Using the ComfortSoul Full Circular Bolster Pillow is easy. Simply place it under your knees while lying down to relieve pressure and enhance comfort. When not in use, store it in a dry and clean place. To keep it in good condition, you can spot - clean the DuraSoft™ upholstery with a mild detergent. Avoid using harsh chemicals or machine - washing as this may damage the pillow's padding and cover.
