This firm mattress gets both its support and firmness from a 711 Firm Foam Encased Wrapped Coil System, featuring durable, flexible wrapped coils that react individually to every contour of your body. It also contains a Gentle Support™ Aire towards the surface of the mattress, an ultra-soft layer of foam that provides enhanced cushioning and promotes airflow to help reduce heat build-up. Plus, a layer of gel-infused Gel Active™ Foam gently cradles your body and helps dissipate heat throughout the night.The Glastonbury Firm is compatible with all adjustable foundations.
This mattress is compatible with an Active Base (sold separately). Whether you are purchasing your adjustable bed base for health reasons, to read, write, watch TV more comfortably, or simply to get a better night's sleep, this mattress is designed to support your active lifestyle.
Hundreds of individually wrapped coils work independently to conform to the body, responding to pressure and providing extra support where you need it most.
A border of high-density foam encases the innerspring system to provide additional edge support. This expands the sleeping surface all the way to the edge and helps prevent sagging and rolling off the sides of the mattress.
