Cowchair

The primary question was: is it possible for the chair to follow the rider of the spine? How to modify the structure to make it flexible and firm enough? E.g. the camel throat when traveling through the desert.
Rocking chair combines a variety of ready made elements - (handle, silenblocks), waste - foot, shaft and a unique elastic chair structure. The feeling of sitting is unique. The chair is strong enough to hold sitting together and allows pivoting movement. Unstable area under the thigh muscles stimulates the spinal column.  
Sitting reminds of horseback riding. The user can control the movement by simply changing the center of gravity within the chair's range  of 48 cm in front, 25 cm to sides and 70 degrees to turning. To handle you can attach a Bluetooth interfaces that controls the digital device or place the notebook.
