Abstract: A comfort system for use with a mattress comprises: a base layer configured for placement below the mattress, including a central portion that is configured to extend from a first side of the mattress to a second side, with one or more appendages extending from the central portion; and a top layer configured for placement over an upper surface of the mattress, including a central portion that is configured to extend from the first side of the mattress to the second side, with one or more appendages extending from the central portion. Each of the appendages of the top layer includes a closure means that is adapted to engage a corresponding closure means on one of the appendages of the base layer. The comfort system can be moved along the length of the mattress, and the material of the top layer can be selected for a particular malady or use.
