Bonnell Spring:
Bonnell coils are the original design used in the first spring mattresses, and some manufacturers still use them today. They are hourglass-shaped and can be made to be either soft or firm depending on the wire gauge.
Bonnell coils are simple and cost-effective, so many mattresses utilize them.
