FAQs

How do I know if my chair is set up correctly?

If your feet are flat, knees at 90 degrees, back supported, and shoulders relaxed, your setup is likely correct. Discomfort is a sign adjustments are needed.

Should my chair be higher than my desk?

No. Your chair height should allow your elbows to align with the desk surface. If not, adjust the desk or chair accordingly.

Is lumbar support necessary?

Yes. Lumbar support maintains the natural curve of your spine and prevents lower back strain during long sitting periods.

How often should I change my sitting position?

You should shift position every 30–60 minutes. Even with a perfect setup, movement is important for circulation and comfort.

Can I improve comfort without buying a new chair?

Yes. Adjusting your current chair and adding accessories like monitor arms or footrests can significantly improve comfort.

What is the best chair for long hours?

Ergonomic chairs with multiple adjustment points are best. They allow you to customise support and maintain proper posture throughout the day.

Do armrests need to be used?

Not always. If armrests cause shoulder tension, adjust or remove them. They should support your arms without affecting posture.
