Select the support thats right. With new, easily interchangeable, color-coded cores, the Double Core Select is the most versatile foam pillow on the market. Start with the white core, the softest and most accommodating (previously not available in the Double Core line), and gradually work up to the gold core, the firmest and most supportive. Easily choose the level of support needed without changing pillows. Fits a standard pillowcase. Washable cotton/polyester cover included. 22 x 16 (56cm x 41cm) with 4 (10cm) lobes
