Using your Shoulder Zoned Gel Dough® Pillow is easy. Just place it on your bed and rest your head on it. Make sure your head is centered in the shoulder recess for side sleepers to get the best support and pressure relief. For maintenance, you can spot - clean the Tencel® cover with a mild detergent and water. Avoid machine - washing the cover as it may damage the fabric. Keep the pillow away from direct sunlight and high humidity to maintain the quality of the bamboo charcoal and memory foam. If you notice any issues with the pillow, contact our customer service as it's backed by a 5 - year warranty.
