Recommended Office Chair Brands

According to existing search results, mainstream office chair brands include Hbada, Guquan, Ergonor, JD.COM Jingzao, and Yongyi. These brands excel in ergonomic design, material durability, and user reputation. For example, Ergonor's Jinhao series is renowned for its separate lumbar and back support technology, suitable for long hours of office work; Yongyi's UE series features breathable mesh fabric and adjustable headrests, ideal for summer use.

Key Selection Factors

1. Ergonomic Design
   Prioritize models with adjustable headrests, lumbar supports, armrests, and seat depths to accommodate different heights and body types. For instance, the lumbar support should be adjustable up and down or forward and backward to ensure precise support for the lumbar spine and reduce fatigue from prolonged sitting.

2. Material and Breathability
   Mesh fabric offers better breathability than leather, making it suitable for extended use; leather seats are easier to clean but should feature perforated designs for better ventilation. High-density foam is recommended for seat cushions to prevent sagging.

3. Safety of Gas Lift and Five-Star Base
   The gas lift should be certified by international standards such as SGS or TUV to ensure smooth height adjustment; the five-star base is recommended to be made of aluminum alloy or nylon reinforced with fiberglass for stronger load-bearing capacity.

4. Brand and After-Sales Service
   Prefer brands that offer at least a 3-year warranty and confirm whether on-site repair services are included. For example, some models from JD.COM Jingzao support a 30-day no-reason return policy, reducing the cost of trial and error.

Tips to Avoid Pitfalls

• Avoid purchasing unbranded or counterfeit products, as they may pose safety hazards such as gas lift explosions or formaldehyde exceedance.
• Be cautious of 'low-price, high-specification' promotions. Products claiming to be 'ergonomic chairs' priced below 1,000 yuan often compromise on adjustable functions or materials.
