How do I shop for a mattress?

In recent years visco-elastic memory foam has become cheaper to produce and is now widely available for the home. Its most common domestic applications are mattresses, pillows and mattress toppers (also known as mattress pads). It remains useful in medical-related uses, such as wheelchair seat cushions, and pillows or padding for persons suffering long-term pain or postural problems; for example, a memory foam cervical pillow may alleviate chronic neck pain. Its heat-retaining properties are also helpful to some pain sufferers, who find the added warmth also helps alleviate pain.
