What is the difference between a box spring and a foundation?
A foundation is a wooden frame that looks like a box spring but is made from untreated wood. A box spring has springs in it. Typically, foundations provide a firmer support surface for your mattress. Most people purchase foundations with their natural latex mattress but they can also be placed on a boxspring. This is a personal preference. Consumers who are concerned about electromagnetic fields prefer foundations with no metal in them.
