Bedding or Seating Product Having Topper With At Least One Thermally Enhanced Foam Component

A three-layered topper for a bedding or seating product has a first piece of foam, a second piece of foam and a pocketed spring comfort layer therebetween. The pocketed spring comfort layer has individually pocketed mini coil springs. At least one of the foam pieces may be infused with metallic particles to improve thermal conductivity. Alternatively, at least one of the foam pieces may be infused with microencapsulated phase change materials to improve heat absorption. At least one of the foam pieces may have a coating to further improve thermal conductivity or heat absorption.
