II. General Recommendations for Selecting Office Chairs

If users are concerned about the functionality or quality of the 'Yishang Office Chair', they can refer to the following key points for selecting ergonomic office chairs:

1. Load-Bearing Structure
   Prioritize products with high-strength steel or aluminum alloy frames to ensure no deformation during long-term use. The chassis should have an explosion-proof design to avoid the risk of air pressure rod failure.

2. Material Selection

   • Mesh Fabric Material: Good air permeability, suitable for long-term sitting, but attention should be paid to elasticity and durability.
   • Seat Cushion Material: High-density foam or memory foam can provide good support, avoiding lower back fatigue caused by seat cushion collapse.

3. Adjustability
   Adjustable headrests, lumbar supports, armrests, and seat heights are crucial. Multi-dimensional adjustability can accommodate users of different body types and reduce discomfort from prolonged sitting.

4. After-Sales Support
   Choose brands that offer long-term warranties (e.g., over 5 years) and rapid response services to ensure convenience in product maintenance and repair.
