What makes memory foam mattresses so good? It's all about the materials. We will dive deeper into what a memory foam mattress is made of and cover these;
In memory foam, polyurethane is primarily used along with chemicals to increase its density and viscosity. It is also known as viscoelastic polyurethane foam or low-resilience polyurethane foam (LRPu). Open bubbles or 'cells' in foam create a matrix in which air can move.
Efficient mattresses don’t just offer a good night’s rest but also keep your back pain in check. It’s evident from stats that around 16 percent of the Australian population suffers from back pain.
Much of the back pain originates while sleeping. Also, a lot more weren’t satisfied at all with the quality of sleep they were getting. So at this point, it won’t be surprising that the answer might simply lie in the mattresses.
NASA perfected the concept of memory foam. Yes, we’re talking about the National Aeronautics and Space Administration. The concept isn't even close to new. The collaboration between Stencel Aero Engineering Corporation and NASA occurred in the 1960s.
Charles Yost invented memory foam in 1966 while he was trying to create padded seat cushions for NASA spacecraft that could withstand the pressure caused by G-forces during takeoff. Even though NASA didn't use his design, it appeared in car seats, medical equipment, and eventually mattresses.
Memory foam is also known as viscoelastic foam, which belies its essential properties: it becomes viscous and elastic when subjected to heat and weight. As a result, it’s excellent for relieving pressure on sensitive parts of the body like the back, shoulders, hips, and spine.
To give memory foam its viscosity, polyurethane polymer is combined with hard-working chemicals.
Memory foam is made of polyurethane foam, containing three different chemical components: polyols, diisocyanates, and a carbon-based blowing agent. By combining these three components, a chemical reaction is triggered, which produces a liquid. As the liquid cools, it hardens into foam.
In a reaction with isocyanates, polyols are converted into polyurethane foam. The foam's bulk is polyols.
Diisocyanates are commonly used to make rigid and flexible foams (such as memory foam products), sealants, adhesives, and more. There are two types of diisocyanates used to make memory foam: MDIs and TDIs. You're likely to see MDIs in home insulation, sealants, weather-resistant materials, or binders. TDIs are most common in furniture, bedding, and packaging. For example, mattresses contain large quantities of both TDIs and MDIs, but they are not carcinogenic.
In the process of converting liquid to foam, blowing agents are used. Chlorofluorocarbons (CFCs) are the most commonly used blowing agents in memory foam. Today, many mattress makers use safer blowing agents, such as water.
VOCs are organic compounds that are produced by the three materials listed above. For example, it is typical for a newly opened memory foam mattress to emit a chemical smell - these are VOCs. Exposure to VOCs is not harmful, but it may irritate those with allergies or respiratory problems. Off-gassing odours usually dissipate after a day or two, but if they persist, you can open the windows and air the room out.
Not at all. In contrast to memory foam, polyurethane foam, or poly-foam, is different. This type of foam is cheaper, and therefore of lower quality.
Likewise, poly-foam comes in different densities, but the higher the density, the more durable the foam. While it can provide some cushioning, it does not offer the same level of individualized support as memory foam. You will commonly see this material as a support layer to a memory foam comfort or top layer. However, this will be high-density polyurethane foam for durability.
Memory foam is very similar to reflex foam; it's just constructed differently. Although faster reshaping is one of its distinguishing characteristics, and it’s a little firmer than memory foam, it makes a great base layer or component for supportive orthopaedic mattresses.
Orthopaedic and medical memory foam is designed specifically to relieve chronic back pain and joint ache. To provide extra cushioning around joints and problem areas, the foam is carved with grooves and channels.
Heat and compression are used to bond latex particles into a solid form. Both synthetic and natural latex can be used to make mattresses.
Latex does not soften when in contact with body heat, so some people may find it too firm. Also, natural rubber has excellent eco-credentials as well as being a durable material.
Not always. Depending on your sleeping style and preferences. Hybrid mattresses combine the best features of several mattresses into one. For added comfort, spring mattresses are often combined with a layer of memory foam.
When you have specific sleeping needs, like getting too warm at night or having different mattress support standards between you and your partner, a hybrid mattress could be the right solution.
Don't worry if the mattress feels a little firm here and there. The more you use it, the quicker it will adapt to your needs. This is due to its viscoelastic properties.
If you don't want to wait that long, you can also increase the temperature of your bedroom. Now let's talk about sleeping on a memory foam mattress. Then, when you get out of bed, the foam springs back to its original shape after a short time.
Step 1: Go ahead and get the mattress out of the box.
Step 2: Lay it down on your bed.
Step 3: Remove the vacuum-sealed packaging and unfold it.
Step 4: Let it sit until it takes the shape of the mattress.
Try to leave it as long as possible before sleeping on it, usually 24 hours.
You can sleep on a memory foam mattress in a variety of ways. Here are a few of them.
In the long run, sleeping sideways is not only comfortable but also good for your health. If you like to sleep on your side, memory foam mattresses provide excellent pressure relief and are perfect for you.
Spine overarching is common if you’re sleeping facing the mattress. Since a memory foam mattress adapts to the shape of your body, it provides support for your spine. But most memory foam only mattresses might be too soft to get proper support in this position.
Sleeping on your back has many health benefits. The reason is that when you sleep in that position, you're able to distribute your body weight on the mattress evenly.
However, it might also be the reason you wake up with sore lower back muscles. When this happens, it is a clear sign that you need to change your mattress. If you are, there's nothing better than a memory foam mattress.
Memory foam mattresses can significantly impact sleep and spinal health. Among the benefits are;
A good foam mattress will have multiple layers of foam and a study base which would generally be high-density foam. Due to this, the mattress can provide excellent breathability and support. Below are two excellent memory foam mattress picks.
Emma stands at the top of the memory foam mattress world. So when you are looking for a mattress that offers high reviews and fantastic comfort, this is the mattress you should consider.
More so, its layers of foam provide the perfect comfort level for side sleepers. Plus, if you love memory foam, get yourself mattresses from Emma. For more information, check out our Emma mattress review.
Koala is a brand that perfectly reflects the sleeping needs of Australians. It offers mattresses that are "not too firm, not too soft." In addition, Koala foam mattresses are eco-friendly. They have, however, recently moved production of the mattress to China to cut costs, but the reviews haven't mentioned the quality of the mattresses they offer.
