Before you even start researching mattresses, you need to have a checklist in mind. If your are a first-time mattress buyer, make a list of your "sleep needs." Do you need extra comfort? Extra space? Are you part of a couple? If you are purchasing a new mattress, think about the changes in your life since you last bought one. Have you married or have you lost a partner? Have you suffered an injury or developed a sleep disorder? Have you aged? Remember, as you age your mattress needs change. If you are buying a mattress for a child, your child has special needs too (see question on "What kind of mattress do children need?"). If you are married, involve your spouse in the buying decisions.

Also, remember CSSM - Comfort, Support, Space, and Matched Set. Let's face it, you buy a mattress because it feels good. Secondly, you buy it because it holds your spine in place and keeps you from waking up feeling stiff and sore. You also want a mattress that doesn't make you sleep in a cramped position, particularly if you live with a partner. Generally speaking, couples sleep best on a queen or king-size mattress. And what you may not know is that you want to purchase a mattress and foundation together. See "Perfect Match."
