Abstract
A chair having two body supports which move in similar rotation and inverse elevation to one another to change from a chair configuration, where one support is higher than the other, to a spine tensioning apparatus, where the supports are near equal in elevation. Preferably body supports are spaced apart from one another such that the only interconnecting human link between the two supports, when in a near equal elevation configuration, is the human spine. The spine, in this configuration is then subjected to similar forces as a simple beam supported by two separate forces, tension, compression, shear and moment. The spine is aided by and through tension and contraction and increased blood flow and afforded the ability for spinal muscle, nerve and soft tissue development and maintenance. The supports, independent of each other, comprise an upper body support and a lower body support and allow an individual's body to practice spine enhancement, development, & or traction, laying or any combination of, or alternately, face up, face down, or on either left or right side. The apparatus is also be applicable to retrofitting existing chairs.
