The positioning pillow „Back“ for the spine from Yellow Head is an innovation, which excels with functionality and ergonomics also. The pillow creates a long-lasting mobilization of the thoracic vertebrae and stretches the breast muscles at the same time. It is also suitable for strengthening exercises. This is made possible by the ergonomics of the pillow, which is able to provide strengthening and physical rest at the same time due to its special form and materials. Grips at the side make handling the pillow easier; the removable core allows setting different degrees of hardness for starters or different users.
