Product Description

The High-Back Gray Executive Swivel Chair, model OF-HB-GRY-01, presents a professional commercial-office form with a gray padded seat and tall upholstered back. The back is divided into three padded zones, while the seat uses visible horizontal seam construction for a clean, structured appearance. Black molded polymer arm pads and black mechanism components contrast with the gray upholstery, and a polished aluminum five-star base gives the chair a refined executive profile. Twin-wheel casters complete the visual layout and support movement around the workplace. The fixed T-shaped arms provide a clear 540 mm width between armrests, with forearm support positioned 230 mm above the seat. Construction balances comfort and durability. The cushion core uses molded polyurethane foam, with a 90 mm finished seat cushion and 70 mm finished backrest padding; reference core thicknesses are 80 mm for the seat and 60 mm for the back. A 240 mm lumbar support zone is integrated into the high-back panel. Inside, the chair uses a 12 mm molded plywood or reinforced polymer seat board, together with a 20 mm steel-tube or reinforced polymer back frame. Arm supports use black painted or powder-coated steel or die-cast brackets, and the synchro-tilt mechanism is housed in black painted steel. A chrome-plated steel gas lift with a 50 mm outer diameter connects the seat to the polished aluminum base. Designed for practical daily use, the chair rotates 360 degrees around the central gas-lift axis. Pneumatic height adjustment operates through a side lever over an 80 mm stroke. The synchronized seat-and-back tilt allows a 15-degree maximum back recline, with multi-position lock control under the seat and a knob for adjusting recline resistance. The chair is recommended for users up to 150 kg. Service references include 100000 height cycles, 300000 recline cycles, 100000 caster rolling cycles, a 500 kg static base load, and upholstery abrasion rated to 50000 Martindale rubs. Overall dimensions are 680 x 700 x 1220 mm, and the chair weighs 21 kg. It suits executive offices, private computer workstations, meeting and boardroom settings, dedicated home studies, and reception management desks. Its high-back support is appropriate for managers, directors, reception staff, and home-office users seeking a commercial appearance. Procurement teams should specify carpet-safe or hard-floor casters after confirming the floor finish. Each set ships in two cartons with a packaged gross weight of 23 kg and reference carton volume of 0.26 m3. Assembly time is 40 minutes per set, and 135 sets fit a 20GP container at 85 percent space utilization.
