Keep your pillow in place while in an adjustable bed.
“When my grandson uses his hospital bed, his pillow can slip down too far or out of place when he raises and lowers his head. To fix this, I placed a 1/2″ piece of PVC pipe inside of his pillow case at the top. I then attached two spring clips using elastic cord. The spring clips clamp over the pipe inside the pillow case and the other end is tied to the bed frame at the desired length. The elastic cord allows some degree of adjustment. This has worked well for several years.”
