Memory foam and gel memory foam are popular materials used in mattresses and pillows. They both offer unique benefits and are designed to provide comfort and support during sleep. In this article, we will delve into the differences between memory foam and gel memory foam beds, exploring their construction, properties, and how they affect sleep quality. So, let’s dive in!

What is Memory Foam?

Memory foam, also called viscoelastic foam, is created by treating polyurethane foam with specific chemicals to increase its density and viscosity. This unique material molds itself to your body’s contours, offering relief from pressure points. Memory foam is responsive to both heat and pressure, allowing it to conform to your body, providing a cradling and comfortable experience.

Memory foam mattresses have become popular for their ability to react to temperature and pressure. They adapt to your body’s shape, ensuring the right balance of cushioning and support. Since its introduction to the market in the 1990s, the memory foam bed has evolved significantly to overcome one of its initial drawbacks: heat retention. Traditional memory foam mattresses initially featured a closed-cell structure, which could trap body heat and make the mattress uncomfortably warm.

Manufacturers have since improved traditional memory foam beds by transforming them into open-cell structures by injecting air into the material. Nowadays, most memory foam mattresses have an open-cell design, promoting better airflow and enhanced breathability. This innovation has effectively addressed the issue of heat retention, making these mattresses sleep cooler while retaining their excellent body-conforming and pressure-relieving properties.

Benefits of Memory Foam

  • Pressure Relief: Memory foam evenly distributes your body weight, reducing pressure points and improving sleep quality.
  • Motion Isolation: It minimizes motion transfer, ensuring that you and your partner aren’t disturbed by each other’s movements.
  • Longevity: Memory Foam mattresses are known for their durability and can last for many years.

Drawbacks of Memory Foam

  • Heat Retention: Some individuals may find that Memory Foam mattresses retain heat, leading to discomfort during hot nights.
  • Initial Odor: New Memory Foam mattresses often emit a chemical smell that can take a few days to dissipate.

What is Gel Memory Foam Mattress?

Gel memory foam mattresses are crafted using different methods, including adding gel beads, incorporating gel beads, infusion of liquid gel, or adding gel layers on top of the comfort layer. This gel component plays a crucial role in dissipating heat, ensuring a cooler sleeping experience while preserving the original qualities of memory foam, such as contouring the body and relieving pressure.

The specific composition of the cooling gel is a closely guarded secret held by mattress manufacturers. Some mattresses feature thermal or gel-infused memory foam that absorbs body heat to lower the overall body temperature, while others utilize chemicals called “phase-changing materials” or “PCM.” These materials start as solids at room temperature and transition to liquid through body heat. However, there have been some concerns that the cooling effect of gel memory foam may be temporary, as once the PCM changes from a solid to a liquid state, it could potentially trap heat within the mattress.

It’s important to note that the cooling capabilities of gel memory foam can vary between different mattresses. The performance of gel memory foam is also influenced by the overall structure of the mattress and the individual’s body temperature during the night. For example, gel memory foam in a hybrid mattress tends to perform better than in an all-foam mattress, as coil layers in the hybrid enhance breathability. In all-foam mattresses, elements such as the mattress cover material, breathability, and heat retention can impact the performance of the gel memory foam layer.

Benefits of Gel Foam

  • Enhanced Cooling: Gel Foam’s unique composition helps dissipate heat, making it the best choice for hot sleepers.
  • Pressure Relief: It provides excellent pressure relief, contouring your body’s shape and reducing discomfort.
  • Durability: Gel Foam mattresses are known for their durability, ensuring long-term comfort.

Drawbacks of Gel Foam

  • Initial Firmness: Some users find Gel Foam mattresses to be initially firmer than expected.
  • Price: Gel Foam mattresses can be relatively more expensive than traditional mattresses.

Other Cooling Variations to Memory Foam Mattresses

Mattress manufacturers have developed various techniques to maintain a cool and comfortable sleeping experience with memory foam beds. Factors such as the gel foam mattress itself’s structural design, added materials, plant-based alternatives, and cover materials all promote coolness.

