The 3-Seat Black PU Public Beam Waiting Chair with End-Armrest Charging Ports is a streamlined, high-durability public seating solution designed to balance functional utility and understated visual appeal for high-footfall spaces. Built in a fixed linear 3-seat gang configuration without intermediate armrests, the chair presents a sleek, unified silhouette finished in matte black upholstery, complemented by polished silver aluminum end armrests with a rounded open-loop design, wood-tone edge trim along seat and back perimeters, and silver matte die-cast aluminum support legs for a polished, modern aesthetic that aligns with a wide range of interior design schemes. Constructed for long-term heavy use, the chair features a 2.5mm thick powder-coated cold-rolled steel main support beam, paired with 1.5mm thick die-cast aluminum legs and polished aluminum alloy armrest frames. Each seat and back is upholstered in integral-skin black polyurethane (PU) over a bent plywood substrate, with wood-tone edge trim for a refined finish. The two end armrests house integrated charging modules set in durable ABS plastic housings, while four adjustable chrome-plated steel floor glides with non-slip rubber pads compensate for uneven floor surfaces; zinc-plated steel expansion bolts are included for permanent floor anchorage to prevent unwanted displacement. Practical features are tailored to public use demands: each end armrest integrates USB-A, USB-C, and AC power outlets delivering 20W per port, with built-in over-current and short-circuit protection to safeguard connected devices. The non-porous PU upholstery supports quick wipe-down cleaning with neutral detergent, and individual seat and back panels can be replaced without full unit disassembly to simplify long-term maintenance. The unit supports a static load of 150kg per seat, with a total unit static load capacity of 450kg. This seating solution is well suited for a wide range of commercial and public spaces, including airport terminal waiting zones, hospital and clinic reception areas, rail and bus station passenger waiting areas, government service hall waiting zones, corporate lobby visitor areas, and bank or service outlet customer spaces, where durable fixed seating and integrated device charging support improved user experience during extended wait times. For procurement planning, note that each unit ships across two cartons, with a reference assembly time of 40 minutes per set. The fixed floor-mounted design is intended for permanent installation, so teams should confirm site floor compatibility with the included expansion bolts prior to purchase. For high-volume orders, logistics teams can reference the 20GP container loading capacity to plan inbound freight efficiently.
