Beware of Imitations

The Evolution Chair™ is the original ball chair designed ten years ago by Dr. William Liebenberg. There have been a number of cheaper imitations over the last few years but we have maintained the high quality that earned the Canadian Physiotherapy seal of approval.


  • No toxic off-gas vinyl compounds and plasticizers in our balls.
  • No epoxy and styrene copolymers in our base.
  • Our anti-bacterial Cozys are breathable and odor resistant.


The two key design features that set the Evolution Chair™ apart from other ball chairs are the absence of a backrest and the ability to adjust the height of your Evolution Chair™.

  • Backrest: Backrests defeat the purpose of strengthening your core as they encourage a postural slump.
  • Height adjustability: It is vital to sit in the correct position for perfect spinal alignment with your hips slightly higher than your legs.
    The Evolution Chair™ can be adjusted to fit anyone as every chair includes height inserts to accommodate people over 5'8" tall.
