Sweet deal, just ordered 1 of these to use before bed for stress relief, relaxation and better sleep. Sometimes it becomes difficult to fall asleep until 3 am I hope this mat helps. My uncle has one at home that helps relieve his back pain and told me the mat is great for releasing tension, stress, stiff muscles and relaxing your body. Thank god I don't have back pain but having a 60 hour work week adds stress and tension. Let's hope this helps.
