Expanable Pillow System

Abstract

The expandable pillow system has a top-end head pillow and two side pillows interconnected by elastic fabric which fabric adjustably vertically spaces apart the head from the sides and adjustably horizontally spaces apart the sides causing the left-right sides to adjust adjacent either the user's back or side, thereby forming vertical arm channels and a horizontal body channel. System sold with or without insertable pillows and also operable with 1,2 hemispherical side pillows. Enhancements include side pillow cases with closable seams converting interior pillow cases a substantially cylindrical interior space to a substantially hemispherical interior space.

 the elastic fabric is attached to the head pillow case and the left-side and right-side pillow cases. 
 
     
     
         8 . The expandable pillow system as claimed in  claim 7  wherein the head pillow case and the left-side and right-side pillow cases and the interconnecting elastic fabric form a unitary structure and the head pillow and the left-side and right-side pillows are distinct, independent components insertable into respective cases. 
     
     
         9 . The expandable pillow system as claimed in  claim 1  including a head pillow case and a left-side pillow case and a right-side pillow case, the elastic fabric is attached to the head pillow case and the left-side and right-side pillow cases. 
     
     
         10 . The expandable pillow system as claimed in  claim 9  wherein the head pillow and the left-side and right-side pillows are removably insertable into the head pillow case and the left-side and right-side pillow cases. 
     
     
         11 . The expandable pillow system as claimed in  claim 10  wherein the head pillow case and the left-side and right-side pillow cases and the interconnecting elastic fabric form a unitary structure and the head pillow and the left-side and right-side pillows are distinct, independent components insertable into respective cases. 
     
     
         12 . An expandable pillow system for a user resting on a bed or other resting platform and used in connection with three pillows comprising:
 a head pillow case and two side pillow cases interconnected by elastic fabric;   the head pillow case attached to the top edge of the fabric and the two side pillow cases attached to opposing sides of the fabric as a left-side vertical pillow case and a right-side vertical pillow case;   the head pillow case adapted to retain therein a first pillow of the three pillows;   the corresponding left-side case and right-side case respectively adapted to retain a second and a third of the three pillows therein;   such that, in a first deployed position, the head pillow is vertically spaced apart from the left-side and right-side pillows with the left-side and right-side pillows being horizontally spaced apart from each other, and, in a body-use position, the head pillow is adapted to vertically adjust to a user's neck and either one or the other of the left-side pillow and the right-side pillow is the adapted to horizontally adjust to either a user's back or a user's side.
