Which mattress should we choose if we sleep differently?

Do you differ in weight or sleeping position? If the difference is small, you can choose a different firmness for each side of one double mattress, with a maximum of one firmness level difference. If the difference is bigger, two separate mattresses are the best choice: each of you picks your own firmness and materials. Just make sure they are the same height. The Mattress Finder helps you on your way.
