Bonnell Spring

Bonnell spring mattress systems are the most traditional type of innerspring mattress. The Bonnell coil has an hour glass shape (wider at the bottom and the top than the middle) and are interconnected with a mesh of metal to make the spring system.

In many traditional innerspring mattresses from the 20th century and still some entry level models today have used the Bonnell spring to create durable and supportive mattresses.

Though this system is good at providing even support, there are complaints of aggravated pressure points and discomfort with Bonnel spring systems.

Pros: Durable materials and traditional even feel.

Cons: Pressure point discomfort and motion transfer issues.

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.
