Talalay Latex
Latex is one of the longest wearing components available in a mattress. Its push back, resilient nature makes it a perfect material for a comfortable mattress. The Talalay process of producing Latex provides a softer Latex with more air.
Independent Coil System
Each Pocketed Coil is Individually Wrapped, allowing them to adjust to your body for a more customized support. You'll also experience reduced motion disbursement, so you won't wake up every time your partner moves.
Micro Coils
A layer of mini, Individually Wrapped Coils providing additional cushioning and support as an additional comfort layer.
Foam Encasement Perimeter Foam Block
This Edge Support creates a sturdy edge that responds along with the coils, allowing you to sleep comfortable all the way to the edge.
