Abstract: The present application pertains to dynamic postural systems for improving the postural response in humans through the use of chairs, walkers, crawlers, wearing devices, harnesses, standing devices, wheelchairs, sports and work equipment or other mobility or seating devices that are designed to provide one or more contact surfaces to corresponding one or more postural contact points on the body, which stimulate proper dynamic postures and postural awareness, while allowing unrestrained movement in activity and without the requirements for physical restraint.
