Using this pillow is easy. Just place it on your bed and rest your head on it as you sleep on your side. The unique shoulder recess will support your neck and head comfortably. When the lavender scent starts to fade, use the included 2 ml spritzer to refresh it. For maintenance, spot clean the Tencel® cover if it gets dirty. Keep the pillow away from direct sunlight and high heat to preserve the memory foam's quality. Also, make sure to follow the general guidelines on the CertiPUR - US certification. This pillow is backed by a 5 - year warranty, so if you have any issues, reach out to our customer service.
