Memory Form Mattress Facts:

Spring mattress core

The core of the mattress is the most important part in the support of the body. In most modern mattresses (except for the foam-only ones), it is made up of steel coils springs, also known simply as coils.

The steel coil spring was invented during the industrial revolution and was first patented for use in a chair seat in 1857.

Then, in 1871, Heinrich Westphal invented the innerspring mattress. He lived in Germany and died in poverty, having never profited from his invention.

Offset coils

Bonnell coils evolved into Offset coils, which are currently popular, but happen to be the most expensive ones. They are almost identical to the Bonnell coils, except that the top and bottom circular part of the coils have flat or straight sides, which allow for better hinging action when they are placed together in a spring unit, and which can be easily aligned.

Brands as Stearns and Foster use regular Bonnell coils in their mattresses. An evolution of the offset coils brought the elimination of the knot that tied the end of the wire to the coil.

In other words, offset coils might be tied off or feature a loose end (sensory arm). These are called "open end offset coils". These improvement gave offset coils an extra turn of working wire for greater spring action on each end of the coil. However, loose ends increase the odds that a spring will begin to punch through the padding. Brands like Sealy and Spring Air use open end offset coils in their mattresses.
