Therapeutic pillow

A therapeutic pillow for placing on a seat and for being sat upon by a user, wherein the user has buttocks and a tail bone with a somewhat circular periphery, and for supporting the tail bone of the user and for cradling the buttocks of the user to assure that support for the tail bone of the user is held in place, said pillow comprising:

• a) a base for overlying the seat;
• said base being thin and generally rectangular-parallelepiped-shaped and having a lower face for overlying the seat and an upper face disposed above said lower face of said base for sitting upon by the user;
• said lower face of said base having a pair of axial edges and said upper face of said base having a pair of axial edges and an axial centerline;
• b) a support disposed axially along said base for supporting the tail bone of the user;
• said support being narrow and having a lower face extending along said centerline of said upper face of said base;
• said lower face of said support having a pair of axial edges and a pair of lateral edges;
• said support further having a pair of axial side walls extending vertically upwardly from said pair of axial edges of said lower face of said support, respectively;
• said support further having a pair of lateral end walls extending vertically upwardly from said pair of lateral edges of said lower face of said support, respectively, and meeting said pair of axial side walls of said support, respectively;
• said support further having a top wall extending generally horizontally from one axial side wall of said pair of axial side walls of said support to the other axial side wall of said pair of axial side walls of said support and from one lateral end wall of said pair of lateral end walls of said support to the other lateral end wall of said pair of lateral end walls of said support and having an axial profile extending from said one lateral end wall of said pair of lateral end walls of said support to said other lateral end wall of said pair of lateral end walls of said support, a lateral profile extending from said one axial side wall of said pair of axial side walls of said support to said other axial side wall of said pair of axial side walls of said support, and an entire length;
• said axial profile of said top wall of said support being straight along said entire length of said top wall of said support while said lateral profile of said top wall of said support being concave along said entire length of said top wall of said support relative to said pair of axial side walls of said support and said base when having a viewing position being right side up with said base being positioned below said top wall of said support for substantially matching the somewhat circular periphery of the tail bone of the user so as to provide maximum support for the tail bone of the user without discomfort;
• and
• c) a pair of bolsters extending axially along said base, straddling said support, for cradling the buttocks of the user therebetween so as to assure that said support is held in place under the tail bone of the user by minimizing lateral movement of the user.
