Coconut and Coir

Coconut and Coir Coconuts are not only something you can eat, but something you can sleep on. Coconuts are the fruit of the coconut palm (Cocos nucifera), a tree naturally found on tropical coasts. The coconut palm has spread by means of its bouyant seed floating on water, following ocean currents and tides. From beaches, it spreads to nearby low areas by dropped seeds. Coconuts are rather large and heavy for seeds, so coconut palms do not naturally range far from the shoreline. However,...

Graphite and Diamond Dust: Pencil lead and jewels

Graphite Lump ~~~ Pencil ~~~ Cut Diamond ~~~ Graphite Structure Graphite and Diamond Dust: Pencil Lead and Jewels Several mattresses are described as having foams or fibers infused with graphite or diamond particles. Graphite and diamond are two kinds of carbon crystals. Both are pure carbon, but they differ in the crystalline structure. The structural difference makes diamond extremely hard and graphite relatively soft. Real diamond particles (a.k.a. diamond dust) are very abrasive and...

Polyurethane Foam

One of the common ingredients in mattresses and upholstered is polyurethane foam. In descriptions of mattresses, it is often called "poly foam." With differing densities, resiliency and other characteristics, it can be a base pad, support core, comfort layer, or quilting foam. It was used before the invention of memory foam, which itself was developed from polyurethane. Polyurethane (PU) foam is made by linking large molecules, usually isocyanates, to each other with modified oil molecules...

Latex

Latex is used in several ways in mattresses and bedding. It is commonly used in pillows and mattress pads/toppers. It can be found in cover quilting and comfort layers on innerspring mattresses. Even memory foam mattresses may have a latex layer. Then there are latex mattresses, usually a latex comfort section over a base foam support core. Some latex models also have a latex support core, either (mostly) a high-density and high resiliency latex foam or (seldom) a solid block of...

Mattress Foams – Part 2

(Continued from Part 1) The three major kinds of foam used in mattresses are polyurethane foam, visco-elastic memory foam, and latex foam. Each kind of foam has variations. First, there are different ingredients in these foams. Then there are different densities and firmness levels. Now gel is infused into different foams to add desired characteristics. Polyurethane Foam Polyurethane (PU) foam is made by linking large molecules, usually isocyanates, to each other with modified oil...
