The Serta Artic Hybrid Medium Mattress contains a three part Reactex System which is engineered with 15X better cooling power. Each layer has more cooling capacity than the previous layer, so heat is pulled away from your body and down into the mattress. The result is cool, comfortable sleep all night long.
