Abstract: A foam mattress includes a reticulated, viscoelastic foam that makes up the mattress in whole or in part. The reticulated nature of the viscoelastic foam allows a user to enjoy the benefits of softness and conformability of a viscoelastic foam and also an improved breathability. The foam mattress may include a plurality of zones of foam and/or a plurality of layers of foam, where one of the layers may be reticulated urethane for improved breathability and humidity resistance, as well as heat dissipation.
