What Is the Difference Between Memory Foam and Latex?

Choosing which type of mattress is the best mattress for you can be difficult, especially since there are so many options available. Memory foam and latex are two popular materials, and each offers unique pros and cons.

Memory foam mattresses typically offer close-conforming pressure relief and excellent motion isolation. On the other hand, latex tends to be bouncy, durable, and breathable.

Knowing the differences between the two materials can help you make an informed decision when choosing a mattress. We’ll cover their compositions, potential benefits and drawbacks, and which sleepers may benefit from each material.

What Is Memory Foam?

Memory foam, or viscoelastic polyurethane foam, is a popular synthetic material. It was originally developed in 1966 through research funded by NASA to create a shock-absorbing material for airplane seats. It is a type of polyurethane with additional chemicals that make it denser and more viscous. These qualities help memory foam absorb a significant amount of movement while responding slowly to changes in pressure.

Memory foam softens in response to a sleeper’s body heat, causing it to mold to their shape. Close contouring redistributes the sleeper’s weight to limit pressure buildup and support the spine.

Breakdown of Memory Foam

Description Pros Cons
Memory Foam Memory foam is a close-conforming synthetic material that hugs the body in response to its warmth.
  • Excellent pressure relief
  • Strong motion isolation to reduce sleep disruptions
  • Widely available
  • May retain body heat
  • Can impede movement
  • Prone to off-gassing

Who Should Sleep on a Memory Foam Mattress?

Sleepers who enjoy a hugging sensation or prioritize motion isolation may prefer a memory foam mattress. Memory foam can ease pressure since it contours closely to the body, so it may also be appropriate for those with aches and pains.

Memory Foam
Pros Cons
  • Can help relieve joint pain and pressure points
  • Typically provides good spinal support
  • Limits motion transfer
  • Often traps heat
  • May not provide adequate support for sleepers over 230 pounds
  • Can contribute to a sensation of being trapped in the bed

What Is Latex?

Most latex mattresses use natural latex, though synthetic and blended options are also available. Natural latex consists of sap from rubber trees that’s processed into foam-like material. Synthetic latex uses petrochemicals instead of rubber-tree extract, while blended options contain a mixture of natural and synthetic components.

Latex mattresses typically have a slightly springy feel with moderate contouring. This responsiveness and limited sinkage make it easier to change positions and get in and out of bed. The material has an open-cell structure and is frequently aerated with small holes, allowing heat to dissipate.

Compared to memory foam mattresses, latex models tend to be fairly expensive. However, they are also generally more durable, so you shouldn’t have to replace them as often.

Description Pros Cons
Latex Latex can be natural, synthetic, or blended. It typically provides good temperature neutrality, moderate contouring, and a responsive feel.
  • Springy feel for easy movement
  • Good temperature regulation
  • Highly supportive and durable
  • Natural latex uses renewable materials
  • Usually relatively expensive
  • Generally provides less motion isolation than memory foam
  • Typically heavy and difficult to move

Who Should Sleep on a Latex Mattress?

Latex mattresses spread the compression over a wider area than memory foam, making them appropriate for many individuals over 230 pounds, stomach sleepers, and others who need extra support. Those who tend to sleep hot may prefer latex mattresses due to the material’s breathability. Eco-conscious shoppers also frequently favor natural latex mattresses because they typically use more sustainable materials than other models.

Latex
Pros Cons
  • Exceptional support
  • Very good temperature regulation
  • Typically quite durable
  • Limited motion isolation compared with memory foam
  • Less contouring than memory foam
  • Generally more expensive

How Do the Two Match Up?

Memory foam and latex are both exceptionally comfortable for certain sleepers. However, each performs differently, appealing to distinct groups. Individual models vary in their performance, but understanding the general qualities of memory foam and latex can help you narrow your mattress search.

Memory foam contours to the body, relieving pressure and limiting motion transfer. However, this close hug can also trap heat. Latex conforms less closely, giving it a more supportive feel and greater breathability. Mattresses made of latex are also usually highly durable and have minimal off-gassing odors. That said, latex models tend to absorb less motion and cost more.

Memory Foam vs. Latex

Category Memory Foam Latex
Price Memory foam mattresses are usually less expensive than latex models but more expensive than polyfoam. Since most latex is naturally derived, it’s typically significantly more expensive than memory foam. On average, you can expect to pay twice as much for a latex model.
Support Memory foam mattresses conform to a sleeper’s body, which is frequently beneficial for spinal support. However, they tend to sag as they age, reducing the support. Because latex models limit sinkage, they are often supportive enough for stomach sleepers and individuals over 230 pounds. Latex also offers exceptional long-term support, retaining its shape throughout the mattress’ lifespan.
Durability Memory foam mattresses usually last 6 to 7 years. Higher-density memory foam is more durable and less prone to sagging than lower-density options. Latex mattresses are generally more durable, lasting an average of 7.5 to 8.5 years. They also typically have longer warranty periods than memory foam models.
Temperature Neutrality Traditional memory foam tends to retain body heat. Some memory foam mattresses now incorporate technology intended to reduce this tendency, such as gel infusions. Latex offers good temperature regulation since it has an open-cell structure and doesn’t contour as closely to the body. Some latex models are aerated for additional airflow.
Feel & Performance Memory foam conforms closely to your body and regains its shape slowly when you change positions, letting sleepers sink deeply into the top layer of the mattress. Latex contours with less hug and more buoyancy, which limits sinkage and provides a bouncier, more supportive feel.
