The High-Back Gray Upholstered Executive Swivel Chair, model EXEC-HB-GRY-01, presents a structured executive-office appearance through a tall upholstered back, padded seat, fixed loop arms, and a coordinated gray five-star base. Its smooth gray leather-look upholstery creates a continuous visual surface on the back, while a separate curved lumbar cushion defines the lower-back zone. The closed polymer arms wrap from the back support toward the front seat rail, giving the chair a formal side profile and a consistent neutral finish suited to coordinated office interiors. Overall dimensions are 660 by 660 by 1180 mm, with 540 mm of clear width between the armrests. The seat is fitted with a 90 mm finished cushion using molded polyurethane foam, and the backrest includes 70 mm of finished padding. Under the upholstery, the seat foam density target is 45 kg/m3, while the back foam density target is 35 kg/m3. The face material is 1.0 mm thick, and the chrome-plated steel telescopic gas lift provides a polished central accent against the gray molded polymer arms and nylon or polypropylene five-star base. Black twin-wheel casters complete the mobile base. Functionally, the chair supports 360-degree swivel movement and pneumatic seat-height adjustment through a right-side lever, with seat height ranging from 440 to 540 mm. A center-tilt mechanism reclines the seat and back together to a 15-degree rearward angle. An under-seat lever provides a single-position upright lock or a free-tilt mode, while a rear under-seat knob adjusts recline resistance. The fixed armrests rise 230 mm above the seat, and the integrated lumbar cushion offers passive lower-back contact without adjustable depth. The recommended user weight capacity is 136 kg, and the gas lift carries a Class 4 procurement target. This model is well suited to manager and director offices, private workstations, formal meeting and consultation rooms, and hotel or club business centers. It pairs with executive desks at the 760 mm height endpoint and supports rolling mobility in both individual workspaces and areas where chairs may be repositioned. Procurement teams should select casters according to hard-floor or soft-floor conditions, confirm the gray polymer and upholstery finish against existing furniture, and plan for two-carton delivery. Reference assembly time is 40 minutes per set, packaged gross weight is 23 kg, and carton volume is 0.26 cubic meters per set, supporting straightforward bulk-space planning for commercial furnishing projects.
