Get seriously comfortable with this versatile pillow. Memory foam is soft and bouncy, retaining its shape for life. Memory foam softens with your body heat, moulding to fit the shape of your head and neck, and reforms to its original shape when it cools. This cradling effect keeps your spine where it should be and allows your neck muscles to relax, giving you a restful sleep. V shaped pillows are loved for their versatility - they are great for sitting up in bed or doubling as body pillows, and their unique shape provides shoulder support. This product is also hypoallergenic, as memory foam is a poor environment for dust mites and bacteria. Note: This Pillow will fit in the Logan and Mason Tri Pillowcases.
