2. Breakthrough Design in Lumbar Support Technology
The chair is equipped with the ZeroG Flow Dynamic Lumbar Support System, which combines three core technologies to achieve precise support:

• BackFit Four-Way Back-Lumbar Fit: Supports up-down and front-back adjustments to fit the lumbar positions of users with different body types;
• S-Flex Dynamic Spinal Pressure Distribution: Distributes pressure to the shoulders, back, lumbar region, and sacrum through a curved design, avoiding excessive local stress;
• FullSup Full Back Support: Provides continuous support to the back with a large curved surface, reducing the feeling of suspension.
  Test data shows: Lumbar pressure is reduced by 110%, lumbar muscle support is increased by 115%, support fit is improved by 85%, and the risk of lumbar injury is reduced by 92%, significantly reducing fatigue and injury risks from prolonged sitting.

3. All-Scenario Adjustment Functions

• Lumbar Support: Four-way adjustment to fit different sitting posture needs;
• Headrest: Supports approximately 8cm height adjustment and 40° rotation to fit the neck curve;
• Armrests: Adjustable in height up and down to relieve arm pressure;
• Backrest: 135° infinite recline with lockable angles, covering office, study, and rest scenarios.
  The adjustment logic is based on ergonomic principles, ensuring users receive support in different postures.

4. Quality and Durability Verification
The entire chair has passed over 50 rigorous tests, including gas lift pressure resistance tests and chassis load-bearing tests. Core components (such as the gas lift and chassis) are made of high-strength materials, ensuring long-term stability. Its hardware is sturdy and can withstand frequent adjustments and long-term weight-bearing, making it suitable for long-term use in home or office settings.

5. Price and Positioning Advantages
With a reference price of ¥399, it is evaluated as a 'hundred-yuan alternative to Herman Miller', with complete lumbar and back support configuration and high cost-effectiveness as its core competitiveness.
