Mattress Surfaces

Springs are the foundation of a mattress providing the essential posture support. It is the upholstery and filling which provides the all-important comfort element.

Fabrics and ticking have many different characteristics, however more luxurious and more expensive fabrics will generally wear better, provide better insulation, will have a softer handle, absorb moisture better and will aid in achieving a more restful sleep.

Springs

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 spring mattress core is also called innerspring. It provides support to the set. Proper support is where the wire coils push back in response to weight deflection to hold the body in alignment.

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.

Coils

Obviously, heavy gauge (thick) coils will offer a great deal of support while light gauge coils will give less support. A low coil count and heavy gauge wire can pass as a firm mattress in the store, but it is likely that this mattress will become lumpy quickly because it does not have enough coils and is the key characteristic of poor value bed. All Clerys beds and mattresses must conform to a standard which will deliver a life expectancy associated with a quality bed.

Many premium mattresses feature 14-gauge (1.63 mm) coils. Coils are measured in quarter increments. The lower the number, the thicker the spring. With coils of 14 to 15.5 gauge (1.63 to 1.37 mm), it is important that the total coil count be high to compensate for the fact that they give so easily under pressure. A 12.5 gauge (1.94 mm) innerspring, the thickest typically available, may feel rock hard in a double mattress even with a coil count of 400 or less.

Pocket Springs

In view of the high comfort and the various application possibilities, the bag spring core is very popular. Here – as the name already suggests – the individual springs are housed in small cloth bags.

The spring strands that arise as a result are connected to each other in various ways. The bag spring core distinguishes itself through its absolute absence of sound. Further advantages are the very high point elasticity as well as the active body support. This is because while lying, only those springs that are subjected to a load yield to the weight.
