The Cognac Upholstered Height-Adjustable 4-Star Swivel Lounge Office Armchair, model SWL-4S-CGN-ADJ, embodies a modern minimalist aesthetic with clean lines and a cohesive low-profile silhouette. It features continuous wrap-around padded armrests that flow seamlessly from the seat to the backrest, creating an integrated, enveloping form without disjointed components. Its caster-free fixed 4-star base sits flush to the floor, eliminating protruding elements for a polished, uncluttered layout that suits refined interior schemes. Built for lasting daily use, the chair is constructed around a 1.5mm thick welded steel internal support frame, with a plywood core for the seat and back shell wrapped in high-density polyurethane foam—80mm thick in the seat at 25 kg/m³ density, and 60mm thick in the back. Upholstery is 1.2mm matte cognac brown PU faux leather rated for 50000 Martindale abrasion cycles, balancing soft texture with wear resistance. The 2mm thick brushed polished die-cast aluminum 4-star base connects to a chrome-plated Class 3 pneumatic lift, operated via a black powder-coated steel adjustment lever, with a sealed central bearing enabling smooth rotation. The entire unit has a net weight of 28 kg and supports a maximum static load of 204 kg. Functional design prioritizes flexible, stable use: the gas lift delivers 100mm of travel to adjust seat height between 440mm and 540mm, 360-degree swivel allows easy reorientation without shifting the base, and the caster-free design prevents unintended movement for secure stationary placement. The wrap-around armrests sit 180mm above the seat to support forearms during extended seated sessions, while plush foam padding delivers consistent comfort for both short visits and longer casual stays. Overall dimensions measure 760 x 660 x 880 mm, with a 660mm wide seat, 560mm deep seat, and 680mm wide, 320mm high backrest. This chair is ideal for two core commercial settings: positioned in front of executive desks as guest seating for short-stay office visitors, or placed in open collaboration lounge areas and breakout zones to support informal meetings, focused individual relaxation, and casual team check-ins. Its warm cognac finish pairs well with neutral wood, metal, and fabric office palettes. For procurement, note that each unit ships as one set across two cartons, with packaged gross weight of 23 kg per set and total carton volume of 0.26 m³. On-site assembly requires 40 minutes per set, and 20-foot GP containers can hold 135 sets at 85% space utilization for large-scale project planning.
