Size guide
Which height should you choose?
The height of your chair should generally be based on your own height. For example, if you're a woman measuring 168 cm, we recommend a medium setting. Exceptions may of course apply depending on where and how you intend to use the chair.
You have to because..
The seat is specially designed to keep your pelvis and spine straight so you don’t slouch as you would do in an ordinary chair.
The chair helps all the central muscle groups to have full mobility. It might take you a few weeks to train your back muscles, but it is worth the effort, and for every day sitting on your chair, you will feel that you are getting stronger and stronger in your core muscles.
The core muscles, also called the body's trunk, consists of deep muscles that support the spine and pelvis, ie. primarily the muscles around the abdomen and back.
Sit Strong
A strong body trunk is the whole foundation for virtually all the movements you make in everyday life and it has a huge impact for your well-being. Without strength in this part of your body you will collapse in the back, get a bad posture and the possibility of getting other problems is huge.
