A spring mattress uses a coil system as its main support core. Common constructions include interconnected spring systems and individual pocket springs. In an individual pocket-spring mattress, each coil is wrapped separately so it can respond more independently to pressure, helping the mattress contour to the body and reduce motion transfer between sleepers.
The firmest mattress in our collection, the Essence Firm Mattress™ is designed for sleepers seeking an extra firm mattress to provide orthopedic support and ideal weight distribution.
