A wider seat.
Avoid working in a static tensed posture for too long. With the Jumper chair you can move and relax as much as possible during your work. Sit upright in an active posture: push your chest out, which optimises blood circulation and breathing. Your body is able to work efficiently, delivering oxygen and nutrients around your body as well as getting rid of waste products like carbon dioxide. As soon as you start to sit in a healthy posture, you will automatically feel better and work more comfortable.
