II. Purchasing Suggestions

1. Matching Body Parameters

   • Seat Height: After adjustment, both feet should be flat on the ground, and the thighs should be parallel to the ground. If the chair cannot be adjusted, a footrest can be used as an aid.
   • Seat Depth: When sitting, there should be a gap of 2-3 fingers between the back of the knee and the front edge of the seat cushion to avoid compressing the leg blood vessels.
   • Backrest Height: The headrest should support the middle part of the cervical spine, and the highest point of the backrest should reach below the shoulder blades to provide complete back support.

2. Material and Function

   • Breathability: Prioritize mesh or perforated leather materials to reduce the feeling of stuffiness. For foam seat cushions, pay attention to the density (it is recommended to be ≥45kg/m³).
   • Adjustability: It should have at least 2D adjustment functions for the headrest, armrests, and lumbar support to adapt to different sitting postures (such as leaning forward for office work and leaning back for rest).

3. Usage Scenarios

   • Office Scenarios: Choose models with footrests or that can recline to more than 135° for convenient noon breaks.
   • Dormitory Scenarios: Prioritize lightweight, foldable, or armrest-flipping designs to save space. If long-term use is required, it is recommended to choose mid-to-high-end models to protect spinal health.
