Bonnell coils are often referred to as the old standard coils, if you bought a mattress 50 years ago, this was the innerspring the majority of mattresses were made with. Today there is a huge misconception that these coils are “cheap” and won’t last as long. New Bonnell coil mattresses feature more “turns” in the coil than in the past making them very durable especially when combined with a heavier gauge of wire.
Bonnell coil construction can vary greatly in both the number of coils used in its construction as well the shape, design and gauge of the coil itself. It is important to understand that the number of coils does not necessarily impact the comfort level of the mattress. The quality of the coil wire (or wire gauge) and how the coils are connected to each other can greatly affect how many coils are used in the construction of any given mattress.
Bonnell coils are hour-glass shaped, which means their resistance increases with load. Many mattress stores will try and sell against this type of coil system because it is the least expensive kind of coil to produce, and therefore they are typically found in less expensive mattresses.
