Product Description

The High-Back Ribbed Black Executive Swivel Chair combines a formal executive profile with structured comfort and mobility. Its black upholstered seat and tall segmented back use horizontal channel stitching and padded ribs, while the upper lumbar area remains smooth for a clean transition beneath the high-back frame. A polished tubular perimeter frame with slim side contours supports the visual outline, joined by one-piece polished aluminum loop armrests that run continuously from back to seat. Integrated black arm pads follow the curved tubing, and the polished five-star base completes the tailored black-and-metal appearance. Overall dimensions are 610 by 680 by 1170 mm, with 540 mm of clear width between armrests. Construction centers on a rigid load-bearing seat board with molded cut foam, paired with a framed back board using segmented foam or padded rib inserts. The finished seat cushion is 90 mm thick and uses 45 kg/m³ foam; the backrest padding is 70 mm thick with 35 kg/m³ foam. Foam rebound is rated at 40 percent. The black smooth-faced upholstery is 1.2 mm thick and rated for 50,000 Martindale abrasion cycles. Polished aluminum or chrome-finished framing, a black steel tilt mechanism, and a chrome-plated steel gas lift with a 50 mm outer tube provide the structural system. The chair weighs 18 kg net and carries a recommended user weight capacity of 150 kg. Functional features support active office use. The seat rotates 360 degrees around the central gas-lift axis, and pneumatic lever adjustment provides 80 mm of lift travel to a maximum seat height of 530 mm. The synchronized or center-tilt mechanism allows a 15-degree maximum recline with tension control, and an under-seat lever locks the chair in an upright position. The high ribbed back creates a 240 mm lumbar support zone and distributes contact across the lumbar and thoracic regions, while fixed loop arms place elbow support 240 mm above the compressed seat. Five 60 mm nylon or polyurethane twin-wheel casters allow rolling and swiveling on level office floors. The chair is suited to management offices, boardrooms, meeting rooms, private workstations, reception manager offices, and consultation settings. It fits desks with at least 700 mm of knee clearance and works over carpeted or hard-floor work areas. Its formal appearance is appropriate behind an executive desk or in spaces used for meetings lasting two to four hours. Procurement teams can specify the unbranded model EO-HB-RIB-ALU-01 for batch purchases where a 36-month warranty and 150 kg capacity are acceptance targets. Each set is supplied in two cartons, with packaged gross weight of 23 kg and carton volume of 0.26 m³. Reference assembly time is 40 minutes per set, and 135 sets fit a 20GP container at 85 percent space utilization.
