Abstract: A reversible or hybrid mattress topper includes a first foam plate having a first density, a second foam plate having a second density different than the first density of the first foam plate, and a spring panel that is disposed between the first foam plate and the second foam plate. The spring panel includes a plurality of coil springs positioned between an upper fabric layer and a lower fabric layer, with the upper and lower fabric layers joined together. An insulating layer extends along an outside surface of each of the first foam plate and the second foam plate.
