Don’t slouch!

In it’s natural position the spine is slightly « S » shaped, which allows it to balance the upper body efficiently and with minimal effort. It is essential to maintain this natural « S » shape when sitting to avoid excessive loading on the vertebrae that can cause pain and fatigue in the back and tension in the shoulders.


Always avoid sitting in a slouched position (as shown in the picture) because the loads on the vertebrae and muscles in the back will be dramatically increased.






Always use a firm support for the back and recline backwards maintaining a natural « S » shape whenever you can. This will protect your back, shoulders and neck from fatigue and pain.





Recline backwards – it’s the healthiest position!

Medical studies show that reclining backwards at an angle between 110-130 degrees is the most relaxing position for the back.

Studies made bay NASA have also shown tah in zero gravity conditions the body naturally adopts the position of least stress at an inclination of approx. 125 degrees between the upperbody and the legs. Spina-Bac will easely convert your chair to this natural « haelthy » position.
