Office Chair SG

"Office Chair SG" needs to be differentiated based on specific models or certification types. The two common types are the SG-07 model and SGS-certified products, with their features and purchasing recommendations as follows:

I. SG-07 Office Chair (Shiguang Furniture Product)

1. Material and Structure
   • The headrest and backrest are made of cowhide + cut cotton + curved plywood, and the seat is made of cowhide + shaped cotton + curved plywood, balancing support and comfort;
   • Equipped with a heavy-duty chassis (supporting 5-level locking), a TÜV Class 4 electroplated gas lift (passing safety certification), an aluminum alloy five-star base, and universal nylon wheels, the overall design leans towards durability, suitable for high-intensity usage scenarios.
2. Specifications and Customization
   • Supports customization of standard sizes and colors to meet personalized needs, but does not explicitly mention dynamic support or ergonomic details (such as lumbar support adjustment, seat depth adjustment, etc.).
3. Applicable Scenarios
   • Suitable for office environments with high requirements for material durability and long-term stable use. However, if long-term sitting with lumbar support or dynamic support functions are needed, the specific design needs to be further confirmed.

II. SGS-Certified Office Chairs

1. Certification Meaning
   • SGS certification primarily verifies product safety and durability (such as gas lifts needing to pass Class 4 testing), not directly equivalent to comfort. For example, a high-end chair with full certification was complained about for its rigid lumbar support and thigh-cutting seat cushion, indicating that certification is only a basic threshold.
2. Ergonomic Differences
   • Although mainstream ergonomic chairs in 2026 (such as Xiamumu Fit2 and Heibaidiao E3 Pro) have all passed SGS certification, there are significant differences in sitting comfort, mainly due to the dynamic adaptability of the lumbar support (such as the ZeroG 2.0 system and three-zone adaptive mechanical lumbar support).
   • Purchasing Recommendations: Prioritize attention to whether the lumbar support can be adjusted in multiple directions, whether the seat cushion adopts a zoned pressure-relief design, and whether the headrest supports height/angle adjustment, etc., to avoid relying solely on certification.

III. Comprehensive Purchasing Recommendations

1. Clarify Needs: If durability is required, choose the SG-07; if dynamic support is needed, confirm the ergonomic design of the specific model (such as lumbar support, seat cushion, and armrest adjustment functions).
2. Beware of the "Certification Trap": SGS certification only indicates that safety standards are met. Comfort needs to be combined with the actual design of the product (such as the lumbar support's ability to follow the waist and the resilience of the seat cushion material).
3. Test Sitting Experience: For long-term sitting scenarios, it is recommended to test sit offline, focusing on whether the lumbar support fits well, whether the seat cushion presses on the thighs, and whether the headrest matches the height.
