What pillow types are best for neck pain?
In side-sleeping patients without chronic neck pain, standard shaped rubber pillows reduce the incidence of morning neck pain while feather pillows increase pain, compared with patients’ usual pillows. For patients with chronic neck pain without nerve impingement, waterbased pillows are superior to roll-shaped pillows and standard (down or foam) pillows in diminishing pain severity upon waking (SOR: B, small RCTs).
