First developed in the 19th century from the buggy spring, this particular coil configuration is the most widely "consumer tested" innerspring on the market.
Its "knotted" hourglass shaped coils ") (" are "laced" together with spun "helical" wires at the top and bottom ("foot") of each coil. The entire shape of the unit is defined with heavier gauge "border wires" that are generally clipped to outer perimeter coils.
In certain configurations (coil count, wire gauge) this unit is extremely durable and can take quite a number of years of rigorous use before eventually losing its "temper memory".
Because of its wide availability due to many sources of supply (including offshore manufacturers) this unit's pricing is very competitive and, therefore, is used quite frequently in promotionally priced products. But, because of its durability, it is also used quite frequently in hotel and motel applications, university dormitories, and, yes, even in upscale bedding.
Carpenter, a leading supplier of foams and fiber has invented a new cushioning foam they've dubbed Serene™. The new foam features billions of microscopic air capsules which act to enhance support properties while reducing pressure on critical areas like hips and shoulders. Serene™ is less temperature sensitive than memory foams. In fact, our plant manager took a 6 inch cube of Serene™ and put it in his freezer for 3 days. The foam compressed as if it had been kept at room temperature.
Serene™ has been demonstrated to dissipate heat faster than memory foam. Serene™ is far more durable than a comparably dense piece of memory foam and is as or more durable than a memory foam that is almost twice as dense.
Because of these characteristics and more, we have been experimenting with some prototypes featuring a hybrid design of a stratified core with a thick piece of Serene™ on top. We have also been experimenting with combinations of Serene™ and Talalay Latex. Those combinations have produced some incredible feels and will be available soon both on our retail floors and at our dealers.
