OK-519 student chair
The OK-519 is a professional-grade adult student chair engineered to deliver reliable, long-lasting single-seat seating for higher education and training environments. Moving beyond basic functionality, it combines a sturdy integrated injection-molded polypropylene (PP) seat-and-back shell with a solid four-leg steel frame. This creates a seating solution that balances structural durability, effortless maintenance, and ergonomic comfort for adult users. When you run your hand along the shell, you will notice a subtly textured matte finish that not only prevents sliding during long lectures but also resists the daily scuffs and impacts typical of high-traffic academic settings. Its core design focuses on meeting the high-frequency use demands of university classrooms, vocational school training rooms, and adult education centers. Furthermore, the lightweight architecture simplifies venue arrangement, allowing facility staff to reconfigure spaces silently and swiftly, while the optimized dimensions streamline bulk project configuration and spatial planning.
With an approx. 49 cm seat height and 80 cm overall height, this chair is perfectly sized for adult students in universities, vocational schools, and adult training classrooms. The contoured backrest mimics the natural curvature of the human spine, delivering comfortable, targeted lumbar support that reduces physical fatigue and maintains user concentration during extended three-hour study sessions.
The one-piece injection-molded polypropylene (PP) seat-and-back shell is highly scratch-resistant and built to withstand frequent daily use in high-traffic educational environments. The non-porous surface repels spills and stains, making it exceptionally easy to clean and maintain with standard facility wiping protocols, ensuring classrooms always look pristine.
The solid four-leg steel frame provides reliable structural stability without any distracting wobbles or creaks. Finished with a grey electrostatic powder coating, the metal surface resists rust, peeling, and wear and tear, guaranteeing a long-term service life even under the rigorous demands of daily campus utilization.
At only 4.5 kg per chair, it enables effortless lifting, moving, and rearrangement by staff or students. This lightweight profile simplifies daily classroom setup, allowing a traditional lecture layout to be transformed into collaborative group circles in minutes, thereby maximizing flexible space management.
With an approx. 1,200 chairs per 40HQ container loading quantity, this chair is explicitly optimized for bulk education project procurement. This dense packing efficiency drastically reduces logistics costs and carbon footprint for large-scale venue configuration, optimizing your overall project budget.
PP seat/back color, metal frame color, logo application, and packing method can all be confirmed and customized according to your order quantity and production requirements. This ensures the seating perfectly aligns with your institution's visual identity and branding guidelines.
The simple, sturdy structure features no complex moving parts, hinges, or delicate mechanisms. This minimalist engineering minimizes maintenance needs, eliminating the need for constant tightening or lubrication, making it an incredibly cost-effective choice for educational institutions with limited upkeep resources.
The armless structure allows for easy, unrestricted entry and exit, accommodating users of various body types comfortably. It also facilitates flexible, space-saving seating arrangements, enabling chairs to be pushed closer together in classrooms and training rooms of any layout without the obstruction of armrests.
Understanding the exact physical parameters of your seating is crucial for accurate spatial planning and facility management. The OK-519 is engineered with precise dimensions to accommodate adult users comfortably while maximizing floor space efficiency. From the integrated injection-molded shell to the reinforced steel framework, every material and measurement listed below has been standardized to ensure consistency across large-scale deployments. Please review the comprehensive data sheet below for all critical specifications, including exact dimensions, material compositions, and structural details.
