Support System: Bonnell coils are the oldest and most common. First adapted from buggy seat springs of the 19th century, they are still prevalent today. The Bonnell spring is the classic spring unit, and has proven its worth through the years. It is made from round hourglass-shaped springs, which are tied together to form a mat. A round helical crosswise connects each single spring to a spring unit. The Bonnell spring unit is suited to 1-person sleep but is still acceptable as a 2-person sleep.
