Product Description

The High-Back Tan Leather Swivel Executive Chair, model EXEC-HB-TAN-5S, presents a traditional executive form with a tall padded back, generously proportioned seat, and integrated curved arms upholstered in a neutral tan leather-facing material. Its visible stitching, padded armrests, polished five-star base, and high-back silhouette create a formal appearance suited to professional interiors while maintaining a practical office layout around a desk or meeting table. Overall dimensions are 650 by 700 by 1240 millimeters, with 540 millimeters of clear width between the armrests. The 240-millimeter lumbar support zone and fixed arms offering 230 millimeters of upper forearm support reinforce the chair’s structured, single-user design. Construction combines cushioned comfort with a rigid load-bearing frame. The seat uses tan leather-faced upholstery over 90 millimeters of 45 kg/m3 high-resilience polyurethane foam, supported by a 12-millimeter molded plywood board with a steel reinforcing plate. The backrest features a 70-millimeter, 35 kg/m3 polyurethane foam pad attached to a 12-millimeter bent plywood or molded composite shell. Armrest pads match the tan upholstery and sit on curved structural supports. The black powder-coated steel synchro mechanism uses a 4-millimeter plate, paired with a 50-millimeter Class 4 black steel gas lift with chrome inner tube and a polished aluminum five-star base. Polyurethane twin-wheel casters complete the assembly. The chair weighs 23 kilograms and is intended for users up to 150 kilograms; stated verification targets include 300 kilograms for seat static load, 150 kilograms for backrest static load, 500 kilograms for base static load, and 100,000 caster rolling cycles. Functionally, the chair provides full 360-degree swivel and 100 millimeters of pneumatic seat-height travel through a side actuator. Its synchronized recline allows 15 degrees of back movement with a coordinated 6-degree seat tilt. A rotary knob offers five tension settings, while the four-position lock secures the back at upright, 5-degree, 10-degree, or 15-degree angles. The five twin-wheel casters support movement on hard floors and low-pile carpet. The model is appropriate for private executive offices, boardrooms, managerial workstations, and legal, financial, or consulting meeting spaces. It is best allocated to one assigned user rather than used for continuous hot-desking, and pairs with a 760-millimeter executive desk. For procurement, delivery is planned as one set in two cartons, with reference assembly time of 40 minutes. Carton dimensions are 850 by 420 by 720 millimeters, packaged gross weight is 23 kilograms per set, and carton volume is 0.26 cubic meters. An indicative 20-foot container load is 135 sets at 85 percent space utilization. Buyers should confirm that soft-tread casters are supplied for wood, tile, sealed concrete, or low-pile carpet installations. The product is unbranded.
