One of the most cooling Serta iComfort® models, this medium firm memory foam mattress offers highly refreshing comfort and support. Both cool-to-the-touch and breathable, the Max Cold™ cover, coupled with the UltraCold™ system, instantly absorbs and dissipates body heat away from the soft and consistent cover. Designed with a minimal barrier between the quilt and comfort layers, you'll entirely experience the carbon-infused memory foam lending additional strength and organic temperature regulation. To achieve a firmer and more supportive sleep surface, double layers of Deep Reaction™ max memory foam and the Serta® foam core relieve neck and back pains with resilient ease.
