When evaluating desks, prioritize material durability and structural integrity. For wooden desks, ensure the use of E1 or E0 grade MDF/Particle Board to meet formaldehyde emission standards, or solid wood with kiln-drying treatment to prevent warping. For height-adjustable desks, verify the motor lifting capacity (minimum 80kg-120kg) and noise levels (below 50dB). Additionally, check for powder-coated steel frames with a thickness of at least 1.2mm to ensure long-term stability under heavy office equipment loads.
