Recommended high-cost-performance office chairs under 600 yuan: Sihoo-M18, Bajijian-Fourth Generation Student Version, Hbada-Smart Style, Gedeli-Latex Version, Lianqu-Vertical Double-Back Version, Kallewei-Black and White Version. Here are detailed analyses and purchasing suggestions:

I. Core Product Recommendations

1. Sihoo-M18

   • Support: Equipped with a fixed lumbar pillow, it effectively relieves lower back pressure during prolonged sitting, suitable for long-term office scenarios.
   • Adjustability: The headrest supports height and angle adjustments, accommodating users of different heights; the backrest can recline, meeting the need for short breaks.
   • Material: The mesh backrest offers excellent breathability, while the sponge seat cushion balances comfort and support.

2. Hbada-Smart Style

   • Ergonomic Design: The backrest fits the natural curve of the spine, reducing the feeling of lower back suspension, suitable for light office work or home use.
   • Material: Made of breathable mesh fabric, it remains cool in summer; the armrests are fixed, providing basic functionality.

3. Gedeli-Latex Version

   • Differentiated Experience: The seat cushion is made of latex material, offering superior softness compared to ordinary sponge, suitable for users who pursue comfortable seating.
   • Safety: The gas lift has passed SGS certification, ensuring basic safety.

4. Lianqu-Vertical Double-Back Version

   • Waist Optimization: The double-back design disperses pressure and dynamically fits waist movements, suitable for users who need to frequently adjust their sitting posture.
   • Cost-Effectiveness: It offers upgraded lumbar support at the 600-yuan price point, balancing functionality and price well.

II. Key Selection Criteria

1. Lumbar Pillow Support

   • Prioritize fixed lumbar pillows (such as Sihoo M18) or adjustable lumbar supports (such as Hbada P2 Pro's 4D lumbar support), avoiding models without lumbar pillows or with insufficient support.
   • For long-term sitting, pay attention to the elastic feedback of the lumbar pillow to avoid excessive pressure from being too hard.

2. Headrest Adjustability

   • The headrest should support height and angle adjustments to accommodate different heights and sitting postures (such as adjusting the headrest angle when reclining for a rest).
   • Models without a headrest or with a fixed headrest may increase cervical spine pressure and should be chosen with caution.

3. Material and Breathability

   • Mesh material (such as Hbada P2 Pro's Fusion dual-mesh system) offers better breathability than sponge but requires attention to elastic degradation after long-term use.
   • Sponge seat cushions are suitable for winter or air-conditioned environments but should choose high-density sponge to avoid sagging.

4. Safety Certification

   • The gas lift should pass SGS, TUV, or BIFMA certification to ensure explosion-proof safety (all tested models meet basic standards).

III. Budget Expansion Suggestions

If the budget can be slightly increased to 600-800 yuan, consider the following upgraded models:

• NetEase Yanxuan S9 Pro+: High-elastic breathable mesh fabric + adjustable lumbar support, suitable for summer or users who sweat easily.
• Hbada P2 Pro: 4D lumbar support + dual-mesh material, offering better long-term support and breathability.
