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.

Open Coil

Open coil mattresses are also called traditional innerspring mattresses. They have interconnected coils in a metal mesh that provide even support across the mattress surface.

Many open coil systems use hour glass shaped springs in their interconnected systems so that the evenness is distributed from the top to bottom.

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

Pros: Durable materials and traditional even feel.

Cons: Pressure point discomfort and motion transfer issues.