  • Mattress Structural Design: Certain mattresses feature convoluted air channels that enhance airflow and breathability. These channels can run vertically from top to bottom or be arranged in a zoned system to improve ventilation in areas with increased airflow.
  • Additives in the Mattress: The inclusion of additives such as graphite and copper, which are effective heat conductors, can contribute to the coolness of a mattress. These additives help disperse heat, allowing you to sleep comfortably throughout the night.
  • Plant-Based Substitutes: Replacing traditional petroleum-based materials with plant-based oils results in a more breathable and responsive memory foam. This helps maintain a cool sleeping environment, as plant-based oils are cooler than their synthetic petrochemical counterparts.
  • Cover Material: High-quality mattresses may feature innovative cover materials, such as FDA-approved Celliant® fabric, which can convert body heat into energy. This innovative cover material can contribute to a cooler night’s sleep by helping to regulate temperature.

Memory foam and gel memory foam are popular materials used in mattresses, mattress toppers, and pillows. They both offer unique properties for comfort and support, but they have some key differences. Here’s a breakdown of their similarities and differences:


  • These mattresses come in various firmness options, catering to the needs of side sleepers, back sleepers, stomach sleepers, and those who shift positions during the night.
  • They conform to your body’s shape, relieving pressure points and reducing discomfort.
  • For individuals dealing with back pain, these mattresses are beneficial. The memory foam material molds to your body, supporting the natural curvature of your spine, thereby enhancing lumbar support. This improved support can alleviate lower back pain.
  • Both types of mattresses may initially emit an off-gassing odor, which results from releasing volatile organic compounds (VOCs) at room temperature. Allowing them to air out for 3 to 7 days effectively eliminates this odor.
  • Couples can also appreciate these mattresses as they help minimize motion transfer.


  • Gel memory foam provides a cooler sleeping experience compared to conventional memory foam.
  • Incorporating gel into these foam beds can make them feel slightly more responsive compared to traditional memory foam mattresses.

Other Mattress Types

If memory foam or gel memory foam mattresses aren’t suitable for your sleep preferences, there are various other mattress types available in today’s market. Depending on your preferences and requirements, you can consider the following options:

Latex Mattress

Latex mattresses are crafted from either natural latex derived from rubber tree sap or synthetic latex foam. Opting for natural latex is recommended, as synthetic latex tends to deteriorate more quickly, leading to sagging.

All-natural latex beds are an excellent choice for those seeking an organic mattress. Organic latex mattresses conform to your body, although not as closely as regular memory foam mattresses. Compared to memory foam, latex provides a bit more bounce and naturally regulates temperature, offering a cooler sleeping experience.

Traditional Innerspring Mattress

Innerspring mattresses are the most common type of mattress and are available at a wide range of prices. They typically consist of a thin comfort layer made from materials like cotton, wool, or poly-foam and a coil layer at the base. The coils in these mattresses promote airflow, making them cooler than traditional memory foam mattresses. However, they can also transfer motion, potentially leading to sleep disturbances when one partner moves.

Hybrid Mattress

Hybrid mattresses combine the characteristics of innerspring beds with those of latex or memory foam mattresses. These hybrids usually feature a pocket-coil layer as the base of the foam bed, topped with a comfort layer that is more than 2 inches thick. The comfort layer conforms to your body, alleviating pressure points, while the base layer introduces a slight springiness to your mattress.

Differences Between Memory Foam and Gel Foam

While the gel foam beds and memory foam mattresses share many similarities, three key factors set them apart:

Temperature Regulation

Gel foam mattresses provide a cooler sleeping experience than memory foam mattresses. This is achieved by using a top layer containing cooling gel designed to dissipate heat and moisture without cooling the mattress. If you sleep hot, gel foam mattresses can offer cool-to-the-touch comfort.

Conversely, due to their closed-cell structure, traditional memory foam mattresses can trap heat, resulting in new mattresses with a warmer and cozier feel. Sleepers who get cold at night might prefer the warmth of a traditional memory foam mattress. Some may choose an open-cell memory foam mattress, allowing heat to escape.

Bounce and Resilience

Gel foam mattresses recover their original shape more quickly than memory foam mattresses. This is due to the gel pods incorporated into the top layer of gel mattresses, which provide a bouncy feel that conforms to your body and reverts to its original shape when you leave the bed.

In contrast, traditional and open-cell memory foam mattresses retain their shape for a slightly extended period. If you opt for a regular memory foam mattress, it’s advisable to rotate it every six to 12 months to ensure the foam cells regain their resilience.

Price Considerations

Gel foam mattresses are generally priced higher than regular memory foam mattresses because they involve more materials. For some individuals, gel foam mattresses’ enhanced cooling and bounce properties justify the slightly higher cost. However, budget-conscious sleepers may find that traditional memory foam mattresses offer ample comfort without straining their finances.
