Visco Elastic Foam was developed by NASA more than 50 years ago to react to body height and weight to contour the body and provide much more comfortable transportation into space and re-entry into the atmosphere. Since its inception, it has been reappropriated into a number of things including mattresses, bed toppers and much more.
Visco Elastic memory foam is designed to react to body heat and weight to conform to the body, and to return to its original state once the heat is removed. When used in a mattress this effect produces a personalized comfort in the mattress that is unparalleled in any other mattress technology.
The conforming effect of the memory foam reduces pressure points typically found in an innerspring mattress. This helps you get to sleep faster, and stay asleep longer, so you can wake the following morning refreshed and ready to take on your day.
This memory foam can be made in almost any comfort level you desire. This ensures that no matter what position you sleep in, that a memory foam mattress will provide you excellent comfort.
The body contouring effect helps reduce pressure points in the body which minimizes tossing and turning. It also does not transfer motion across the bed. What does this mean for you? If you have a partner that tosses and turns through the night or ends up having to get up several times a night, or gets up earlier than you to start their day. The movement they create in getting up is far less likely to wake you up as it won't shake the bed. This ensures you get the most out of your nights sleep, with far fewer interruptions.
Visco Elastic memory foam has been improved over the years to address a number of issues and provide much better comfort and support. Many people used to run into heat retention issues, and would wake up sweating in the middle of the night because their memory foam mattress retained all of the heat. Since then, gel memory foam and open cell structure memory foam have been released to help address this issue.
Gel Memory foam is the combination of memory foam and millions of gel beads that help provide the best in pressure relief and is 12X more effective at dissipating heat that traditional memory foam.
Open cell structure memory foam has a lot in common with traditional memory foam but is structured in such a way that the cells are able to breathe much more easily, promoting airflow and reducing heat retention.
Mattress manufacturers such as Sealy have included other materials in their mattresses to further improve the temperature regulating properties of their memory foam mattresses. The Hybrid Premier and Optimum mattresses use OUTLAST, which provides superior temperature regulating benefits. OUTLAST is the same material used in a lot of different sports apparel, as well as astronauts suits to help keep the astronauts a uniform temperature.
The density of the memory foam is the biggest factor in determining whether or not the mattress will provide quality comfort and support. Each of our memory foam mattresses provide at least 4lbs/ft density which ensures that your mattress will be comfortable and resilient enough to maintain its shape for years to come.
