Is there a clothing size that everyone should wear? Absolutely not. A teen, for example, may require a twin bed or a queen. If you are overweight or if you are married, you may require a different size of mattress than "the norm." And even though queen-size mattresses are the most popular at the moment, a queen may not suit all your needs.

According to the International Sleep Products Association, in 1998 sales of queen-size mattresses made up 31.6 percent of all mattresses sold. For the first time, queen-size mattresses outsold twin-size (29.8 percent), which dropped ten points in market share from 1997. Full-size mattresses slightly decreased in market share, while king-size increased slightly.
