Product Description

The Ribbed High-Back Swivel Executive Office Chair presents a formal modern silhouette through its tall black ribbed back, padded seat, and polished chrome tubular armrest frame. Horizontal stitched channels give the upholstery a structured executive appearance, while the contoured back panel and high-back shape provide support from the lumbar region toward the lower shoulders. The cantilevered arm frames visually lighten the design and carry padded black arm pads that complement the five-star chrome base and black twin-wheel casters. Its overall dimensions are 590 by 620 by 1010 mm, with a 540 mm clear width between armrests. The seat is upholstered in black smooth material with horizontal stitching and includes a 90 mm finished cushion over an 80 mm high-resilience polyurethane foam core with a 45 kg/m3 density target. The back uses 70 mm padding over a 50 mm molded polyurethane cushion with a 35 kg/m3 density target. Internal construction includes a molded plywood or reinforced composite seat carrier, a steel or reinforced polymer back frame, a black steel multi-position tilt mechanism, and a 50 mm Class 4 chrome-plated steel gas-lift cylinder. The chair weighs 18 kg, accommodates one user, is recommended for users up to 150 kg and 190 cm tall, and uses a five-star base with a 1136 kg static-load reference. Its casters have a 100,000-cycle rolling durability reference. Functionality centers on adaptable desk support. A visible side lever controls 100 mm of pneumatic height adjustment to a 540 mm seat height. The back offers 118 degrees of tilt travel with multi-position locking, while a rotary tension knob adjusts resistance to user weight and recline force. The fixed armrests provide 230 mm of forearm support without width or height adjustment, and five 60 mm twin-wheel casters enable omnidirectional movement on hard floors or carpet. The ribbed back channels are designed to flex and distribute contact across separate padded panels. This model suits manager offices, open-plan workstations, conference rooms, reception or consulting spaces, and dedicated home offices with standard 760 mm desks. For procurement, confirm the exact upholstery grade through the supplier bill of materials and select optional soft casters for wood, tile, or carpet. Each set ships in two cartons, with a packaged gross weight of 23 kg, a reference volume of 0.26 cubic meters, and an indicative assembly time of 40 minutes. A 20GP container can hold 135 sets at 85 percent space utilization. The unbranded EOA-HB-RIB-01 is best specified where a consistent black-and-chrome executive look is needed across multiple work or meeting settings.
