Chirp started with the mission of helping people feel good so they can do more of the things they love. Since then, millions of people have enjoyed the back-popping, knot-kneading relief of the original Chirp Wheel+. The Wheel(s) give people an affordable and relaxing deep tissue massage. Each Wheel features a padded spinal canal to cushion and stretch muscles along the spine while delivering the perfect amount of pressure to relieve different levels of pain and discomfort.
