Bonnell Springs are made of high carbon steel wires which have good performance in tensile strength and hardness.

Bonnell coils have an hourglass shape that is wider on the top and bottom than in the middle. The thinner portion

is designed to flex in response to minimal pressure, while the thicker portion can stand up to greater pressure.

Each coil is knotted at the end and connected to the neighboring coils via a network of thin, spiral-shaped helical

wires.

Since Bonnell coils are interconnected, they move as a single unit. This allows them to provide more support, but

it means they can’t adjust to different weights and sleep positions as well as other mattress coil styles. Friction from

the coils may also produce some noise.

Bonnell coils were the original type of mattress coils used to make mattresses. They’re also one of the least

expensive types of mattress coil. Bonnell coils are fairly firm and they generally have reliable edge support,

though they can be prone to sagging in the center of the mattress.
