High Carbon Steel Wire Bonnell Spring System Mattress Coil Unit for Mattress Manufacturing Technology

The Bonnell spring features the classic figure eight spring design. Over the last century and a half it has proven its

effectiveness.The hourglass round shape of the spring delivers a good deal of responsiveness.

Bonnell springs are tied together to form a mat around helical cross wires. These connect each spring coil to the

spring unit.The spring unit is completed with four millimeter diameter edge wire and edge wire support clips. This

support prevents the mattresses edges from collapsing when you are sitting on the edge of the bed.

Bonnell spring units are noted for compressing easily at first. However, the more you compress them, the firmer it

becomes. The result of this feature is that mattresses that are fitted with Bonnell springs provide you with a good

mixture between softness and firmness.
