Conforming heating pad

A heating pad comprising:

• a first layer on a posterior side of the heating pad;
• a second layer having a conductive heating element distributed throughout the second layer, wherein the conductive heating element is selectively heated to increase the temperature of the heating pad;
• a third layer having a posterior layer, an anterior layer, and a plurality of beads, wherein the posterior layer and the anterior layer include dimples formed therein and spaces between the dimples, with respective dimples and respective spaces of the posterior portion and the anterior portion being aligned, wherein alignment of the respective dimples form a plurality of cavities configured to hold the plurality of beads, and wherein each cavity of the plurality of cavities holds a respective bead of the plurality of beads, such that the beads, and thus the weight of the beads, are evenly distributed throughout the third layer, wherein the plurality of cavities are arranged in a grid pattern with a plurality of columns and a plurality of rows, and wherein each of the plurality of cavities are separated from one another by the aligned respective spaces;
• and
• a fourth layer on an anterior side of the heating pad;
• and
• wherein when the heating pad is applied to a body portion of a user, the weight of the beads applies a force against the conductive heating element, the second layer, and the first layer to thereby conform them to a body portion of a user of the heating pad;
• and
• wherein, when the heating pad is assembled, a portion of each of the plurality of cavities is at least partially positioned over and on top of the heating element.
