Original designs of uniquely shaped pillows by a chiropractor & a sleep industry designer. Better than any other pillows you've seen. Good sleep and Yoga are both beneficial to the body. Yoga helps strengthens our core muscles and keeps our body flexible, which, in turn, improves our posture; not only does this delay the effects of time and prevent stiffness and pain, it also allows us to breathe more freely. This increased oxygen flow improves our general health and allows us to feel more alive and rested.Our Sleep Yoga™ Posture pillows were designed to provide these very same benefits by comfortably improving your posture while you sleep.
