Power beds, otherwise known as adjustable beds, add another dimension to your bedroom environment and sleeping comfort. One obvious benefit is the ability to sit up in bed to read, eat, or watch television, however adjustable beds also help improve sleep. The ability to elevate your legs relieves back pressure, as well as improves circulation. Allowing your body to rest in a contour, or "fetal" position, the adjustable bed reduces the need to sleep on your side, eliminating the added pressure that comes with side-sleeping. Certain physical conditions can also be alleviated with adjustable beds.
