The SONO Pillow combines thoughtful ergonomics, engineering, and aesthetics into one of the latest travel must haves. Support meets style in this modern travel pillow with its custom designed side bolsters, thin neck band, and a flexible spine. The inward curve, the rounded shoulders, and the gentle rise combine to tilt your head gently back towards its natural resting state. A state that opens the airways to promote better, healthier breathing. The side bolsters conform to your collar bone rising all the way to the chin to reduce lateral flexion. So your neck won’t get sores from falling too far to the side. The flexible spine will allow you to contort the pillow into whatever position you prefer. To maintain ergonomic integrity, it was crucial the pillow be rigid enough to hold its shape. After much trial and error, the team discovered the perfect blended memory foam combined with an internal spine that allows the SONO Pillow to stay in place no matter how you like to sleep. It conforms to your shoulders and neck maintaining its form while being soft enough to ensure a good nights sleep.
