The Sharper image air and shiatsu massage cushion gives an air massage that compresses and gently squeezes your sides and lumbar area. Adjust the air intensity to low, medium, or high and massage your lower, upper, or entire back for the exact massage you need. Two Shiatsu nodes travel up and down your back for a deep kneading massage. Choose the optional soothing heat to enhance your massage experience. The corded remote gives you complete control over your massage experience.
