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.
