The Midnight is our best bed in the luxury collection. The bed is made with two Gel Matrix layers to give you even more dynamic responsiveness. Even Firmer. Even Softer. And supported with a high count, tempered and wrapped coil system to provide great motion control. This mattress features copper-infused latex, which provides superior comfort and exceptional support. Additionally, the copper-infused latex is naturally cooler than memory foam, and is resistant to bacteria growth. The Quantum EdgeTM provides the best motion control and a consistent feel throughout the entire mattress.
