> Specialty Foam

All-Foam mattresses provide a broad range of different feels that deliver varying levels of conformance and support. A high quality All-Foam mattress will generally offer a sense of cradling comfort while delivering the lowest motion transfer from side to side. Foam mattresses often conform precisely to the natural curves of a sleeper’s body, thereby providing optimum pressure relief. Pressure points in the hips and shoulders are usually minimized in a well constructed All-Foam mattress. Consumers who purchase high-quality All-Foam mattresses often report that they feel as if they are “Sleeping In” the mattress. In many All-Foam mattresses, a variety of advanced polyurethane and natural plant-based comfort and support foams work together to create unique feels. Whether choosing a product that features visco-elastic foam, latex foam, or other advanced foam configurations, high quality All-Foam mattresses can provide a great night’s sleep. Polyurethane foam, viscoelastic memory foam, and latex foams are the three most common foams utilized when creating a mattress. In recent years these have been joined by infused foams that deliver additional high performance benefits.:

Polyurethane Foam -

Many mattress manufacturers use polyurethane foam in the quilted layers and as the comfort layers of both Spring
+ Foam and All-Foam mattresses. With the advent of roll-packed mattresses, polyfoam is often used as a base layer in their mattresses instead of using spring coils. Several different varieties and densities of polyurethane foam are available. Higher density polyurethane foams are more durable than lower density foams. Many advanced features are available in poly-foam layers including convolution, and varying densities and softness ratings. High quality polyurethane foams carry the Certi-PUR US emission certifications. Consumers are often familiar with polyurethane foam as the type of foam used in sofa cushions or encounter polyurethane foam when shopping for mattress toppers, including “egg crate” mattress toppers. Polyurethane foam is comprised primarily of petrochemicals.

ViscoElastic Foam

Also commonly referred to as “Memory Foam,” viscoelastic polyurethane foam is a type of polyurethane foam that contains added compounds which change the way it responds to pressure and which makes it reactive to changing temperatures. Chemists have engineered Memory Foam for additional conformance and pressure relief, which often results in slower recovery. For example, Memory Foam continues to display a handprint for a few seconds after a hand is removed. Memory Foam is usually denser and more expensive than regular polyurethane foam. Memory Foam is also temperature reactive, which means it absorbs heat and softens as it becomes warmer. Newer versions of Memory Foam known as “Open Cell” visco foams are designed to dissipate heat once absorbed. Many Memory Foams will become firmer in cooler environments and are not recommended for environments where the temperature often dips below 60 degrees Fahrenheit. As with polyurethane foam, Memory Foam is made up primarily of compounds derived from petrochemicals.

Latex Foam -

Latex foam is one of the most durable types of foam available. Latex reacts instantly when pressure is applied and the support it provides changes with your every move. Latex foam does not “sink in” either initially or during the night and maintains constant support regardless of temperature. The responsive nature of latex facilitates easy movement throughout the night, without producing sleep interruption. Latex foam can be produced with natural latex, which is harvested from rubber trees or synthetic latex, which is produced from petrochemicals, or can consist of a blend of both natural and synthetic elements.

Infused Foams –
The chemists and engineers who work for foam manufacturers are on a constant quest to create polyfoams and latex foams with unique comfort, support, and performance properties. Many natural and synthetic additives are now commonly found in the comfort and support layers of modern mattresses. These include cooling gel, copper, and graphite. Each type of infusion offers one or more specific benefits for the consumer.

In addition to use in All-Foam mattresses, consumers will find that each of the types of foam outlined above can be incorporated into a spring mattress as a comfort or support layer.
