Specialty pillows require specialty pillowcases. If you own a contour, memory foam, or Tempur-Pedic pillow, you must get a pillowcase that will match its unique shape without taking away any of the comfort. Relax The Back offers comfortable 100% cotton pillowcases in a variety of different sizes. Our Relax The Back pillowcases are perfect for memory foam pillows, Tempur-Pedic pillows, and special contour pillows as well.
