An adjustable bed (also called a Semi-Fowler bed) can be adjusted to a number of different positions. For individuals with certain types of back problems, sleeping on an adjustable bed that is at a slight incline (e.g. 30 to 45 degrees) may be comfortable, with the upper body positioned higher up than the lower body and some support under the knees to bend the knees at a slight angle. The combination of upper body incline and the knee support can help take some of the stress off the lower back. Provided that the person is comfortable sleeping in this manner through the night, this position can support the curves of the spine and relieve pressure on the entire body. While most popular in hospitals or other medical facilities, adjustable beds are becoming widely used in homes to provide support for sleeping in a variety of positions.
