The Gray Upholstered High-Back Swivel Executive Chair, model EXEC-HB-GRY-CA01, presents a formal executive seating profile with a tall gray upholstered back, matching seat, and padded fixed armrests. Its back panel includes a sewn horizontal contour and an integrated padded lumbar zone, while the polished five-star base, black casters, and black under-seat tilt mechanism give the chair a structured commercial appearance. Overall dimensions are 690 by 720 by 1190 mm, with a 540 mm clear width between armrests. The design accommodates one person and suits settings where a traditional high-back office chair is preferred. Construction centers on foam-padded seating supported by a polished telescoping steel gas-lift column with a black center sleeve. The seat uses a 100 mm molded polyurethane cushion with a 45 kg per cubic meter procurement density target, while the tall back uses 70 mm polyurethane padding with a 35 kg per cubic meter target. Finished cushion thickness is 90 mm, and the lumbar support zone is 240 mm high. Gray woven or leather-grain upholstery covers the foam; the exact textile or leather type should be confirmed through the supplier bill of materials. Armrests combine upholstered pads with gray support shrouds over a steel or reinforced inner bracket, subject to BOM confirmation. The tilt plate is black powder-coated steel, and the twin-wheel casters are black nylon or polyurethane with metal mounting stems. Functionally, the chair provides pneumatic height adjustment through a side lever, with seat height moving from 450 to 540 mm across a 90 mm gas-lift stroke. It rotates 360 degrees and reclines 15 degrees through a conventional synchro or center-tilt mechanism. An upright tilt lock and adjustable tension support user preference, while the five casters enable movement on hard floors or low-pile carpet. Fixed padded arms provide 230 mm of elbow support without positional adjustment, and lumbar support is integrated rather than separately adjustable. The suggested user weight capacity is 159 kg, and the chair is intended for up to 8 hours of daily use. It is appropriate for private executive offices, manager workstations, conference rooms, home offices, reception or counseling spaces, and individual commercial workstations with standard 720 to 760 mm desk heights. Procurement teams should note the unbranded supply model, 20 kg net weight, 23 kg packaged weight, shipment as one set in two cartons, and 40-minute reference assembly time. Before bulk ordering, specify floor-protective soft casters for hard floors and approve an upholstery fabric or leather sample.
