Support

Coils

Response Coil

Using an open coil design, the Response Coil layer is comprised of precisely engineered springs that respond to your movement to support you throughout the night. Tossing and turning? A thing of the past.

These encased coils build on the durability and adaptive support of the Response Coil, with increased support, more flexibility for personalized comfort, and reduced motion transfer to help you feel less movement from your partner throughout the night.

Providing more support and reducing motion transfer, this layer of our most durable coils is densely packed and individually wrapped.

Response Pro Zoned HD Coil

Found in our Sealy® Hybrid models, this tightly packed coil system reinforces the center third of the mattress, delivering trusted, targeted support where you need it most – your back and core.

Edges

SolidEdge®

A reinforced foam border around the mattress edge for improved durability.

StableEdge Pro™

A row of sturdy, encased coils helps reinforce the edges of the mattress, giving you more space to sleep and aiding in preventing sagging over time. This system also increases the flexibility of the mattress when paired with an adjustable base.

DuraFlex Coil Edge™

This edge features even more encased coils than our StableEdge Pro™ for improved durability and better flexibility when paired with an adjustable base.

DuraFlex Pro Coil Edge™

This more breathable version of the DuraFlex Coil Edge™ features densely packed coils for added stability and a ventilated design to increase airflow, helping you stay cool and comfortable all night long.
