The Black Mesh Back Cantilever Office Guest Chair, model CANT-MESH-GUEST-01, is an unbranded stationary seating solution built for consistent professional use across formal and semi-formal work and meeting settings. Its sleek, streamlined visual profile features a taut black mesh back set within a matching black polypropylene structural frame, paired with a padded black fabric seat, fixed T-shaped polypropylene armrests, and a polished chrome-plated steel cantilever sled base that creates a clean, uncluttered silhouette suited to modern office aesthetics. Overall dimensions measure 610 x 590 x 1000 mm, with balanced proportions including a 500 mm wide, 450 mm deep seat set 450 mm from the floor, topped with a 70 mm thick cushion, a 570 mm tall, 470 mm wide backrest, and armrests positioned 180 mm above the seat surface for relaxed arm support during extended seated periods. Construction prioritizes durability and long-term comfort. The backrest uses taut breathable polyester mesh shaped with an integrated lumbar contour, tested to withstand 30000 abrasion cycles for sustained use. The seat core is built from 40 kg/m³ high-density polyurethane foam with a 45% rebound rate, upholstered in woven black polyester fabric, and supported by a 14 mm thick bent plywood internal board. The cantilever frame is formed from 32 mm diameter, 1.8 mm wall thickness chrome-plated steel tubing, with a 500 kg static frame load capacity, and finished with non-slip, non-marking polypropylene anti-tilt glides tested to 100000 durability cycles that protect hard flooring and reduce forward tipping risk. The chair supports a maximum recommended static user load of 120 kg, with a net weight of 9 kg. Functional design is tailored to low-distraction fixed seating: there are no casters, swivel mechanisms, seat height adjustment, armrest positioning controls, or active recline functions, with a fixed 100-degree back angle to encourage upright, focused posture. The chair is non-stacking, built for permanent setup, and ships knock-down for assembly, with an 40 minute assembly time per unit, packaged across two cartons. It is well suited for boardrooms and conference spaces, office reception and waiting areas, open workspace desk-side visitor seating, training and seminar rooms, and residential home office guest zones, pairing appropriately with 2.4 m executive desks. Procurement teams should note the 0.26 m³ packaged volume per set, 23 kg packaged gross weight, and 135 set load capacity for a 20GP container at 85% space utilization when planning bulk orders. No rolling or adjustment features mean this chair is not intended for active workstation use, making it ideal for static guest and attendee seating applications.
