Copper, Charcoal or Graphite Infusion Serta® iComfort® All
These mattresses blend copper, charcoal, graphite or similar minerals into their foam layers or cover fabric. These materials conduct heat well, helping move warmth away from your body, and are also used to help keep the mattress fresh by resisting odour. A good place to start if you sleep warm and want cooling built into the materials themselves.
