Why use massage pillows? Looking after your body after a long day at the office or when travelling is very important, we often neglect and take for granted the way that the body copes with stress and tension. The soft pillow portable back massager is a handy and effective way of dealing with muscle strain and posture issues. It helps to ease pain by releasing heat in soothing waves. Again, a massage pillow is NOT an adequate replacement for professional massage therapy,  but rather an additional way to seek relief at home. If you are currently undergoing treatment for a medical condition, it is best to discuss whether or not you should use a massage pillow. If you have suffered an injury or endured trauma to an area of soft tissue,  we may recommend against purchasing one. Who will benefit from massage pillows? Anyone who suffers from knots, tight/stiff muscles, muscle spasms, and neck tension headaches will find these relatively low-cost pillows to be their new best friend and will save them a lot of money on chiropractor/masseuse visits.
