What are the benefits of a memory foam mattress? Is it worth it to get one? If these are the questions you’re asking yourself while debating whether or not a memory foam mattress is right for you, you’ve come to the right place. 

While it’s important to consider the benefits, it’s equally important to weigh the drawbacks of a specific type of mattress prior to purchase. In this article, we discuss what memory foam is, why it’s consistently a buzz worthy mattress option, and how to determine if memory foam is the best option for your specific sleep habits and hurdles. 

Memory Foam: What It Is And How It Works

Created by NASA in the 1960s, memory foam is a material that contours and conforms to the shape of any object placed on it. Before being used in mattresses, memory foam was used in space travel, shoes, helmets, and hospitals.

Most memory foam is made of polyurethane foam combined with other chemicals creating a viscoelastic foam. This specific combination of elements provides memory foam with its unique ability to   mold to shape in response to pressure and heat then slowly regain its original form after the weight is removed. 

When you lie on a memory foam mattress, your body weight causes the foam to conform to the natural curves of your body. This allows for even weight distribution across the surface of the mattress creating a cloud-like comfort.

Pros And Cons Of Memory Foam Mattresses

Like any mattress type, memory foam mattresses have pros and cons that make them more or less desirable to different sleepers.

If you want to learn more about the differences between other mattress types and which one is right for you, check out our guide to the different types of mattresses.


  • Absorbs motion: Unlike spring mattresses, dense memory foam absorbs movements preventing motion transfer. This is oftentimes popular amongst couples since it avoids  disturbances to either  partner even through tosses and turns during the  night.
  • Cloud-like  comfort: Memory foam mattresses are most recognized for a cushioning plushness and weightless feel. While memory foam provides instant relief, continued comfort is oftentimes not promised. 
  • Widely available: Memory foam mattresses are available in a wide variety of  constructions, technology, and price points making the options seemingly endless.  While you can find a lot of information about specific memory foam mattresses through reviews online, it’s still best to test out a mattress in-store to see if it’s right for you.

Is your sleeping partner sold on a memory foam while you crave comfort of a different kind? Maybe it’s the other way around?  Many don’t know that purchasing  two separate twin beds and joining them together on one base provides the best of the both worlds in a near-king-size mattress. s. Check out our guide to using two twin beds together for more information on the “split king” system. .


  • Heat retention: Due to its  density, memory foam mattresses tend to absorb heat while struggling to dissipate it. . Traditional memory foam absorbs body heat throughout the night  which is oftentimes a pro for cold sleepers but a con for neutral and  hot sleepers. 
  • Temperature sensitivity: The cushioning properties of memory foam are affected by the temperature and humidity of your bedroom. For example, a cooler or drier room causes memory foam to feel firmer, while a hot room causes memory foam to feel  squishy and soft.
  • Difficult to move on: Memory foam mattresses don’t respond to movements quickly making it difficult to move around. Memory foam tends to sink deep with the application of  pressure, instead of adapting to movements unlike the GelFlex® Grid which adapts quickly, relieves pressure, supports and cools.  
  • Price:  Memory foam mattresses tend to be more expensive than  hybrid mattresses and traditional spring mattresses. It’s important to remember that  the cost of a memory foam mattress is usually directly correlated  to its quality and longevity. Typically the higher the cost, the better the materials and construction, the better the sleep. 

Many sleepers choose to add a topper to their mattress to achieve the memory foam comfort withou the cost.  Read our guide on the differences between a pillow top and a euro top mattress to find out which one is the best option for you.
