Coil Spring vs. High Resilience Foam

Coil Spring

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.

High Resilience Foam

High resilience is a polyurethane foam that has a much higher responsiveness than memory foam, which has a slower response. Because of this, those that enjoy more of a bounce in their mattress will gravitate towards this type of foam.

High resilience foams are much less popular than memory foam, but they make up important layers of many popular mattresses. Oftentimes the transitional layer or base layer of memory foam mattresses will contain high resilience foam at high densities. This provides a more even feel across the mattress, and less of a sinking feeling that memory foam alone would have.

Like all polyurethane foam, high resilience foam is made of a blend of polyurethane and has a tendency to off-gas. If you are susceptible to lung issues, please do additional research on the quality of foams before purchasing.

Pros: Quicker response than memory foam provides many mattresses with an even supportive feel.

Cons: Sagging and off-gassing problems with lower quality foams.
