Firmness is the most important consideration in a mattress...
When it comes to a comfortable night's sleep, nothing is more important that a mattress that has the perfect combination of support and conforming comfort for your size, weight and sleeping position. The variations in firmness requirements can be considerable, as foam has a different firmness and feel based on the weight and shape of each person. What's firm to someone at 120 lbs will often not feel supportive to someone weighing 190 lbs.
One thing is certain, these different firmness requirements cannot be solved by a plushy pillow top or euro top mattress that temporarily hides the discomfort of inner springs. Ask anyone who has had a body impression quickly develop in their mattress, as the top layers of foam break down, and they will assure you, the better the foam, the more durable the mattress.
Layering create the perfect individual firmness in a mattress...
The top layer or layers of your mattress are designed to to create an comfort zone that conforms to the weight, shape and sleeping position of each individual. However, these comfort layers must work in tandem with the supportive core of your mattress to offer optimum support!
Using our 10" Nu-Lex Talalay latex mattress, with two 2" conforming layers, as an example, five different firmness variations are available in the conforming layers. Someone slightly built, sleeping on their side, who enjoys a softer feel in a mattress, might choose to have both 2" layers soft, while larger individuals or back sleepers can opt for the firmer options.
While the top layers of your mattress are generally softer to conform and reduce, or eliminate, pressure points, the mattress core is designed as the primary support of your mattress. Natural latex, particularly Talalay latex, is the most comfortable of all mattress materials, providing incomparable support, while still conforming to your body shape and sleeping position.
Natural latex cores, or support layers, out perform all other materials such as inner springs, commonly considered to create pressure points, or the stiff polyurethane foam cores in mattress such as a Temper-Pedic, or other memory foam mattresses.
Let's start with the Okeo-Tex Standard 100, the universally acknowledged highest testing standard for no harmful substances. The Standard 100 states that "overall the test criteria clearly exceed existing legislation and often have a pioneering function regarding legal regulations."
Not only does natural meet these standards, but it also has unsurpassed durability, with warranties that generally run 20 years. Natural latex is harvested from sustainable rubber trees, and is hypoallergenic, anti-microbial, while naturally resisting mold, mildew, bed bugs and dust mites.
