This unique Sleep Innovations 2-in-1 Reversible Memory Foam Pillow has a layer of memory foam and a layer of fiberfill, giving each side a distinct feel and giving you two ways to sleep. The plush, down-like fiberfill offers the feel of a traditional pillow, while the layer of memory foam on the opposite side offers the firm support and therapeutic benefits of memory foam. Both sides add up to a more restful, restorative sleep and a more rejuvenating tomorrow.
