This is a great idea. On a related note I just read this ~2000s article[0] by an anthropologist about natural sleeping/resting positions amongst humans/primates. An interesting take he had was that having the chest firmly on the ground during sleep was ideal because breathing causes constant motion of your spine and prevents stiffness.

Interesting, that fit's one of the lines of research on disc health because the disc are nourished indirectly mostly through the porous vertebrae, it takes motion to create the pressure variations to facilitate blood flow. This may be why most active chairs don't move the needle enough, the motion is both limited and usually only triggered when a person is prompted to move by discomfort.
