Bonnell spring Characteristic
The Bonnell spring is the classic Spring Unit, and through the years, proven its worth. 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. The quality is guaranteed by the careful selection of the materials used and regular quality control.
