Understanding Memory Foam: Your Guide to Comfort and Support

Memory foam has revolutionized the mattress industry, offering unparalleled comfort and support for a restful night's sleep. But what exactly is memory foam, and how does it work? In this guide, we'll delve into the science behind memory foam and explore its benefits for a better understanding of this innovative material.


What is Memory Foam?

Memory foam, also known as viscoelastic foam, is a type of polyurethane foam that is temperature-sensitive and responds to heat and pressure. It was originally developed by NASA in the 1960s for use in aircraft cushions to improve crash protection. Today, memory foam is widely used in mattresses, pillows, and other bedding products for its unique ability to contour to the shape of the body, providing personalized support and pressure relief.

How Does Memory Foam Work?

Memory foam is designed to respond to the body's heat and pressure, allowing it to conform to the natural curves of the body. When you lie down on a memory foam mattress, the foam softens in response to your body heat, creating a custom-molded impression that provides targeted support and cushioning. As you shift positions or get up from the mattress, the foam slowly returns to its original shape, ready to adapt to your body again when you return.

Benefits of Memory Foam

There are several benefits to choosing a memory foam mattress:

  • Pressure Relief: Memory foam evenly distributes body weight, reducing pressure points and preventing discomfort. This makes it particularly beneficial for individuals with joint pain or arthritis.


  • Spinal Alignment: By conforming to the natural curves of the body, memory foam helps maintain proper spinal alignment, reducing the risk of back and neck pain.


  • Motion Isolation: Memory foam absorbs motion, preventing disturbances from a restless sleeping partner and promoting uninterrupted sleep.


  • Durability: High-quality memory foam mattresses are durable and long-lasting, retaining their shape and supportiveness for years to come.

Types of Memory Foam

Not all memory foam is created equal. Here are some common types of memory foam found in mattresses:

  • Traditional Memory Foam: This is the original type of memory foam, known for its slow response time and deep contouring properties. It provides excellent pressure relief.


  • Gel Memory Foam: Gel-infused memory foam infuses gel to help regulate temperature and dissipate heat, keeping you cooler during sleep. It offers the same contouring and support as traditional memory foam with enhanced cooling properties.

Integration of Memory Foam in Mattress Models

Let's explore how memory foam is integrated into the Tuck, Lull, Doze, and Sopor mattresses:

  • Tuck Mattress: Features a 1" layer of 3lb gel-infused memory foam in the pressure relief layer, providing personalized support and enhanced cooling for a comfortable night's sleep.


  • Lull Mattress: Utilizes a quilted top with a breathable cover in the comfort layer, 2" of 3lb gel-infused memory foam and 2" of high-density comfort foam in the pressure relief layer (totaling 4"), and an ISO coil support system with wrapped coils for enhanced support.


  • Doze Mattress: Comes with a layer of 2" 4lb gel-infused memory foam and 2" high-density comfort foam in the pressure relief layer (totaling 4"), and an ISO Coil+ support system with wrapped coils for added support.


  • Sopor Mattress: Features a layer of 3" 4lb gel-infused memory foam and 3" high-density comfort foam in the pressure relief layer (totaling 6"), and an ISO Coil+ support system with wrapped coils for superior support.


Misconceptions of Memory Foam

Despite its numerous benefits, memory foam is sometimes subject to misconceptions. Let's debunk some of the common myths:

Fallacy #1) Memory Foam is Too Hot: One of the most prevalent misconceptions is that memory foam mattresses sleep hot. While lesser quality memory foams exist and early iterations of memory foam mattresses had non-breathable covers, modern domestic made mattresses have solved this. In addition, many memory foam mattresses now incorporate cooling technologies such as gel-infused foam or better quality open-cell structures to regulate temperature and enhance breathability

Fallacy #2) Memory Foam Off-Gassing: There's a misconception that memory foam emits harmful chemicals and odors, a phenomenon known as off-gassing. While it's true that some mattresses may emit a smell initially due to the manufacturing process and packaging, it typically dissipates within a few days. All foam emits this and is the main contributor of the "new car smell" people enjoy - although memory foam does not have the same aroma. Most memory foam mattresses are CertiPUR-US® certified, ensuring they meet stringent standards for emissions, content, performance, and durability.

Fallacy #3) Memory Foam is Too Firm: Memory Foam is a very dense foam and that makes it very durable and excellent at relieving pressure. But there is a separate measurement for softness - ILD.

ILD stands for Indentation Load Deflection, and is a measurement of weight to depress a piece of foam. The higher the ILD, the firmer the foam. With a more controlled environment, memory foam has been able to increase it's density and achieve a softer foam. 

The Way Memory Foam is Poured Matters

As foam makers have spent more time refining their processes and upgrading their equipment, the quality of foam has increased. With that said however, there are many smaller factories which pour foam in an archaic manner. These foams are very difficult to control quality, comfort, and performance. When purchasing a mattress from an online marketplace which is imported, you can find some very poor quality foams in mattresses. Make sure it is a brand you trust.


Memory foam is a versatile and innovative material that has transformed the way we sleep. Its ability to conform to the body, relieve pressure points, and promote spinal alignment makes it an excellent choice for individuals seeking comfort and support in their mattresses. By understanding the science behind memory foam and its benefits, you can make an informed decision when choosing the right mattress for your needs.
