The Complete Sleeprrr Adjustable Memory Pillow is unique to the industry because of its patented design, allowing users to create the thickness that suits their individual needs. This pillow contains removable inserts, enabling the patient to easily build their pillow from 3" to 6" in height, depending on their requirements and preferences. Creative Comfort also offers the Complete Sleeper Plus Pillow for those who prefer a heavier density foam and require an even thicker pillow.
