OK-505chair insert writing pad screwed bookrack

Product Overview

The OK-505DNS (OK-505chair insert writing pad screwed bookrack) is a professional-grade seating solution engineered specifically for high-frequency educational and commercial environments. By integrating a meticulously contoured, injection-molded polypropylene (PP) shell with a fixed writing tablet, this chair completely eliminates the need for bulky traditional desks. The ergonomic backrest is designed to trace the natural curve of the human spine, delivering exceptional lumbar support that significantly reduces physical fatigue during prolonged lectures or seminars. Supported by a heavy-duty, four-leg steel frame, it offers a highly stable foundation while maintaining a surprisingly lightweight profile. The tactile surface of the PP shell feels smooth yet resilient, while the matte finish of the writing pad prevents distracting glare under overhead lighting. This space-optimizing design allows facility managers to maximize seating density without compromising individual comfort, making it an indispensable asset for modern training centers, multipurpose halls, and dynamic learning spaces.

Key Features

• Integrated Fixed Writing Tablet for Space Optimization: Equipped with a built-in fixed writing tablet measuring approx. 40 × 30.5 cm, positioned ergonomically at a height of approx. 73.5 cm. This matte-finished surface provides a highly stable foundation for heavy textbooks and laptops, entirely eliminating the spatial footprint of traditional separate desks.

• Ergonomic One-Piece PP Seat & Back Shell: Constructed from thickened, integrated injection-molded polypropylene (PP) plastic, the backrest is contoured to support the human spine. It reduces fatigue during long sessions, while the tactile, impact-resistant surface remains incredibly easy to wipe clean after daily institutional use.

• Heavy-Duty Four-Leg Steel Frame: Engineered with a black four-leg steel foundation that includes a dedicated, reinforced support structure for the writing pad. This structural integrity guarantees unwavering stability, preventing distracting wobbles during intense writing or typing activities.

• Ultra-Lightweight 4.8kg Mobility: Despite its heavy-duty capacity, each chair maintains a net weight of only 4.8 kg. This lightweight profile empowers a single facility staff member to effortlessly lift, move, and rapidly reconfigure seating arrangements for dynamic seminar layouts.

• Exceptional Load Capacity: Rated for an impressive load capacity of 600 lbs (approx. 272 kg), subject to OK-505DGS-specific test or applicable documentation. This commercial-grade strength ensures absolute reliability and structural safety for diverse user demographics.

• Space-Saving Ergonomic Dimensions: Designed with optimized dimensions featuring an overall height of 80 cm and a comfortable seat height of 44.5 cm. This carefully calculated geometry maximizes your venue's seating density without compromising the individual comfort of the attendees.

• Anti-Scratch Black Powder Coating: The metal frame is treated with a premium black electrostatic powder coating finish. This process creates a remarkably smooth, scratch-resistant exterior that effortlessly withstands the friction of frequent stacking, daily use, and rigorous cleaning protocols.

• Customizable Color Configurations: Offered in a visually striking standard configuration of a green PP shell, black tablet, and black frame. To perfectly align with your organization's visual identity, an extensive palette of alternative color options is readily confirmable based on your specific order requirements.

• Multi-Dimensional Application Range: An exceptionally versatile seating solution perfectly suited for school training rooms, multipurpose corporate classrooms, expansive training centers, and various commercial seminar venues requiring a highly functional, all-in-one seating setup.

• Comprehensive OEM/ODM Customization: Fully supports bespoke customization encompassing PP shell color, tablet finish, frame color, precision logo application, and optimized packing methods. This ensures the final product not only matches your venue branding but also maximizes logistics efficiency.
