This lightweight cushion is designed to relieve pain and tension. The massager cushion uses the weight of your head to create a natural traction stretch for your neck and back while two nodules stimulate pressure points on your neck. This increases blood flow, relaxes muscles and releases tension in your neck and shoulders. - mysmartbuy Neck & Shoulder Massage Cushion - Durable High-Density Memory Foam Pressure Point Massaging Tool - 24 x 21 x 13cm - Size: 24 x 21 x 13 cm
