Memory foam mattresses are becoming very popular, but you need to know what is out there before you buy one. Some of the mattresses are made with different material, and there are some that are much more expensive than an ordinary memory foam mattress. Don't buy the first one that you come across. Sit on the mattress and even lie on it to make sure it is the right fit for you. If you have a bad back, then a memory foam mattress may not be right for you.
