US Patent 9756968 Head-neck posture device

A head-neck posture restoration/correction, strengthening device formed from a portable pad having a shape retaining inner core including highly compressed rubber spheres. The inner core top surface has multiple protrusions and is covered by a thin outer shell coating. The shape of the top surface provides a designated neck and head placement area, allowing the user's neck to curve around the designated neck area while translating the weight of the user's head to compress into the semi-resistant designated head area.
