The Pillow itself was too thin to sleep on alone. Tried 2 pillows together but it was too stiff, so I customized it. Take a zippered Pillow Protector and slip the Foam pillow into it. Now find a worn, thin Polyfilled King size pillow. If you need to, cut open a Polyfilled King pillow and remove some of the filling to make it thinner and stich the opening. Work the thin Polyfilled pillow into the Pillow Protector with the Foam Pillow and zip up the Liner. Now add an pillow case and you have a custom Foam/Polyfill Pillow. This worked well for me, gave me the added height needed to sleep on the pillow and additional softness of the Polyfill and comfort of the Foam. Perfect.
