Core Support

Support layers form the core of your sleep set. They provide much of the unsurpassed strength, resilience, and durability of our mattresses and work in conjunction with the comfort layers to help you fall asleep faster and wake up feeling refreshed and pain-free.

Stearns & Foster® offers two types of supportive core systems: Legendary Innerspring and Luxury Latex – which features an innovative latex core.


Legendary Innerspring
The core support of our Legendary Innerspring System is made up of two integral parts: Progressive Support Coils and a foam encasement system.

Innerspring Coils
Our 504 Progressive Support Coils are double offset and crafted of high-carbon steel with a 12¾ gauge – making them 62% stronger and more durable than the coils found in other mattresses. That means stronger and longer-lasting support for the life of your sleep set.

These resilient coils gently cradle your body, sensing your weight and responding with the proportional amount of support. They are also twice tempered to add memory and allow them to reform to your body type and shape as you move.

Encasement Systems
Unlike other mattress encasement systems – which often sacrifice coils to add foam that is glued or pieced together – our UniLock™ Foam Encasement and unparalleled Liquid Injected Foam Encased™ (LIFE) systems are engineered to work with the Progressive Support Coils as a single unit, resulting in superior, long-lasting support.

While the rigidity of both systems provides added sleep surface and a firm seating edge for your mattress, our unique LIFE System™ adds 10% more sleep surface (versus non-foam encased) and an unsurpassed durability to your mattress.

Luxury Latex
By alleviating pressure points and conforming to every contour of your head, neck, and spine, our latex core material can help you achieve a deeper, more restful sleep. You’ll enjoy a unique balance of conformance and support, while avoiding motion transfer and reduced blood flow that can lead to tossing and turning. 

Our patented latex production process produces a seamless, solid core with a consistently supportive feel from side to side. Plus, this innovative material is completely synthetic – making it non-allergenic and anti-microbial. Its pinhole design also provides a natural ventilation system – keeping you cooler in summer, warmer in winter.
