Back supporting apparatus, chair and method of using the same

A chair having at least a backrest, the chair comprising:

• a plurality of variable spine support elements coupled to the backrest and spaced apart from one another to define a spine receiver to stabilize the user's spine, the spine support elements comprising:
• a first spherical transverse protrusion;
• and
• a second spherical transverse protrusion spaced apart from the first spherical transverse protrusion plane by a valley, the valley being configured to receive any one of a neck vertebra, a thoracic spine, or a lumbar spine;
• wherein the plurality of variable spine support elements are dimensioned with varying thickness on their transverse plane to correspond with the user's lordotic curve.

A method for supporting the spine of seated user, the method comprising:

• attaching an elongated base to a backrest of a chair, the elongated base being positioned in a sagittal plane;
• wherein the elongated base comprises a plurality of variable spine support elements coupled to the base and spaced apart from one another to define a spine receiver to stabilize the user's spine, the spine support elements comprising:
• a first spherical transverse protrusion;
• and
• a second spherical transverse protrusion spaced apart on its coronal plane by a valley, the valley being configured to receive any one of a neck vertebra, a thoracic spine, or a lumbar spine;
• wherein the plurality of variable spine support elements are dimensioned with varying thickness on their transverse plane to correspond with the user's lordotic curve.
