As a violinist with severe neck issues threatening my career, my performance medicine specialist recommended CozyRest after multiple approaches failed. By week three, I noticed decreased stiffness, particularly on my violin side. After six weeks, I could practice for extended periods without the progressive pain that previously limited rehearsal time. After three months, my asymmetrical tension patterns improved substantially, and I regained performance endurance I thought permanently lost. The cooling technology works as advertised. While pricier than standard pillows, compared to the career implications of limited performance capabilities, CozyRest has provided exceptional value while saving my musical career.
