A system can include a base configured to support a lower half of a human body. The system can also include a headrest elevated relative to the base, wherein the headrest is disposed adjacent to a proximal end of the base, where the headrest is configured to support a head of the human body. The system can further include a back platform having a first end and a second end, where the first end is coupled to the base, where the second end is disposed adjacent to the headrest, and where the back platform has a curvature, where the back platform is configured to support a torso of the human body. The system can also include a vibrating mechanism in communication with the back platform, where vibrations generated by the vibrating mechanism translate to the back platform.
