Wondering how to choose a mattress? To get a good night’s sleep, choosing between a firm queen mattress and twin pillow top mattress should be more about size than softness. White noise, furniture placement, and dimmed lights are all factors that can affect proper rest, but studies and doctors agree that the most important factor is a correctly-sized mattress.

Even though sheet sizes and headboards limit the length of any mattress, even a person of an average height (just under six feet) is best served with a mattress six and a half feet long. For someone taller, an extended (and in some cases, specially-made) bed is recommended. Bent legs and trapped feet keep the body in a state of perpetual tension, which inhibits the body from achieving as pure and deep a sleep as needed for fulfilling rest. Although the national height average has increased over the last few decades, twin beds remain a staple size, which are simply too small for many adults.
For couples, size is especially important. Even if you or your spouse do not tend to move or thrash much in your sleep, space is necessary for a restful, fulfilling sleep. Double beds may be a more economic choice, but when shared by two people, they constrict as much movement as a crib does for a toddler. Even simply turning over is severely restricted on such a bed, so a firm queen mattress or king mattress is a better investment—for personal rest and to remain compatible sleeping partners. A larger mattress will certainly cost a bit more, but because a mattress’s inherent purpose is to promote healthful sleep patterns, the higher price is a worthwhile one.
