This height-adjustable classroom desk and chair set is engineered for durability, ergonomic comfort, and long-term reliability in active learning environments. The desk features a 600×450×18mm desktop made from density board with ABS injection-molded edge banding and double-sided decorative melamine paper — offering excellent scratch and moisture resistance. The desk height is adjustable from 670mm to 790mm to accommodate students of varying sizes. The 500×385×150mm book basket is made from PP virgin material through one-piece injection molding, providing sturdy, rust-proof, and ventilated storage for textbooks and supplies. The desk frame is constructed from 20×49×1.2mm oval tubes for the upper frame, 30×60×1.2mm oval tubes for the lower frame, and 20×40×1.2mm oval tubes for connections. The matching chair features a 400×355mm seat and 385×265mm backrest — both PP injection molded in one piece for durability, impact resistance, and easy cleaning. The chair height is adjustable from 360mm to 440mm. The chair frame uses 30×60×1.2mm oval tubes for the base and uprights, 20×49×1.2mm oval tubes for the lift sleeves, and 15×30×1.4mm oval tubes for the backrest support — with thicker 1.4mm wall thickness for enhanced backrest durability. All bottom fittings are made from high-quality nylon plastic with a rated friction resistance of ≥100,000 cycles, ensuring smooth, quiet movement and long-term durability. All steel components undergo acid pickling and phosphating pretreatment before powder coating, delivering high scratch resistance and superior corrosion protection. This set combines robust construction with ergonomic design to deliver reliable performance in demanding educational environments.
