Questions about sitting actively

Our chairs are designed on the principle that you should sit in a balanced position and activate your muscles. This means that you strengthen your body, because you are activated and not locked into position. The chair helps you sit up straight and in balance.

You should choose a chair that makes you sit actively because you keep your body moving, thereby boosting your blood circulation. You avoid getting tired legs, a tense neck and back and you constantly get a fresh flow of blood to the brain, so you can perform at work without getting tired.

Without a backrest you train your core muscles and gain a better posture - and you won't even notice you're doing it.

The hump at the front of the seat prevents you from sliding off the chair. It ensures that you have a stable and balanced sitting posture - particularly in situations that require you to focus, when it's even more important that your chair supports you correctly.

If the 'hump' at the front annoys use, you might be sitting too high. Try lowering the height of the chair and see if that feels better.

People often say that if you sit on a traditional 'saddle' chair, you have to sit REALLY high up - but that's not true.

Technical questions and care

You can't lock the flex mechanism as the aim of the chair is to make you sit more actively. You will quickly get used to the chair following your movements.

Check for any dirt stuck on the wheels - and try vacuuming them. See more about how to care for your chair here. If necessary, you can buy new wheels in our webshop under accessories.

If your chair won't quite react as it should when you try to move it up or down, it may be because the piston in the cylinders has become 'dry'. If possible, pull the seat up to the highest position and clean the piston with domestic alcohol using a sheet of kitchen roll. Next, apply 5 drops of sewing machine oil (this must be ACID-FREE oil - NOT WD-40) onto the piston. Run the seat up and down a couple of times, wipe and add a little more. Your chair should now work.
