Abstract: An inflatable mat includes a compressible inner mat and an airtight shell. One or more heating elements are embedded within the compressible inner mat. Embedding the heating elements within the mat includes removing sections of the inner mat, splitting the sections into upper and lower pieces, inserting the heating elements between the pieces, replacing the section and heating elements to the inner mat, and bonding the airtight shell to the inner mat. Wires embedded in the inner mat conduct electricity from an external power source to the heating elements. The wires may extend primarily around the edges of the inner mat and penetrate into the inner portions of the mat proximate the heating elements. A thermostatic switch and a timer may be interposed between the heating elements and the external power source to control current passing through the heating elements.
