Frequently Asked Questions

Key metrics include pressure mapping, spinal alignment measurements (using X-rays or posture analysis tools), subjective comfort ratings (using questionnaires or scales), and electromyography (EMG) to assess muscle activity.
Pressure mapping uses sensors to measure the distribution of pressure between the users back and the chair. It helps identify areas of high pressure, indicating poor support, and ensures even pressure distribution for optimal comfort.
Spinal alignment measurements typically involve assessing the lumbar curve (lordosis) using X-rays or posture analysis tools. Effective lumbar support should maintain or improve the natural curvature of the spine.
Subjective comfort ratings involve using questionnaires or scales (e.g., Visual Analog Scale) where users rate their comfort level and perceived support. These ratings provide valuable insights into the users experience and satisfaction.
Electromyography (EMG) measures the electrical activity of muscles in the lower back. It helps assess muscle fatigue and strain, indicating whether the lumbar support is effectively reducing muscle effort and promoting relaxation.
Look for armchairs that provide even pressure distribution (as shown by pressure mapping), promote healthy spinal alignment, receive high subjective comfort ratings, and demonstrate reduced muscle activity in the lower back via EMG.
