Product Overview & Construction Details

The GUOYOU EX-HB-LTHR-001 is a high-back padded leather executive office chr featuring polished aluminum arms and base, designed with a sleek, modern angular silhouette that balances professional aesthetics and ergonomic function. Its visual form centers on a sculpted high backrest with integrated lumbar contouring, framed by polished die-cast aluminum armrests and a matching tapered five-star base that delivers a refined, contemporary look suited to premium workspace settings. Constructed with a visible black top-grn leather upholstery face on the seat and front backrest, pred with matching PVC on sides and rear, the chr features fine, consistent 6 mm stitch spacing across its padded surfaces. The seat cushion uses high-density polyurethane foam for firm edge support, while the backrest incorporates layered foam with a built-in lumbar pad for targeted lower-back shaping. Its internal structure relies on a plywood or bent wood back frame with steel reinforcement brackets, a 14 mm bent plywood seat support board, and a steel tilt mechanism with black powder-coated housing. The polished die-cast aluminum five-star base provides a stable foundation, pred with a chrome-plated Class 3 commercial-grade gas lift cylinder and black polyurethane casters with steel axles. For practical use, the chr offers pneumatic seat height adjustment via a right-side lever, with 100 mm of gas lift travel to accommodate varying desk heights. Its tilt mechanism supports up to 18 degrees of recline from the upright position, with multi-position locking and a rotary tension knob to adjust recline resistance to user body weight. Additional functions include full 360-degree swivel for easy desk access, smooth multidirectional mobility from five dual-wheel casters, and fixed padded armrests positioned for forearm support. The fixed ergonomic armrests and integrated lumbar contour deliver consistent, low-mntenance support for dly work. This chr is suited for a range of commercial and select residential spaces. It fits naturally in executive and C-suite private offices, where its premium leather finish and high-back support meet the demands of extended dly use. It works well as head-of-table seating in conference and boardrooms with modern or contemporary interiors, and aligns with standard managerial workstation desks. In reception and visitor areas, it serves as upscale guest seating that coordinates with executive furniture collections, and it meets the durability requirements of Class A commercial office buildings and premium co-working suites with hard floors or low-pile carpet. Procurement teams should note that key material specifications including exact leather grade, foam density, mechanism type, and gas lift load rating require confirmation via supplier documentation or bill of materials. The chr ships in knock-down form with one unit per carton, requiring assembly with basic tools. Freight planning can reference the net weight and carton volume s, while load capacity and wear resistance figures serve as procurement benchmarks for evaluating long-term commercial suitability.
