This three-seat classroom desk and chair set is designed for efficient, space-saving learning environments. The set includes one long desk (142cm wide × 42cm deep × 75cm high) and three matching chairs. The desk comfortably accommodates three students, with each student receiving approximately 47cm of personal workspace — ideal for textbooks, notebooks, and stationery. The desk surface is constructed from 18-25mm thick density board with double-sided melamine lamination and PVC edge banding (or solid wood plywood) for excellent scratch and moisture resistance. The sturdy steel frame features 30×50mm or 40×40mm main tubes (1.0-1.5mm wall thickness) with a durable electrostatic powder-coated finish for rust and scratch protection. Each chair features a 40cm seat height with PE hollow blow-molded (or PP injection molded) seat and backrest — lightweight yet durable. The chair frames are constructed from 20×40mm or 25×25mm steel tubes with the same powder-coated finish. Anti-slip nylon glides on both desk and chairs ensure stability on various floor surfaces while preventing scratches. This set combines durable construction with comfortable ergonomics, making it the ideal choice for schools, training centers, and institutional learning spaces.

School Classrooms
The 142cm wide desktop accommodates three students side by side, maximizing seating capacity in standard classroom layouts. Each student has approximately 47cm of personal workspace — sufficient for textbooks, notebooks, and writing materials. The 40cm seat height and 75cm desk height promote proper posture for primary and secondary school students.
Training Institutions & Tutoring Centers
The three-seat configuration encourages collaborative learning and group discussions. The durable PE/PP seat surfaces resist stains and are easy to clean. The steel frames withstand daily use in high-turnover training environments. The neutral design suits various classroom aesthetics.
Libraries & Study Halls
The compact 142cm width fits standard library tables and study carrels. The comfortable seat height and ergonomic backrest support extended study sessions. The scratch-resistant desktop surface protects against daily wear from books, laptops, and writing instruments.
Exam Halls & Multi-Purpose Rooms
The three-seat set can be arranged in rows for examinations or clustered for group activities. The 75cm desk height works with standard exam papers and laptops. The anti-slip glides keep furniture in place during use, while allowing easy repositioning for room reconfiguration.
This set accommodates three students simultaneously — each with a dedicated chair and approximately 47cm of personal desktop space. The 142cm total width provides comfortable elbow room for three average-sized students.
The desk height is fixed at 75cm, which is the standard height for secondary school and adult learning environments. The chair seat height is 40cm, providing an ergonomic 35cm desk-to-seat height differential. This configuration is suitable for students approximately 140-180cm tall. For primary school applications, we recommend our adjustable-height models.
The desktop is made from 18-25mm thick density board with double-sided melamine paper and PVC edge banding (or solid wood plywood, depending on model) — offering excellent scratch, moisture, and impact resistance. The chair seat and backrest are made from PE (hollow blow-molded) or PP (injection molded) plastic — lightweight, durable, and easy to clean.
