OK-505NB
OKBUY
The OK505 stackable plastic conference chair is a versatile, commercial-grade seating solution engineered to meet the rigorous demands of high-usage public and private spaces. Developed as a universal seating option for educational institutions, corporate conference centers, religious venues, event rental companies and government facilities, this chair balances exceptional durability, user comfort, space efficiency and customizable functionality to adapt to diverse application scenarios.
At the core of the OK505’s design is its integrated injection-molded polypropylene (PP) seat-and-back shell, a one-piece construction that delivers superior impact resistance, long-term structural stability and effortless daily maintenance. The smooth, non-porous PP surface is easy to wipe clean and sanitize, making it ideal for high-traffic environments where hygiene and quick turnaround between events are critical. The ergonomic contour of the seat and backrest provides optimal support for extended periods of sitting, reducing user fatigue during long training sessions, conferences or events.
Complementing the durable PP shell is a robust four-leg frame, available in two high-quality material options: heavy-gauge steel or genuine stainless steel. The steel frame can be finished with electrostatic powder coating in black or gray, or polished chrome plating for a sleek, modern aesthetic, while the stainless steel option offers exceptional corrosion resistance for outdoor use or humid indoor environments such as aquatic centers or coastal venues. The frame is available in two steel tube specifications – Ø22×1.1mm standard tube or Ø19×1.0mm optional tube – allowing customers to select the perfect balance of weight, strength and cost for their specific project needs.

One of the OK505’s most valuable features is its space-saving stackable design, which supports vertical stacking of up to 15 chairs. This capability drastically reduces the storage footprint required when the chairs are not in use, and simplifies rapid setup, breakdown and transportation for event rental companies, multi-purpose venues and training facilities that frequently reconfigure their seating layouts. For venues requiring fixed, orderly row seating, the OK505 offers two optional interlocking connection systems: a welded frame-mounted built-in connector, or a detachable external row connector. Both options allow chairs to be securely linked together in straight or curved rows, preventing movement and ensuring a uniform, professional appearance in auditoriums, churches, conference halls and performance venues.
