Mattress preferences are exactly that — not what's "best," but what you prefer. The first concern on most people's minds when they're thinking of buying a new mattress is comfort — how soft or firm the mattress feels. Beyond that, there are lots of other variations and features that you can choose in your mattress, depending on what is important to you. Determining what your preferences are will help you narrow your search for the right mattress.
"Comfort" is the way the surface of the mattress feels against the surface of your body. It is what makes you feel cozy and relaxed in your bed, and it is probably the first thing you notice when you lie down. Mattress companies typically use words like "firm," "plush," and "pillow-top" to describe the comfort attributes of a bed, though what they are really getting at is whether the top layers of the mattress (what you feel when you press the mattress surface with your fingertips) feel "soft" or "hard." Other comfort-related attributes include features that minimize disturbance from your partner's movements, or that provide for differing levels of comfort on each side of the bed. More than any other aspect of your bed purchase, judging a mattress' comfort will be a matter of personal preference.
In addition to comfort-level, you can consider a wide range of other options that today's mattresses offer. You may want to consider mattresses made with chemical free or organic materials. You may be considering an adjustable bed base. We'll tell you what's possible so that you can choose a mattress that has the attributes you want.
