Extra Info

* Pelvic Posture Position:

When we sit into a chair, the weight of the upper body causes the pelvis to roll backwards. Chairs designed using the revolutionary 'Pelvic Posture Principle' take account of this.

Developed by a prominent chiropractor and chartered engineer, they allow the 'wings' of the pelvis to be supported just below the waist and allow the spine to take up its natural shape whilst sitting. The uniquely shaped pelvic support contacts these critical areas of the spine and pelvis, providing increased support.
