The Black Leather Upholstered Executive Office Chair, model EXEC-LEA-001, presents a refined, professional silhouette tailored to formal work environments. Its high-back structured form features fixed padded armrests positioned to create open seat access, anchored by a broad five-star base that balances visual weight with functional stability. The black bonded leather upholstery is accented by matched stitching at panel seams, pairing with polished wood finishes on the armrest frames and base to deliver a cohesive, upscale executive aesthetic. Constructed for long-term regular use, the chair’s seat and backrest are built with high-density, flame-retardant polyurethane foam cores wrapped in soft polyester fiber, supporting users with a 90mm thick seat cushion and 70mm thick backrest that includes a dedicated 240mm tall lumbar support zone. The curved solid wood armrests are topped with matching leather padding for resting comfort, while the five-star polished wood base connects via a steel central hub fitted with polyurethane dual casters suitable for both carpet and hard flooring. Height adjustment is powered by a chrome-plated steel gas lift, paired with a 2.5mm thick steel plate multi-lock tilt chassis for reliable structural performance. Core functional features support flexible, comfortable work positioning: a side lever operates 80mm of seat height adjustment to align with standard 760mm desk heights, the backrest reclines to an 18-degree angle with multi-position locking and customizable tilt tension, full 360-degree swivel allows easy access to surrounding work areas without repositioning the base, and smooth-rolling casters enable simple adjustment of seat placement. The chair supports a maximum user weight of 160kg. This model is well suited for private executive offices as primary seating for senior management during full workdays, and for formal conference rooms as premium seating for leadership or invited guests. For procurement planning, note that each unit ships in two cartons, requires 40 minutes of assembly per set, and can be loaded in quantities aligned with standard 20GP container capacity calculations for large-scale furnishing projects.
