Spine Offloading Chair

The SPINE Laboratory, Faculty of Medicine, Memorial University of Newfoundland, St. John’s NL.


To determine if there are differences in spine height in response to a 1-hour sitting exposure in a decompression design configuration (a saddle seat pan with chest and arm supports designed to reduce spine loads) compared to a control configuration (saddle seat pan with the chest and arm supports removed) of the same chair.

Secondary objectives of this study aimed to determine whether between chair condition differences exist for perceived back pain, spine posture, seat pressure variables, perceived support/overall comfort, perceived posture, perceived stiffness/tiredness, and perception of the configurations compared to a standard office chair.
