This massage cushion is specifically designed to relieve stiff shoulders by loosening the shoulder blades. It doesn't require electricity, so you can take it anywhere. Just lie down on it for 10 minutes a day, and you can simultaneously relieve shoulder stiffness, stimulate pressure points, and stretch your back. By adding a swaying motion from side to side, your body weight is firmly applied to your back, gently and thoroughly loosening the stiffness. The pillow is neither too hard nor too soft, with a comfortable texture that feels smooth against the skin. Each individual protrusion fits firmly into the pressure points, and the wide range of coverage allows for a single session of acupressure and stretching for the entire back, saving time on massage. As you sway while taking deep breaths, you'll feel so relaxed that you might even fall asleep. You'll feel refreshed all over after the massage. I bought two and use one every day. I am selling the unused one. I have opened it once to check the contents thoroughly. There is no original box. It will be shipped via anonymous delivery with a full refund guarantee, using Mercari shipping.
