The High-Back Leather Executive Swivel Chair, model EXEC-HB-PU-01, presents a formal executive office seating solution with a tall contoured backrest, padded fixed armrests, and a tailored dark gray leather-look upholstered finish. Piped edge seams give the seat and back a structured visual outline, while the polished aluminum five-star base and chrome gas lift create a refined contrast suited to professional interiors. Its 680 by 700 by 1180 mm silhouette offers single-person seating with a 540 mm clear width between armrests, balancing presence at a desk with a conventional executive layout. Construction combines upholstered comfort with durable internal support. The seat uses a molded polyurethane foam cushion core, 100 mm thick at a 45 kg per cubic meter density target, beneath a finished cushion thickness of 90 mm. The back cushion uses shaped polyurethane foam with a 70 mm thick lumbar section and 40 kg per cubic meter density target, supporting a 240 mm lumbar zone. A 12 mm molded plywood or equivalent load-bearing panel supports the seat, while the back uses a steel or bent plywood inner frame with an 18 mm structural profile. The armrests feature upholstered padded caps over rigid supports fixed to the seat shell. Functional details support daily executive use. The seat rotates 360 degrees around the chrome-plated steel gas cylinder, and pneumatic height adjustment provides 80 mm of travel, taking seat height from 440 to 520 mm. The synchro-style recline offers a 15-degree maximum tilt, controlled by a rotary tension knob and a multi-position lock for upright or reclined working positions. The black powder-coated steel tilt plate is rated for users up to 150 kg, matching the recommended user weight capacity. Five polished cast aluminum or aluminum-alloy base legs carry 60 mm black twin-wheel casters for movement on carpet or hard floors. The caster rolling target is 100,000 cycles and seat height adjustment is rated for 60,000 cycles. This chair is appropriate for managers and directors using 720 to 760 mm desks, private workstations focused on long-duration computer and document tasks, meeting rooms, reception meetings, financial advisory rooms, and managerial consultation spaces. It can also be procured in matching configurations with executive desks, visitor chairs, and conference furniture. Each set is supplied unbranded in two cartons with a packaged gross weight of 23 kg, 0.26 cubic meter carton volume, and a reference assembly time of 40 minutes. A 20-foot general purpose container can hold 135 sets at 85 percent space utilization, useful for project planning and coordinated office fit-outs.
