The Fehn’s patented ergonomic Standing Desk Seat is the key to comfort.  It rotates your pelvis to the correct angle so your spine assumes its natural curvature. It’s not forced into one position the way conventional seats will.   Your spine is fully supported without the need for a backrest, freeing you to stretch back and move around without limitation.  The rocking seat and multiple footrests encourage dynamic movement.   Your spine can remain in the precise shape and relieve muscle stress by 40-90%.  When sitting or standing in a single position for a long period of time, you tend to reduce the blood supply to your muscle tissue. Insufficient circulation causes fatigue and increases your risk of muscle injury, as well as having serious negative consequences on your metabolism and cardiovascular health.
