Bonnel Spring Series
Bonnell coils are the oldest and most common. First adapted from the buggy seat springs of the 19th century, they are still prevalent in less expensive mattresses. Bonnell coils are hourglass-shaped, and the ends of the wire are knotted or wrapped around the top and bottom circular portion of the coil and self-tied, which means their resistance increases with load. They are therefore best suited for firm mattresses.
