A support material having an hourglass shape reduces the cost of manufacturing as well as increasing comfort and air circulation. The support material includes a primary end having a primary diameter located opposite a secondary end having a secondary diameter. A substantially central portion of the support material has a tertiary diameter being a size less than the primary and secondary diameters. Additional improvements include an improved outer wall surface of the support material having at least one recess. The at least one recess can retain a substance such as a cooling gel.
