Tempur Millennium Pillow Queen Medium is an ergonomic pillow in a firm feel developed for back sleepers who want to relieve neck discomfort. A curved edge and centered notch that precisely encloses and supports your head and neck helps provide correct alignment. While this limits the movement of the person sleeping, it allows tensed and strained muscles to recover. Tempur Millennium Pillow provides targeted support for back and side sleepers. The front edge of this pillow tilts slightly forward and helps provide correct neck alignment. With a notch specially designed to cradle your head and neck and a curved ridge to comfort your shoulders, you'll experience uncompromising support and comfort all night long. Now with new SmartCool Technology™ which absorbs excess heat throughout the night, you'll wake up feeling even more refreshed. While your pillow gently cradles your head, neck, and shoulders as you lie down, each cooling thread naturally disperses heat away, to help keep you cool and comfortable all night long. It is made with the same unique TEMPUR® Material found in their mattresses, Tempur pillows provide complete support all night long. Visco-elastic cells that actively mould and adapt to your head, neck and shoulders. This pillow has a washable cover. It can be washed at up to 60°C to kill all dust mites, so you can always enjoy a fresh and clean pillow.
