What is a Coil Spring Mattress?

Coil spring (also called innerspring) mattresses use metal coils to provide resistance and support. Contemporary bedding use pocket coil systems that are entirely independent from each other so there are less pressure points. The rule of these new pocket coil systems is the more coils that are used, the more independent movement and response is in mattress.

Older coil spring mattresses, however, have one frame with coils interconnected to one another. Although this provides good support across the entire surface, and a longer durability life, there are comfort concerns about these mattresses.

Additionally, most coil spring mattresses have memory foam, latex, or some other type of bedding to provide a soft surface to sleep on.

Pros: Durable materials, and newer pocket coil systems provide comfortable support.

Cons: Older coil spring mattresses can cause more back pain and irritate pressure points.

Additional Coil Spring Facts

How It's Made

Coil spring systems are created by tempering hot metal into coil springs. For older mattresses, they are then interconnected and added below the top layer of comfort material. For newer models, the coils are individually wrapped in a cotton or polyester sheath and stitched in to the mattress.

How it is Used in Bedding

The coil springs make up the foundational support area of the mattress. Softer materials are placed on top to provide cushioning in the mattress.
