A visco memory foam bed may feel too soft at higher temperatures. If the environment where you try the bed out feels warm, the entire bed may become softer. That does not necessarily indicate a poor quality bed, but it means you must choose wisely, based on the temperature of your home or the climate where you live in.
Is visco elastic memory foam hot?
Since a viscoelastic mattress made of pure viscoelastic foam would not provide any opposing pressure, these mattresses are always apart of a two-part construction. Under a layer of viscoelastic foam, the mattress usually has a cold foam or spring core.
Does memory foam make you hot?
Unfortunately, the same properties that make them so comfortable also tend to make them sleep hot. Memory foam is notorious for trapping body heat. Its density makes it less breathable than other materials, while its body-hugging properties make it more likely to absorb and contain the body heat of the sleeper.

Why do I get so hot at night?
1. You Have a High Metabolism. Body temperature naturally rises as it burns food to fuel itself — so it's only logical that a higher rate of metabolism would result in an overall higher body temperature. As such, people with a high metabolism are more susceptible to overheating at night.
What is Visco Elastic Memory Foam?
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 re-appropriated into a number of things including mattresses, bed toppers and much more.
How Does the Quality of the Memory Foam Affect my Mattress?
Each of our memory foam mattresses provide at least 4 lbs per ft density which ensures that your mattress will be comfortable and resilient enough to maintain its shape for years to come.
What is memory foam?
Memory foam. Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as " viscoelastic " polyurethane foam, or low-resilience polyurethane foam ( LRPu ).
How does memory foam work?
Memory foam derives its viscoelastic properties from several effects, due to the internal structure of the material. The network effect is the force working to restore the structure of the foam when it is deformed. This effect is generated by the deformed porous material pushing outwards to restore its structure against an applied pressure. There are three effects which work against the network effect: the pneumatic effect, the adhesive effect, and the relaxation effect. These, combined, effectively slow the regeneration of the original structure of the foam, and allow for applications like memory foam mattresses. The pneumatic effect is caused by the time it takes for air to flow into the porous structure of the foam. The adhesive effect, or adhesion, is caused by the stickiness of the surfaces within the memory foam, which work against decompression, as the internal pores within the memory foam are pressed together by an applied pressure. The relaxation effect is the largest magnitude of the three forces working against expansion, and is caused by the memory foam’s material being near its glass transition temperature. This limits the mobility of the foam’s material, forcing any change to be gradual, slowing the expansion of the foam once the applied pressure has been removed. Since this is temperature-dependent, the temperature at which a memory foam retains its properties is limited. If it is too cold, the memory foam will harden. If it is too hot, the memory foam will act like conventional foams, easily springing back to its original shape. The underlying physics of this process can be described by polymeric creep.
Why is memory foam used in medical settings?
For example, it was commonly used in cases where the patient was required to lie immobile in their bed on a firm mattress for an unhealthy period of time . The pressure on some of their body regions impaired the blood flow to the region, causing pressure sores or gangrene. Memory foam mattresses significantly decreased such events.
How to measure memory foam firmness?
The property of firmness (hard to soft) of memory foam is used in determining comfort. Firmness is measured by a foam's indentation force deflection (IFD) rating. However, it is not a complete measurement of a "soft" or "firm" feel. A foam of higher IFD but lower density can feel soft when compressed.
When did NASA release memory foam?
When NASA released memory foam to the public domain in the early 1980s, Fagerdala World Foams was one of the few companies willing to work with the foam, as the manufacturing process remained difficult and unreliable. Their 1991 product, the " Tempur-Pedic Swedish Mattress" eventually led to the mattress and cushion company, Tempur World.
When was the third generation of memory foam introduced?
In 2006, the third generation of memory foam was introduced. Gel visco or gel memory foam consists of gel particles fused with visco foam to reduce trapped body heat, speed up spring back time and help the mattress feel softer.
What is the pneumatic effect of memory foam?
The pneumatic effect is caused by the time it takes for air to flow into the porous structure of the foam. The adhesive effect, or adhesion, is caused by the stickiness of the surfaces within the memory foam, which work against decompression, as the internal pores within the memory foam are pressed together by an applied pressure.

How to reduce temperature of mattress?
1. Enable Maximum Airflow Underneath the Bed. Choosing a bed frame that promotes ample circulation can also help decrease the temperature of your mattress. As mentioned above, memory foam is rather dense and not the best with circulation. This makes the frame you put in on extra important.
How to get airflow in a bedroom?
An easy way to promote airflow in your bedroom is by opening a window. In colder months a fan can also do the trick. If outside noise is a problem, the fan option may be best year round. Some find the ambient noise to be soothing as well.
How to cool off before bed?
Just like a shower or bath, drinking a glass of cold water will help you cool off before getting into bed. This will help ensure you are not adding any warmth from your body from the start. Don’t overdo it though or you may find yourself waking up in the middle of the night in need of the bathroom.
Is memory foam mattress hot?
Are memory foam mattresses hot? Not independently. The problem lies in their heat retention after you add body heat. It builds up overnight and unless you change positions quickly it does not have enough time to release and return to its neutral temperature. Heat buildup worsens with couples.
What Is Viscoelastic Foam?
Viscoelastic is also a term used for memory foam. The only difference is it is made of adding several other substances along with polyurethane foam.
Top Features of Viscoelastic Foam
One of the best features of viscoelastic foam is that its low resilience helps the foam to sink and rise slowly with some pressure. Thus, these are more often used in bedding.
Memory Foam in Comparison to Viscoelastic
Memory foam products were invented in the later stages to promote sleep and blood circulation. Once again, these are also used in mattresses, toppers, bedding craze, hybrid mattresses, etc.,
Viscoelastic Vs Memory Foam
Foams can be of various types: memory foam, latex foams, and polyurethane. Memory foam is a type of polyurethane that is resistant to hear and possesses lower resistance. These are generally used on the surface layers of mattresses.
Why is Memory foam better in comparison with Viscoelastic?
Memory foam is known for its dense layers. If you have to compare with polyurethane foam, memory foam has more resilience. To add more, these are perfect for those looking for warm and cozy mattresses in chilly winters.
What is visco elastic foam?
Visco elastic foam is another term for memory foam. It is a blend of polyurethane foam that was developed for airplane cushions by a NASA contract in the 1970s.#N#The difference between visco elastic foam and other types of polyurethane foam is its slow response and low resistance. Its soft surface allows for contouring and its slow response lowers bounce.#N#Visco elastic foam, like all polyurethane foam, is made from a blend of substances and has a tendency to off-gas. Those with lung sensitivities should do additional research about the quality of foam to ensure that it won't aggravate them.#N#Pros: Contouring comfort, competitive pricepoints, and widespread options.#N#Cons: Sagging and off-gassing problems with lower quality foams.
What makes memory foam contour?
In plain English, what makes memory foam is its ability to contour to pressure and return to its original shape slowly after pressure is released. This process allows for it to react to pressure differently across its surface and provide a contoured, but aligned feeling for sleepers.
Why does memory foam sag?
In mattresses, older or lower quality memory foam may sag from the repetitive pressure of laying or sitting. For this reason, those that are heavier should do additional research about soft memory foam bedding as they will sink more than alternatives and could lead to discomfort for some body types.
Does visco elastic foam have a tendency to off gas?
Its soft surface allows for contouring and its slow response lowers bounce. Visco elastic foam, like all polyurethane foam, is made from a blend of substances and has a tendency to off-gas. Those with lung sensitivities should do additional research about the quality of foam to ensure that it won't aggravate them.
