The KETAI EOB-MB-WA-5C-01 mid-back executive office chair delivers a polished, professional seating solution tailored to refined work environments. Its visual design balances soft, tailored upholstery with warm dark wood accents, creating a sophisticated silhouette that complements formal office aesthetics. The contoured mid-rise backrest pairs with generously proportioned seat cushioning, while curved armrests trimmed in dark mahogany-stained wood finish frame the seating area, anchored by a matching 5-star caster base that creates a cohesive, streamlined look without visible bulky hardware. Construction prioritizes durable, long-wearing materials built for consistent daily use. The seat and back are upholstered in black top-grain cowhide over CAL 117 compliant molded foam, with 8mm seam pitch and reinforced edge stitching to prevent fraying at high-wear points. Armrests feature solid dark wood-finish frames topped with padded upholstered surfaces for comfortable arm support, while the internal seat frame uses 1.8mm thick powder-coated steel for rigid core support. The 5-star base uses a 2.0mm thick steel core with a matching dark wood finish overlay, fitted with dual-wheel nylon hooded casters designed for use on both carpet and hard flooring surfaces. Core functional features support flexible, comfortable use across long work sessions. The chair enables 360-degree full rotation around its central gas lift post, with pneumatic Class 3 height adjustment that allows vertical travel to suit a range of desk heights. A center tilt mechanism includes adjustable tension control and an upright position lock to let users customize their preferred seating angle, while smooth-rolling casters allow easy repositioning across standard office floors without surface damage. The 140mm thick seat cushion uses high-density foam with balanced rebound to maintain supportive shape over extended use. This chair is well suited for private executive offices, dedicated management workstations, and fixed conference room seating for long-duration meetings, pairing well with traditional wood office furniture as well as modern dark-toned workstations. For procurement planning, note that each unit ships across two cartons, with an assembly time of 40 minutes per set, and shipments are sized for efficient container loading for commercial bulk orders. The recommended static weight capacity supports a wide range of users, and abrasion-resistant upholstery is engineered to hold up to frequent daily use across high-traffic professional spaces.
