Description
ONMUSE develops school furniture solutions for modern teaching and learning environments. This modular classroom desk and chair system is designed for schools, universities, lecture rooms, study centers, and mixed-age learning spaces where seating needs to be orderly, durable, and easy to manage.
By combining a fixed writing table with rotating seats, this system helps maximize the use of educational buildings and supports learning activities beyond traditional classroom layouts.
Modular Desk And Chair System For Learning Spaces
The AU-HS-3103 system consists of a fixed writing table and two mobile seats supported by reinforced steel pivoting arms. It can be arranged in multiples of two, in straight rows or curved rows, and installed on flat floors or wide steps.
This structure is especially suitable for conference rooms, auditoriums, universities, lecture rooms, and study centers that require a clean and consistent seating layout. Buyers looking for related classroom seating options can also view ONMUSE school desk and chair products.
360° Rotating Seat With Automatic Return
The seats are designed with 360° rotation and calibrated automatic return. This allows students to enter, leave, turn, and interact more easily, while the automatic return function helps keep the seating layout neat after use.
The seat support arm uses automatic spring return rotation with a 78° excursion, turning the desk system from a fixed study desk into a more flexible learning unit for group discussion, study, and training activities.
Desk, Frame And Cable Management Details
The main structure is made of cold-rolled carbon steel that is stamped, welded, ground, degreased, rust-removed, and electrostatically sprayed. This makes the system sturdy, durable, and resistant to rust and corrosion.
The internal frame allows communication cables to pass through, helping schools keep classrooms and lecture spaces cleaner and more organized. The top crossbeam provides support and added safety for the writing board.

Swing Arm Structure
The swing arm is made of high-quality die-cast aluminum alloy with anti-oxidation treatment and high-temperature spraying. This finish improves adhesion, corrosion resistance, rust resistance, and color stability for long-term use in schools, universities, lecture rooms, and training spaces.
A decorative cover is installed on the swing arm to hide the screw structure, creating a cleaner appearance while improving dust resistance and ease of cleaning. The cover is made of PA nylon reinforced with 25% glass fiber, providing high tensile strength, hardness, wear resistance, and heat resistance.
Writing Board Material & Finish
The writing board is made from 25 mm thick MDF. The board is cut and formed after drying, insect-proofing, and anti-corrosion treatment. Both sides are laminated with 0.8 mm fire-resistant boards from premium brands such as Wilsonart, Schiene, or equivalent options.
The edges are finished with PVC edge banding to improve durability and provide a cleaner finish for daily classroom use. This makes the desk surface suitable for fixed school desk and chair systems used in lecture rooms and study centers.
