This pad is specially designed to relax the upper back and dorsal vertebrae muscles. It is the ideal and most comfortable choice for alleviating muscle aches and pains. It is very comfortable thanks to its soft microfibre cover. It offers three levels of heat and takes just five minutes to reach the chosen temperature. It is extremely safe thanks to its automatic-shutoff safety mechanism that is activated after 90 minutes of continuous use. The controller can be removed so you can hand or machine wash it at a temperature of up to 30 ºC (always after removing the controller).
