How can I test if an office chair provides adequate lumbar support?

To test an office chair for adequate lumbar support: 1. Sit down and lean back into the chair. 2. Check if the lumbar support fits snugly against your lower back, maintaining the natural inward curve of your spine. 3. Adjust the height, depth, and firmness of the support if the chair offers these features. 4. Ensure that you feel comfortable and that the support aligns well with your lumbar region without causing pressure points or discomfort.
