The High-Back Two-Tone Leather Executive Office Chair, model EXEC-HB-TT-700 from an unbranded line, presents a formal executive profile with a light warm-white leather or leather-look seat and padded backrest. Horizontal stitch channels structure the back face, while dark gray upholstered or coated rigid side frames wrap the back and arms. Light-colored padded arm pads are bonded to the dark outer arm shells, producing a disciplined two-tone appearance suited to professional interiors. Its polished aluminum five-star base, chrome gas-lift column, and twin-wheel casters complete the visual layout. Overall dimensions are 700 by 700 by 1220 mm, with 540 mm of clear width between the fixed arms. Construction combines a 12 mm molded plywood or engineered composite internal back shell with a 12 mm molded plywood or high-density composite seat carrier. The seat uses 90 mm high-resilience polyurethane foam at 45 kg per cubic meter, and the back includes a 30 mm polyurethane comfort layer at 35 kg per cubic meter beneath a stated 70 mm backrest padding profile. The 240 mm lumbar support zone reinforces the high-back form. A steel mechanism supports the synchronized seating functions, and the upholstery carries a 50,000 Martindale abrasion target. Pneumatic seat-height adjustment operates through a lever, with seat height from 450 mm to 530 mm. The chair rotates 360 degrees around the chrome center column and provides synchronized seat-and-back recline with 15-degree maximum backward travel. A rear rotary knob controls tilt tension according to user body weight, while a side lever offers upright lock, intermediate lock, or free-tilt mode. The integrated fixed arms provide 230 mm of padded forearm support without width or height adjustment. Five twin-wheel casters are intended for hard floors and low-pile carpet. Published capacity is 150 kg, with static seat verification at 680 kg, backrest durability at 120,000 cycles, gas-lift stroke of 80 mm, and caster rolling durability of 100,000 cycles. The chair fits private manager offices, boardrooms, conference tables, reception counters, administrative workstations, and premium home offices. It is also appropriate for legal, financial, and consulting environments where leather-look upholstery and chrome detailing are desired. Procurement planning should account for one set packed in two cartons, 23 kg packaged gross weight, 0.26 cubic meter package volume, 40-minute assembly time, and 135 sets per 20GP container at 85 percent space utilization.
