The matching chair features a 400×350×18mm seat and 400×220×18mm backrest — both made from density board with ABS injection-molded edge banding and double-sided decorative melamine paper for consistent quality and appearance. The chair has a fixed overall height of 740mm, with the frame constructed from 20×49×0.9mm oval tubes for the lower frame and 20×20×1.2mm square tubes for the 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.
