Product Description

The Stackable Armless Office Meeting Side Chair (model STK-PP-460SEAT) is an unbranded public seating solution designed for flexible, high-use commercial environments. It features a clean, streamlined armless silhouette with a contoured curved backrest and a neatly proportioned upholstered seat, finished in a modern understated aesthetic that suits a wide range of professional interiors. Its profiled splayed legs enable neat vertical stacking, with a maximum stack height of 36 chairs to minimize occupied storage space when not in use. Dual integrated cutout handles at the lower back allow for easy two-hand transport during space reconfiguration. Built for consistent long-term use, the chair’s backrest is constructed from injection-molded virgin PP engineering plastic, reinforced by an internal molded rib structure for stable structural support. The seat is anchored by a 14 mm bent plywood support panel set into a molded PP seat pan, topped with high-density polyurethane foam that meets a 45 kg/m³ density rating and 5.5% compression set for lasting shape retention. The seat is upholstered in woven commercial polyester fabric rated for 50,000 double rubs of abrasion resistance, with a curved 50 mm thick waterfall front edge. The frame is fabricated from 1.5 mm thick cold-rolled steel tube, finished with electrostatic powder coating to resist daily wear, and fitted with replaceable injection-molded nylon floor glides that prevent surface scratching. The chair holds a static seat load capacity of 204 kg, with a frame static load rating of 150 kg, and weighs 9.7 kg per unit. It offers fixed non-adjustable seating angles, a contoured lumbar curve for ergonomic support, and compatibility with optional nylon ganging clips to secure connected rows of seating. This chair is well suited for office conference rooms, as its stackable armless form supports flexible seating layouts for meetings. It works effectively in training and seminar spaces, where its integrated carry handles allow fast repositioning between sessions. Its clean aesthetic fits reception and waiting areas, while its durable build supports high-traffic temporary seating in public event venues. The compact footprint maximizes seating density in co-working open spaces, and its easy-clean fabric and sturdy frame suit casual daily use in breakrooms and cafeterias. Fixed dimensions include an overall size of 480 x 545 x 880 mm, a 460 mm seat height, 445 mm seat width, and 470 mm backrest height above the seat. For procurement, note that each unit ships across 2 cartons with a total packaged gross weight of 23 kg, requires 40 minutes of assembly per set, and supports loading of 135 sets in a 20GP container at 85% space utilization. Replacement glides and compatible ganging clips should be factored into orders for spaces requiring connected row seating or long-term maintenance planning.
