Innerspring mattresses have wire coils as the support structure. An innerspring mattress has a strong border wire attached to the perimeter of the coils. The border wire supports the coils, helping to retain shape and reduce sagging. The edge is reinforced with specially shaped springs or foam to support the sleep surface right to the edge, to help prevent ‘rollout’ and edge breakdown. The upholstery is separated from the innerspring system by an insulator, a tough padding, wire or netting layer that prevents the upholstery from sinking into the coils. There are many types of coils including individual pocketed coils, offset coils, open coils, and continuous coils. The thickness or gauge of the wire also varies quite a bit and the debate continues about which one is best. As each person is different, it is advised to test each one for yourself and then decide. The coil is the heart of the mattress and is very durable. When a mattress is uncomfortable, it is not usually due to the coil faltering rather than the foam layers on top of the coil that compress over time. Higher quality foams such as memory foam or latex foam in these top layers can prolong mattress comfort.
Memory Foam Mattresses
NASA’s Ames Research Center funded a development project in the early 70′s designed to create a substances that would relieve astronauts of the g-forces they experience during lift-off. They found that reducing g-forces on the body was aided by using a material that conforms to a person’s body. Mold could accomplish this but any movement would create incorrect pressure points. To remedy this, they created a foam material that was viscoelastic – able to conform to a shape, but come back to an original shape once pressure was removed. Fagerdala World Foams of Sweden, which at the time was one of Europe ‘s largest foam producers, perfected this type of foam for consumer use in the 80’s.
The Swedish Mattress company, Tempur-Pedic®, introduced this material in a mattress form to the people of Sweden in 1991. In 1992, Tempur-Pedic® launched the products in North America. With the success of Tempur-Pedic®, other foam manufacturers developed their own viscoelastic memory foam materials flooding the market with a variety of options and price levels. With this we also saw the use of viscoelastic foam in products other than mattresses.
The gentle, conforming support of latex foam reduces high-pressure areas that shut off capillary blood flow causing a person to toss and turn. This alleviates pressure and helps bring oxygen and nutrients to your muscles, so you awake feeling recharged and renewed.
Latex foam mattresses do a world of good for your back and spine—in and out of bed. They provide years of comfortable sleep. And never need flipping. Latex foam will not break down and offers exceptional stability to eliminate sleep disruptive motion transfer. Latex is the most resilient sleep technology on the market virtually eliminating body impressions and the sagging center many consumers complain about! So you can rest well from now until the sheep come home…
Latex instantaneously conforms to every curve and contour of your body to keep your spine in a properly supported throughout the night. We further enhance this natural feature by layering softer layers of latex near the surface to reduce pressure without sacrificing support. Latex mattresses offer you the ideal balance of comfort support. This unique, naturally derived material dynamically responds to your every curve and contour to provide outstanding, orthopedic support. It also alleviates sleep-disturbing areas of high pressure, so you sleep deeper and awake refreshed and ready for a new day.
