Product Description

The Unbranded STK-PL-047 Stackable Ventilated Plastic Meeting Chair is a purpose-built office conference chair designed to balance functional durability, space efficiency, and user comfort for a wide range of public and commercial seating applications. Visually, the chair features a streamlined armless form defined by clean, angular lines, with a matte black powder-coated steel frame, structured ventilated backrest, and black woven fabric seat that coordinates seamlessly with neutral commercial interiors. Its fixed non-reclining seat and back angle supports upright seated posture tailored for focused group settings, with integrated molded PP armrests formed directly on front frame supports at a natural seated elbow height. The chair’s overall dimensions measure 575 x 445 x 850 mm, with a 540 mm clear width between armrests and a 240 mm tall lumbar support zone aligned to the lower back for extended sitting comfort. Built for consistent high-use environments, the chair combines robust, thoughtfully selected materials: an injection-molded polypropylene backrest with vertical ventilation slits to promote continuous airflow, a 90 mm thick upholstered padded seat with a high-resilience polyurethane foam core set over a 14 mm bent plywood internal support board, and a 1.5 mm thick matte black powder-coated steel tube frame reinforced with steel bracket hardware connecting the seat to the frame. The 70 mm thick backrest includes a 14 mm bent plywood or composite reinforced internal frame for structural stability, while legs are fitted with non-slip, non-marking injection-molded polypropylene caps to protect hard floor surfaces from scuffs. The seat upholstery delivers 30,000 cycles of abrasion resistance, and the chair supports a maximum user weight of 150 kg, with high-resilience seat foam providing 65% rebound for long-session comfort. Key practical features center on flexible, space-conscious deployment: the stackable design allows legs to nest vertically to hold a maximum of 15 units per stack, enabling fast, compact storage when seating is not in use. The non-reclining fixed angle maintains consistent posture appropriate for group events and formal meetings, while integrated ventilation prevents heat buildup during multi-hour sessions. The chair is suited for multiple commercial and public spaces: permanent conference room seating in offices and training facilities, temporary training classroom setups that require rapid deployment and breakdown, public visitor waiting and reception areas, and temporary event seating for exhibition halls and community gathering spaces. It is recommended for daily use of up to 8 hours, subject to independent ergonomic validation, and pairs appropriately with 2.4 m executive desks for formal meeting configurations. For procurement planning, note that each chair ships in two cartons with a total packaged gross weight of 23 kg and total carton volume of 0.26 m³, requiring 40 minutes of assembly per unit. At 85% space utilization, a 20GP shipping container can hold 135 sets, supporting scalable bulk orders for large venue fit-outs or multi-site deployments.
