ABSTRACT:
A pillow with a cover and a filling is described, the pillow having a general rectangular shape and being characterized in that the cover (2) comprises an essentially unstretchable fabric, it has in the empty state, a flat generally rectangular configuration comprising, beginning with a rectangle with a side ratio of about 3:4, a first longer lateral edge containing a centered, inwardly directed curvature (4), while the other longer lateral edge has a centered, outwardly directed curvature (5); the filling (3) consists of essentially spherical fiber aggregates formed by spherically intertwined fibers and/or filaments, and the fiber aggregates filled into the cover (2) have a pile density amounting to 3 to 7 times the apparent density of the fiber aggregates in the uncompressed state outside the cover (2).
The pillow of this configuration may be produced in a simple manner, is readily adapted to the needs of the user and adequately supports the head of the user both in the supine and the lateral position.
