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 400×600×18mm 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 450×300×150mm book basket is constructed from 0.7mm galvanized steel sheet through one-piece stamping, featuring small holes on both sides for ventilation and easy visual identification of contents. The desk frame features 20×49×1.1mm oval tubes for the upper frame, with 25×25×1.0mm square tube under-desktop support, and 30×60×1.2mm oval tubes for the lower frame with 20×49×1.1mm connecting bars for structural integrity. An ABS backpack hook rated for loads ≥10KG provides convenient bag storage. The matching chair features a 400×370mm seat and 400×220mm backrest — both made from PE hollow blow-molded material through one-piece molding, offering excellent impact resistance, lightweight durability, and easy cleaning. The chair height is adjustable from 380mm to 430mm with a total height of 790mm. The chair frame uses 20×49×1.1mm oval tubes for the upper frame, 30×60×1.2mm oval tubes for the lower frame, 20×49×1.1mm connecting bars, 15×30×1.5mm oval tubes for under-seat support, and 20×40×1.2mm oval tubes for backrest support. 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.
