This Convoluted Memory Pillow is a very versatile pillow. Offering three different levels of support to ensure the right fit no matter the sleep style. Sleep with the convoluted, or peaked, side up for medium-firm support (perfect for back sleepers). Position this pillow, if you sleep on your side, with the flat memory foam side up for firm support. Plus, if you are a stomach sleeper, simply remove the memory foam core and sleep on the down alternative fill alone for an ultra-plush feel.
