ABSTRACT:
An adjustable pillow, wherein through-holes 7 are formed at the both ends of a plurality of parallel support bars 6 constituting the head rest. Protrusion adjustment bolts 8 are inserted into these through-holes, and screwed into vertical female thread holes 4, 5 formed in a female thread hole unit section 2, 3 erected on both sides of a base 1. A blocking piece 9 carrying the support bar is attached to the protrusion adjustment bolt 8, at the lower surface of the support bar 6, for blocking the movement in the direction along the axis thereof. A substrate 12 is disposed under the base 1. Height adjustment bolts 14 are inserted into a plurality of through holes 13 formed in the substrate. On the upper side of this substrate, another blocking piece 15 is attached to the height adjustment bolt 14 for blocking its displacement of the substrate in the direction along the axis of the bolt 14 and so as to allow its rotation in respect to the substrate. Female thread holes 13 are formed on said base side for screwing and supporting each height adjustment bolt. Thus, the overall height of a pillow can be adjusted and set to the individual needs.
