1951 Pillow for Prone Posture Sleeping, C.M. O’Brian U.S. patent no. 2,556,629
Less of a pillow that cushions or bolsters a part of the body, this piece, when suspended, casts a series of ever-changing shadows and can be used to promote a state of contemplation leading to sleep. In this capacity, it falls into the extensive patent category of sleep-aids.
