Introduction
Analysis of core technical requirements of the standard
| Technical indicators | Parameter requirements | Test methods | Physiological significance |
|---|---|---|---|
| Peak pressure of waist | 3-10kPa | Pressure distribution measurement system (accuracy 0.1kPa) | Prevent excessive compression of the lumbar spine |
| Waist-to-hip pressure ratio | 35%-70% | 4 testers with BMI20-25 | Maintain the natural curvature of the spine |
| Softness and hardness support | User experience evaluation | 10-person 5-point evaluation | Muscle relaxation level |
Key technology implementation points
Body pressure distribution measurement requires the use of pressure distribution measurement system. Note that during the test:
- The tester's BMI is strictly controlled in the range of 20-25
- Supine posture is standardized (legs naturally apart, arms crossed in front of the chest)
- The test environment requires a horizontal hard floor
Background analysis of standard formulation
This standard is based on the human body size data of Chinese adults (GB/T10000) and is formulated according to the sleep characteristics of Chinese people. Research shows:
- There is a 3-5° difference between the lumbar curvature of Asians and Europeans
- Weight distribution characteristics lead to different waist-to-hip pressure ratio thresholds
User Experience Implementation Specifications
Note the 11 evaluation dimensions specified in Appendix B:
- Brand information must be hidden before testing
- Each posture experience time ≥ 30 minutes
- Evaluation results must be converted into scores (excellent = 100 points, poor = 20 points)
