Product Description

The Yiankang EXEC-TUF-MID-MAH-001 mid-back tufted leather executive office chair balances classic formal aesthetics with functional performance for professional and premium residential settings. Visually, the chair features a structured tufted backrest accented by polished chrome tufting buttons, framed by solid hardwood trim finished in a rich mahogany stain with clear satin lacquer. Fixed padded armrests mirror this wood trim detail, paired with a matching 5-star wood base for a cohesive, traditional executive silhouette. The chair’s fixed maximum seat height aligns with standard desk heights, with a mid-back profile designed to support the lumbar and lower thoracic region without blocking cross-table sightlines in shared meeting spaces. Construction uses layered, durable materials selected for long-term commercial use. Seat and backrest surfaces are upholstered in black top-grain leather, stitched to a commercial-grade seam density to resist separation. High-resilience polyurethane foam forms the seat cushion, while molded polyurethane foam lines the backrest to deliver integrated lumbar support aligned to the natural lower back curve. Internal structural support comes from multi-ply birch plywood framing, connected to a powder-coated steel central swivel column and tilt mechanism. The 5-star base uses solid hardwood legs reinforced with internal steel inserts at caster mounts, fitted with black nylon dual-wheel casters engineered for low-noise, scuff-free movement on hard flooring and low-pile carpet. Core functional features support extended daily use, including 360-degree swivel rotation, smooth height adjustment via a side-mounted lever, a 12-degree rearward tilt with single-position lock, and adjustable tilt tension to accommodate different user weights. The fixed padded armrests are positioned to support relaxed elbow placement during typing and desk work, while the wide 5-star base delivers consistent stability during normal recline and movement. This chair is well-suited for executive private offices, formal boardrooms, high-end reception waiting areas, and dedicated home executive offices, where its leather and wood finish conveys a polished, premium aesthetic. It is designed to align with standard 750mm height desks and executive desk formats. For procurement, stakeholders can select from two standard finish options, and should note the product ships in knock-down packaging for efficient container loading, with straightforward assembly required. The chair carries a standard 3-year commercial warranty covering structural components and upholstery, with a maximum recommended user weight aligned to commercial office furniture specifications. Buyers should confirm exact material grades and test data directly with suppliers during final specification validation.
