Like everything in this world, the mattresses we sleep on also undergo constant innovation. To help the end-user sleep well, manufacturers invest heavily to create the best product. However, this can confuse end-users when they try to understand the differences and benefits of these advancements. If you feel the same about Latex vs. Memory Foam Mattresses and cannot decide between the two, read on.
What are Memory Foam Mattresses?
As the name suggests, memory foam mattresses can conform to your body’s shape and help prevent discomfort. When left vacant, the memory foam mattresses return to their normal shape. How does it happen? The answer is Polyurethane. With innovative additions to polyurethane, memory foam mattresses are made energy-absorbent. Many people like how it cushions pressure points. If you have joint or back pain that doesn’t go away, see a doctor.[1] Memory foam is a synthetic material. Look for CertiPUR-US certified foam, which is made without certain flame retardants, heavy metals and formaldehyde and is tested for low emissions.[2] Polyurethane is also essential in every memory foam mattress. But not every mattress with polyurethane has to be a memory foam mattress.What are Latex Mattresses
Latex foam mattresses have a very short memory. This means they quickly return to their original shape when you press on them and lift off. Some people like this bouncy feel; others prefer memory foam’s slower sink. You will most commonly find two types of latex used to make mattresses—synthetic and Natural Latex. You will also find a blend of these types, creating a third variant of latex mattresses.Comparing Memory Foam and Latex Mattresses
Next, in our discussion on latex vs. memory foam mattresses, we will discuss both types in more detail. Let’s start with the construction and different mattress types under these two domains.Construction and Types
Memory Foam Mattresses In technical terms, memory foam mattresses’ ability to return to their shape is called Viscoelasticity. Besides polyurethane, other chemicals help memory foam mattresses take shape. However, memory foam mattresses can have a wide set of properties. They can come in any firmness level. Manufacturers can also add materials like gel, gel beads, copper, and graphite to diversify them. Depending on these construction configurations, memory foam mattresses have different response times. Different layers of materials are joined together to make a single memory foam mattress. They range from high-density support foam at the bottom to gel foam at the top, with transition foam and viscoelastic foam in between. This is the basic configuration of memory foam mattresses. Latex Mattresses Latex mattresses are either all-natural, synthetic, or a mix of both. You can get any of the three types based on the underlying process used to make them. These processes are:- Dunlop Latex – The latex is poured into a pre-made mold. The required material is poured all at once. As a result, these mattresses have greater density at the bottom and softness at the top.
- Talalay Latex – These types of latex mattresses are softer than Dunlop Latex mattresses. During production, the mold is partially filled with the required material and partially with air. This process gives the mattress the consistent softness you feel throughout.
Comfort and Feel
Memory Foam Mattresses One of the best things about a memory foam mattress is its ability to adjust to the body’s contours. Those who want a deep-hug experience from their mattresses should go for it. Side sleepers often like how it cushions the shoulders and hips. Latex Mattresses Latex mattresses have a higher bounce and less compression than memory foam mattresses. They suit people who like to move easily and sleep on top of the bed rather than in it. Latex mattresses offer less contouring precision than memory foam mattresses.Heat Retention
Memory Foam Mattresses This is one of the most distinguished pitfalls of memory foam mattresses. They retain heat. Sweating and humidity are not great companions for a memory foam mattress. However, the manufacturers can bypass this drawback with various cooling techniques. If you hear that a mattress has infused cooling gel or more open foam cells than others, that is not an inherent property. Latex Mattresses Latex has an open-cell structure, and many latex layers have pinholes from the mold, so latex usually sleeps cooler than traditional memory foam.[3]Firmness
Memory Foam Mattresses If you get your hands on a small piece of memory foam mattress that fits in your foam, try pressing it. You will feel less resistance. This is because memory foam mattresses are soft and spongy. Because of this, they take time to return to their original shape and adjust better to your body’s contours. Latex Mattresses The same happens with latex foam, which can feel like pushback when you press on it. That’s why some people find latex firmer than memory foam of the same rating.Allergies and Dust Mites
Memory Foam Mattresses Neither material stops dust mites on its own, since mites live in bedding and on mattress surfaces. For dust mite allergy, allergy groups recommend a zippered allergen-barrier cover and washing bedding weekly in hot water.[4] Latex Mattresses Natural latex comes from rubber tree sap. It can cause reactions in people with a latex allergy, so check the materials first if you have one.[5]Conclusion
This brings us to the end of our discussion on latex vs. memory foam mattresses. Both types of mattresses have distinct properties and characteristics. One set of properties suits one group of users, and the other suits another. Ultimately, it depends on your needs and requirements. Plus, you are looking for a certain experience from your mattress.Sources
