 50 mm outer diameter and a class 4 target grade. Functionally, the chair provides full 360-degree swivel movement and lever-operated pneumatic height adjustment with a 100 mm stroke and a 480 mm maximum seat height. Its synchronized or center-tilt mechanism allows a 15-degree maximum recline, with a rotary knob or paddle to regulate tilt resistance for users up to 150 kg. A single-position lock secures the backrest at the upright working angle through the side lever. The fixed arms offer a 230 mm elbow support height but do not adjust in height or pivot. The twin-wheel casters are intended for rolling on hard floors and low-pile carpet. This model fits private management offices, assigned open-plan workstations, and conference settings, including tables up to 760 mm high. It is also appropriate for home offices, studies, reception rooms, and formal advisory spaces where gray upholstery can complement neutral interiors. The recommended user weight capacity is 150 kg, net weight is 17 kg, and packaged gross weight is referenced at 23 kg per set. Delivery is configured as one set across two cartons, with a reference assembly time of 40 minutes per set and a reference carton volume of 0.26 cubic meters. Procurement teams should confirm replacement casters, the full assembly hardware count, and the upholstery code before order release, and should review the supplied carton dimensions for site receiving and storage planning.
