The Mid-Back Height-Adjustable Armrest Cantilever Office Visitor Chair (model CVC-ADJARM-665BLK) is an unbranded commercial-grade seating solution tailored for structured public and office environments. Its clean, linear silhouette features a tailored mid-back profile paired with a sleek polished chrome cantilever sled base, delivering a formal, streamlined aesthetic that coordinates with a wide range of professional interior schemes without distracting visual clutter. All upholstered surfaces are finished in smooth black 1.2mm thick PU leather, with consistent 8 stitches per inch seam construction for a polished, durable finish. The contoured waterfall front seat edge is shaped to reduce pressure on the backs of users’ legs, while the fixed 95-degree upright back angle supports formal, attentive posture aligned with professional meeting settings. The chair supports a recommended static load of 125kg, anchored by a rigid 2.0mm wall thickness polished chrome-plated steel tubing frame that is fixed, non-swivel and non-tilting for stable, secure placement. The seat is built on an 18mm double-layer bent plywood core, topped with 80mm thick 45kg/m³ density high-elastic polyurethane foam, while the backrest uses 60mm thick 35kg/m³ density high-elastic polyurethane foam for balanced, long-lasting support. Hard-wearing black polyurethane armrest pads, mounted on reinforced black engineering plastic supports, offer 70mm of vertical travel with a simple button-activated lock securing two preset height positions to accommodate varied user needs. Integrated anti-scuff polymer glides on the sled base floor contact points protect hard flooring surfaces from scuffs and scratches during repositioning. Note that this chair is not designed for vertical stacking, and the backrest does not support the referenced recline or position lock functions, remaining fixed in the upright posture configuration. This seating solution is suited for a wide range of public and professional spaces, including formal conference rooms for group collaboration around meeting tables, office lobby reception waiting areas where its non-rolling base enhances safety for high-traffic flow, guest seating positions adjacent to 2.4m executive desks in private offices, fixed row arrangements in training rooms to support upright engagement during sessions, and easy-clean durable seating for public sector government or service center waiting zones. For procurement planning, each chair is delivered in 2 cartons per set, with a packaged gross weight of 23kg and total carton volume of 0.26 m³. Assembly requires an 40 minutes per unit, and 135 sets can be loaded into a 20-foot general purpose container at 85% space utilization. The structural frame is covered by a 10-year warranty for long-term commercial use peace of mind.
