Mattress Inner Bonnell Spring Unit With High Carbon Steel Wire

Mattress coils are metal springs that support the mattress and form a durable surface on which to sleep. They’re

designed to flex in response to pressure and movement, providing progressively firmer support as more pressure

is placed on the mattress.

The Bonnell style has been around for many years and is still a standard method of manufacturing. It is made from

around hourglass shaped springs, which are tied together to form a mat. A round helical crosswise connects each

single spring to a spring unit. Wrapped in poly padding foam the Sleep Aid will have you sleeping in no time.
