Product Description

This 3-seat beam public tandem waiting chair balances durable construction, functional design, and approachable aesthetic for high-traffic public settings. Visually, the unit features uniform molded blue polyurethane seat and back panels contrasted by a silver metal frame, with clean linear lines from the continuous central support beam and splayed Y-shaped aluminum legs. The layout includes only end-position armrests with no intermediate dividers, creating an open, unobstructed seating profile that fits seamlessly into professional public environments. At 1750 mm wide, 680 mm deep, and 880 mm tall, the chair’s proportions align with standard public space clearances, with individual seats offering 520 mm of width and a 435 mm seat height from the floor, and 510 mm backrests positioned to support upright seated posture. Each seat incorporates a contoured lumbar curve and waterfall front edge to reduce pressure during extended waits, while the open under-seat frame eliminates enclosed gaps for quick, unobstructed cleaning access. The non-porous seat and back surfaces wipe clean easily to resist staining, and the lead-free electrostatic polyester powder coating on all metal components delivers rust-proof corrosion resistance for long-term use. The welded beam structure supports a 900 kg total static load capacity, with each individual seat rated for 300 kg static load, and weld joints rated for 1200 kg static load to withstand regular high-volume use over a 20-year design service life. Construction includes 20mm thick self-skin molded polyurethane seat and back panels with integrated steel inserts and 14 mm bent plywood internal support, mounted to a 2.0mm wall thickness hexagonal steel support beam via 1.5mm thick stamped steel brackets secured with Grade 8.8 zinc-plated steel bolts and lock washers. The 2.0mm thick die-cast aluminum end armrests sit 220 mm above the seat surface, matching the silver nano-sparkle powder coat finish of the splayed Y-shaped aluminum alloy legs, which terminate in 50mm diameter anti-slip nitrile rubber glides with adjustable leveling bases. The unit is free-standing for quick placement, with optional bolt-down fixation available for permanent installations, and individual seat, back, armrest, and leg components are bolt-replaceable to simplify long-term maintenance. This seating is suited for transit hubs, healthcare clinic waiting areas, government service lobbies, corporate reception zones, and educational institution common areas, pairing well with a 2.4 m executive desk for reception counter use with a reference daily use duration of 8 hours, subject to ergonomic confirmation. Procurement teams should note the set ships in two cartons with a total packaged gross weight of 23 kg, requires 40 minutes of assembly per unit, and should evaluate floor surface conditions to select between free-standing glide placement or bolt-down mounting for site-specific stability needs. No intermediate armrests are included, so teams should confirm seating layout needs align with the open 3-position configuration prior to purchase.
