Abstract: A device for treating or preventing lower back pain that is simpler and less costly than previous similar devices. Among the features of the device are a leg rest height adjustment arrangement that is simple to operate and provides substantially continuous height adjustment, a leg rest folding mechanism that pivotally couples the leg rest to a leg rest support shaft to place the leg rest in operative and storage positions, and a flexible cover that does not substantially change its length during height adjustment.
