The Brown Mid-Back Height-Adjustable Swivel Executive Office Chair, model EXE-MB-BR-700C, delivers a polished, professional seating solution balancing structured comfort and functional versatility for a wide range of workspaces. Visually, it features a cohesive warm brown upholstered seat, backrest, and integrated wrap-around armrests paired with a sleek polished chrome 5-star base, creating a refined silhouette that complements both formal and casual work environments without overpowering surrounding decor. Its mid-back profile and compact base footprint align neatly with standard desk setups, supporting flexible layout arrangements in both commercial and residential settings. Constructed for long-term regular use, the chair is built around a 12mm thick bent plywood internal frame, upholstered in 1.2mm brown PU faux leather over high-density contoured foam padding. The seat uses 35 kg/m³ density foam at 80mm thickness, while the backrest incorporates 30 kg/m³ density foam at 60mm thickness, with a built-in lumbar curve to support the lower back during extended seated tasks. The 2mm thick polished chrome-plated steel 5-star base supports a chrome-plated steel gas lift cylinder, paired with a 2.5mm thick steel plate center-tilt mechanism, and floor-protective black dual-wheel PU casters. Integrated fixed armrests are upholstered to match the seat and back, delivering consistent forearm support during work. Core functional features include 80mm stroke pneumatic seat height adjustment operated via a side lever, full 360-degree swivel, a center-tilt system with tension control and infinite position lock, and smooth mobility across carpet, tile, and wood flooring. The adjustable seat height reaches 540mm, aligning with standard 760 mm height desks to support ergonomic positioning. This chair fits equally well in private executive offices, where its warm brown aesthetic complements premium manager workspace decor; open-plan workstations, where its slim base fits standard cubicle layouts; conference rooms, where swivel and mobility support easy repositioning around meeting tables; home offices, where its mid-back scale suits residential spaces without overwhelming room proportions; and reception areas, where its polished chrome base creates a professional first impression for visitors. It supports a maximum user weight of 181kg, with a gas lift tested to 120000 operational cycles. For procurement planning, note each unit ships in 2 cartons, with a reference assembly time of 40 minutes per set.
