Bonnell Spring vs. Foam

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.

Foam

Mattress foam comes in multiple different types: memory foam, polyurethane, and latex. Memory foam is a type of polyurethane foam that has lower resistance so it reacts and slowly reforms when pressure is released. It generally makes up the surface layers of a mattress.

Polyurethane comes in multiple different forms - making it useful in the middle and base layers of many foam and memory foam mattresses.

Latex is the natural alternative to memory foam and polyurethane foams. It is created from sap from a rubber tree and is treated to create different densities to cover both soft and firm requirements. Like rubber, it is highly responsive and has a bounce that some sleepers love and some others hate.

Pros: Depending on the foam type, it can be quite comfortable, safe, and responsive.

Cons: Lower quality foams can break down quickly, causing sagging issues within only a few months or years.
