Why isn’t there a head rest on this chair?
We are considering this feature for the future, but this chair is designed to be effective and comfortable without one! Picture your vertebrae as links in a chain, with each spinal region made of multiple “links”. When one link moves, it affects the others. In biomechanical terms, this is referred to as a kinetic chain. The base of our spinal kinetic chain is the pelvis. If the base is well supported, then the rest of the “links in the chain” have the foundation to be supported as well. This is why it is important to sit back in your seat- to allow the pelvis to be supported in your chair, and provide the foundation for lumbar, thoracic and cervical support. This effectively eliminates the need for a head rest. ALL33 instantly reacts to give you a neutral spine posture and thus eliminates the benefits of a head rest.
