Optimize your desk chair for comfort and posture.
45.5 cm
Adjust so your feet are flat on the floor and knees are at about a 90-degree angle. Use a footrest if needed.
47.3 cm
Ensure 2-4 fingers can fit between the edge of the seat and the back of your knees. This prevents pressure on your thighs.
70.0 - 87.5 cm
The backrest should support the natural curve of your spine, especially your lower back (lumbar region). For full support, it should reach your shoulder blades or higher.
35.0 cm
Adjust armrests so your arms are at about a 90-degree angle, with shoulders relaxed. This reduces strain on your neck and shoulders.
Proper ergonomic setup of your workspace, especially your chair, is vital for long-term health and productivity. A poorly adjusted chair can lead to back pain, neck strain, carpal tunnel syndrome, and reduced circulation.
By ensuring your chair fits your body correctly, you can maintain a neutral posture, reduce physical stress, and improve your overall comfort and well-being during long hours of sitting. This tool provides general guidelines; individual preferences and specific chair features may require further fine-tuning.
