Our chairs are designed around the principle that sitting should engage your body, not hold it still. By encouraging a balanced sitting position, the chair activates your muscles, helping you to build strength and maintain good posture throughout the day. Rather than locking your body in place, it encourages an upright, natural posture that keeps you balanced and aligned.

You should choose a chair that encourages active sitting, because keeping your body in gentle motion boosts blood circulation. This helps to prevent tired legs and tension in your neck and back while ensuring a steady flow of oxygen-rich blood to your brain. The result? You will have greater focus, more energy, and the ability to perform at your best all day long.

Without a backrest, your core muscles are naturally activated. This improves your posture. You won't even notice it happening.

The raised front edge of the seat is designed to keep you in position and prevent you from sliding forward. This helps you to maintain a stable and balanced sitting posture, which is especially important during tasks that require focus and precision.

If the raised front of the seat is uncomfortable, you might be sitting too high up. Try lowering the chair slightly — it often makes a big difference!
Many people assume that you have to sit very high on a traditional saddle chair, but this is a misconception. The correct seat height will support your posture without causing discomfort or pressure.

If the height adjustment mechanism is not working properly, it may be that the gas lift piston has dried out.

Here’s what to do:
1. Raise the seat to its highest position.

2. Clean the exposed piston with a paper towel soaked in household alcohol.

3. Apply five drops of acid-free oil (such as sewing machine oil — do not use WD-40).

4. Move the seat up and down a few times.

5. Wipe off any excess oil and repeat if necessary.

This should restore smooth height adjustment.
