The High-Back Leather Executive Swivel Chair, model EXEC-HB-LTH-01, is an unbranded executive seating solution with a formal, high-backed profile. Its dark gray leather or leather-match upholstery is defined by visible edge stitching, padded side panels, and a continuous tall back that supports the shoulders and upper back. Integrated lateral upholstery gives the chair a structured, tailored appearance, while the polished die-cast aluminum five-star base provides a refined visual contrast with the black twin-wheel casters and black powder-coated steel tilt mechanism. The chair is built around a central chrome-plated steel pneumatic gas lift with an 80 mm visible stroke. The seat uses a 90 mm molded polyurethane foam cushion with a rounded waterfall front, set over a bent plywood or steel support deck. The back combines 70 mm contoured polyurethane foam with a tall internal support panel carried on molded plywood or a steel-reinforced composite panel. Padded leather-wrapped side panels extend the support around the user, and the clear width between armrests is 540 mm. Overall dimensions are 660 x 700 x 1260 mm, with a 240 mm lumbar support zone. Functionality is designed for executive and private office use. The seat rotates 360 degrees around the central column and adjusts pneumatically through an 80 mm lift stroke. A synchro-tilt mechanism allows the back to recline to an 18-degree rearward angle, while a side rotary knob adjusts tilt resistance for users up to 150 kg. An under-seat lever locks the chair upright or in selected recline positions. Five twin-wheel casters support omnidirectional movement on hard floors or low-pile carpet. This one-person chair is suitable behind a management desk, at a private workstation for computer and document work, in supervisor or meeting rooms, and in hotel-style business centers or business lounges where mobile seating and a polished finish are required. For coordinated planning, it can be paired with an executive desk and a work-surface height of 760 mm; the listed matching desk size is a 2.4 m executive desk. Procurement teams should note the chair is supplied as one set in two cartons, with reference assembly time of 40 minutes per set. Packaged gross weight is 23 kg per set, and the reference carton volume is 0.26 cubic meters. The chair presents a polished aluminum base, dark upholstery, and mechanical adjustability suited to professional interiors seeking a traditional executive look without specifying a branded manufacturer.
