This height-adjustable classroom desk and chair set features 3-level adjustment on both the desk and chair, allowing precise ergonomic matching for students of different sizes. The desk offers a spacious 700×515×18mm desktop, a 520×210×18mm book basket, and a 520×280×18mm front modesty panel — all constructed from particle board with double-sided fireproof laminate and PVC edge banding for excellent scratch, heat, and moisture resistance. The desk height is adjustable across three levels: 640mm, 700mm, and 760mm. The desk frame is constructed from 25×1.0mm round tubes for the upper frame and 32×1.2mm round tubes for the lower frame. The matching chair features a 370×380×10mm seat and 380×160×10mm backrest — both made from plywood with fireproof laminate on the top surface and eco-friendly clear varnish underneath for a clean, durable finish. The chair height is adjustable across three levels: 380mm, 420mm, and 460mm. The chair frame uses the same 25×1.0mm upper tubes and 32×1.2mm lower tubes. 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 adjustable ergonomics, durable construction, and practical design to deliver reliable performance in diverse educational environments.
