One of the largest growing segments in the mattress industry is the adjustable bed. Sometimes referred to a hospital bed, these units sit under the mattress and allow for different sleeping or resting positions. They generally have one or more hinge points that can offer various positions for sleep, reading, watching tv, or breakfast in bed. Some models only allow the upper portion to be raised to offer a more upright resting position and others have a lower level adjustment option as well. These can be used independently of each other to offer several positions.
Today they are heavily marketed as a lifestyle choice and can offer massage, lighting, device charging using remote control functionality. Price among models varies greatly from a few hundred dollars to thousands depending on style features and quality.
