      A small number of studies have taken place at a number of universities with encouraging results. Please note due to the nature of this type of research the results have to be considered cautiously and would really need to be repeated in much larger studies blinded randomised controlled studies to have a high level of confidence in the results

      A University of Waterloo study indicated that the Corechair can deliver sitting posture and pelvic activation benefits akin to and even superior to an optimally adjusted exercise ball.A study at the University of Guelph demonstrated enhanced circulation in Corechair users. Finally, a Cornell University study reported greater user comfort in core chair users when compared with other ergonomic chairs in the study.
