摘要

The pillow, measuring only 28 x 15 x 10 cm, is made from a specially adapted foam and has a half-moon concave recess in its upper surface. It is covered by an elasticized pillow case to avoid creases and held in a rectangular U-shaped frame with internal anchoring elements, fixed to the mattress of a bed. The resilience of the pillow's foam can be modified to suit particular needs, and it can be made in various sizes.
