Double Core Select Pillow Features:

With new, easily interchangeable, color-coded cores, the Double Core Select is the most versatile foam pillow on the market. As you become accustomed to each lobe you will crave a firmer support. Start with the white core, the softest and most accommodating, and gradually work your way up to the gold core, the firmest and most supportive. Easily choose the level of support you need without changing pillows. Fits a standard pillowcase. Washable cotton/polyester cover included.
