“This slim, one-piece cushion transforms any chair—office, recliner, or spaceship commander seat—into a massage chair. After settling in, sitters can control their massage with a remote control. Two modes deliver quite different styles of touch: air massage gently compresses and squeezes the lumbar area, and shiatsu massage deeply kneads the back. Both options can target the full back or focus on the upper or lower regions. Thanks to the cushion’s slim, portable nature, users can enjoy a massage at the office after a stressful meeting or at home after a stressful episode of Seinfeld.”
