The OK-519 adult student classroom chair is meticulously engineered to provide reliable, single-seat accommodation for higher education facilities and professional training environments. Combining a smoothly contoured, integrated injection-molded polypropylene (PP) shell with a precisely welded four-leg steel frame, this seating solution delivers exceptional structural integrity and physical support for adult learners. Designed specifically for the high-frequency usage typical of university lecture halls, vocational institutes, and adult education centers, the chair offers a tactile, easy-to-clean surface and a highly stable foundation. Its streamlined, armless silhouette not only maximizes spatial efficiency but also facilitates rapid venue reconfiguration, making it an optimal choice for large-scale educational project layouts requiring both physical resilience and adaptable room management.
With a meticulously calculated 49 cm seat height and an 80 cm overall profile, this chair perfectly accommodates the physical proportions of adult students. The curved backrest aligns with the natural spine contour, mitigating fatigue during extended university lectures or intensive vocational training sessions.
The one-piece injection-molded polypropylene seating surface offers a subtly textured finish that resists visible scratching while providing a comfortable, supportive cradle. Built for the relentless daily traffic of educational centers, the non-porous material prevents stain absorption and allows for rapid wipe-downs.
Engineered for absolute stability, the solid four-leg steel frame eliminates wobbling. Finished with a premium grey electrostatic powder coating, the metal surface feels cool and smooth to the touch while actively repelling moisture, resisting impact abrasions, and extending the operational lifespan of the seating unit.
Weighing a mere 4.5 kg per unit, the OK-519 empowers facility staff to effortlessly lift, reposition, and organize seating layouts. The open, armless design further enhances spatial efficiency, allowing users to enter and exit easily without disrupting adjacent rows in tightly packed lecture halls.
Maximizing container space, the chair’s structural profile allows approximately 1,200 units to be loaded into a single 40HQ container. This high-density packing capability directly translates to reduced shipping overhead and streamlined procurement for large-scale institutional upgrades.
Devoid of complex mechanical joints or fragile moving parts, this seating solution drastically cuts down on routine maintenance. Facility managers benefit from a straightforward, durable construction that demands minimal upkeep resources over years of continuous deployment.
To ensure complete transparency and precise spatial planning for your educational facility, the following data sheet outlines the exact physical dimensions, material composition, and structural properties of the OK-519 model. Facility managers and procurement officers can rely on these standardized metrics to verify spatial compatibility, assess physical footprint, and confirm material specifications prior to initiating large-scale institutional orders. Every measurement, from the 49 cm seat height to the 4.5 kg net weight, reflects our commitment to reliable, consistent manufacturing.

Securing large volumes of educational furniture requires predictable logistics and adaptable packaging solutions. The OK-519 is specifically optimized to support massive institutional rollouts, ensuring that the transition from the manufacturing floor to your university classrooms is highly organized and cost-effective. We prioritize high-density shipping configurations to maximize container yield, significantly lowering the per-unit transit expenditure.
Product Structure: The product consists of a unified PP seat-and-back shell securely anchored to the four-leg steel frame via heavy-duty screws, ensuring immediate structural integrity upon final setup.
Packing Method: Depending on your labor availability and transit preferences, we offer either fully assembled protective packing for immediate deployment or knock-down carton packing to maximize shipping density. The final method will be confirmed prior to formal quotation.
40HQ Loading Quantity: Engineered for spatial efficiency, a standard 40HQ container accommodates approximately 1,200 chairs, subject to the selected packing configuration, making it highly economical for bulk procurement.
Standard MOQ: Standard minimum order quantities remain flexible and will be precisely calculated based on your requested color palettes, chosen packaging style, and overall project scale.
Production Lead Time: Accurate manufacturing lead times will be established immediately once your specific color choices, total quantity, packing preferences, and payment terms are officially finalized.
Recognizing that every university, vocational school, and training institute possesses a unique visual identity, the OK-519 offers comprehensive aesthetic adaptability. We empower procurement teams to align the physical seating environment with their institution's branding guidelines, transforming standard classrooms into cohesive, professionally branded educational spaces. Our manufacturing process accommodates specific design modifications to meet exact project requirements.
PP Shell Color Matching: The integrated PP seat-and-back shell can be color-customized to reflect your institution's primary colors, creating a vibrant and engaging atmosphere for adult learners.
Metal Frame Finishes: Select from various surface treatments and color options for the steel frame, ensuring the electrostatic powder coating complements the surrounding interior architecture.
Institutional Logo Integration: Enhance brand visibility by applying your distinct university or training center logo directly onto the chair shell or the exterior packaging, reinforcing professional identity.
Tailored Packaging Solutions: Beyond standard shipping, we can engineer custom packing arrangements designed to meet specific warehouse handling requirements or regional distribution protocols.
All bespoke modifications, color codes, and branding applications will be thoroughly evaluated and confirmed based on your anticipated order volume and our current production capabilities.
To maintain the highest standards of safety, accuracy, and operational reliability, all procurement evaluations for the OK-519 must adhere to strict verification protocols. We ensure that every piece of data, from physical dimensions to compliance documentation, is transparent, authentic, and exclusively tied to this specific model. This rigorous approach guarantees that your educational facility receives exactly what is specified, without any misleading crossover data from alternative product lines.
Strict Model Independence: All provided parameters, load capacity evaluations, and loading density metrics apply exclusively to the OK-519. We prohibit the cross-application of data from other seating models to ensure complete accuracy.
Precise Dimension Verification: The physical footprint and spatial requirements must be validated against our official production dimension drawings. Critical measurements are strictly bound to the approved engineering blueprints.
