A random-allocation block-design blinded field trial was conducted in a large South Australian regional town. Subjects were side-sleepers using one pillow only, and not receiving treatment for cervicothoracic problems. Waking cervical stiffness, headache and scapular/arm pain were recorded daily. Five experimental pillows (polyester, foam regular, foam contour, feather, and latex) were each trialed for a week. Subjects’ ‘own’ pillow was the control (a baseline week, and a washout week between each experimental pillow trial week). Subjects reported waking symptoms related to known factors (other than the pillow), and subjects could ‘drop out’ of any trial pillow week.
