25 Terms You Need To Know Before Buying A Mattress

Monday, October 20th, 2008

Viscoelastic – Anything that shows both viscous and elastic characteristics when deformed. An example of a viscous material is honey. An examples of an elastic object is a rubber band. The difference between elastic behavior and viscoelastic behavior is that a viscoelastic object uses a strain rate dependent on time. Thus, a viscoelastic object loses energy when a load is applied and then taken away.

Natural latex – Occurs naturally from rubber trees. Natural rubber is an elastic hydrocarbon polymer that occurs naturally as a milky colloidal suspension or latex. The latex is found in the sap of some plants other than the rubber tree. Rocky Mountain Mattress uses natural latex in every custom latex mattress.

Organic – Often referred to as organic foods or organic materials. Organic materials are those products that are produced according to certain production standards, often meaning that they are produced without the use of chemicals, toxins, or other materials.

Memory foam – Made from polyurethane. Memory foam often has additional chemicals that increases its viscosity level. This increased viscosity also increases the foam’s density. Most memory foam products are firmer in cooler temperatures and softer when heated. Memory foam that is used for memory foam mattresses use a person’s body heat to warm it up. As it is heated, it molds to the shape of the warm body within a certain period of time. Lower density memory foam is more pressure sensitive. This foam can mold to the shape of the body more quickly.

Green foam – Refers to any foam that is environmentally friendly. This foam is often produced without any added chemicals or toxins. It is also biodegradable. Often times, green foam is safe for the environment throughout the production process and as a finished product. Even the production process of producing green foam is considered “green.”

The Talalay process – A method of producing latex. In this process, molded pieces of natural latex foam rubber are produced. First, a natural latex rubber is put into a closed mold. The mold must have been vacuumed to remove any air particles. Next, the mold is frozen in effort to stabilize the cell structure. Then, carbon dioxide is added to the mold. Finally, the mold is then heated in order to cure the rubber. This process is considered to be “organic” or completely natural.

The Dunlop process – The other method for producing latex. This method is much shorter and more inexpensive than the Talalay process. The Dunlop method is more traditional, is used more often, and produces the only 100% all natural latex product (i.e. no added chemicals, fillers, etc.).

Foamex – The leading producer of comfort cushioning for bedding, furniture, carpet cushion, and automotive markets as well as technical foam for diverse applications in industrial, consumer, electronics and transportation industries.

Bayer – Chemical and pharmaceutical company founded in Barmen, Germany in 1863.

Rocky Mountain Mattress – A company comprised of mattress experts who are dedicated to helping customers enjoy the best sleep possible by offering a wide variety of mattresses, mattress toppers, custom mattresses, adjustable beds and sleep accessories.

FiberLux – The standard Rocky Mountain Mattress micro-fiber cover used on the Sunrise and Sundance mattresses.

Coolmax – Is a brand of technical fabrics designed to wick moisture away from the skin. The fabrics use specially designed fibers to improve “breathability.”

Density – Is a measure of how tightly the matter within it is packed together. In the mattress industry density is often measured in terms of pounds per square foot, i.e. a 5 lb foam weighs 5 pounds per cubic foot of the foam.

Indentation load deflection (ILD) – A term used by furniture manufacturers to measure quality. The firmness of a polyurethane foam cushion is measured by the ILD.

Indentation force deflection (IFD) – Used rather than the ILD method. It is defined as the amount of force, in pounds, required to indent a fifty square inch piece of foam relative to the total foam thickness. Again, this is a quality assurance measure.

Open cell foam – Is made up of thousands of tiny, cell-like components. The walls are called struts and the spaces inside are called voids. Open cell foam makes it possible to conform to your body and relieve pressure points. Because the walls of the cell are not solid, they can deflate when pressure is applied. Additionally, since the struts are made from a resilient material, they bounce back when the pressure is removed.

Component mattress – A mattress composed of separate individual layers of foam, which can be re-arranged according to the sleeper’s preference.

Assembled mattress – A mattress that has been fully manufactured and arrives to the consumer fully assembled

Foundation – aka box spring (without the springs) – refers to the flat rigid surface that a innerspring mattress, air mattress, latex mattress, memory foam mattress, or waterbed must be placed on to achieve maximum support. Rocky Mountain Mattress foundations are made from Southern Pine.

Bioflex medical magnets – Magnets that have been clinically proven to reduce pain, accelerate healing and improve circulation. When used in conjunction with a supportive mattress, they have been hailed as the most advanced and effective products of their kind for their ability to help a person get a good night’s sleep naturally. They can be purchased as a mattress overlay to achieve maximum results.

Custom mattress – Mattresses that can be specially ordered by customers. Customers can specify the correct size dimensions, the arrangement of layers, and foam densities. Customers can also choose to add BIOflex medical magnets, CoolMax by Dupont heat and moisture-reducing fabric, lumbar support and other products.

Memory foam mattress topper – A thinner mattress pad that is designed to lie on top on an existing mattress. They can offer an extra layer of comfort and warmth, especially when the existing mattress is worn or uncomfortable. They can help relieve pressure points too. Memory foam mattress toppers react to both pressure and temperature. These characteristics along with greater density can give the sleeper a “weightlessness” sensation.

Mattress blog – A resource linked to a company’s website that can offer helpful information to the customer. The mattress blog is often a place where you can go to find the information you need in more detail. Customers are free to leave comments and post reviews as well.
