How to Select Thickness of a Mattress With Memory Foam

There are a few concepts that are important when considering memory foam material as part of your mattress purchase, and thickness is definitely on this list. How thick should mattresses with memory foam be, and which factors might influence your selection here?

At Sunset Bedding, we're proud to offer a huge range of mattresses with memory foam and numerous other mattress styles, including pillowtop twin, queen and king mattresses among many others. Our Delicate Arch line, for instance, features memory foam and several other forms of support foam, and many of our other mattresses incorporate memory foam and other foam types into their support structures. Here are some basics on how mattresses with memory foam work, the specific kinds of foam found in these, and some key factors in deciding on memory foam thickness for your new mattress.

Thickness of a Mattress With Memory Foam

Why Memory Foam

First, let's start with discussing why memory foam is such a popular choice for mattress materials. Memory foam was first developed by NASA in the 1970s as a material that could absorb and distribute pressure evenly throughout astronauts' bodies during takeoff. Now, it's become an integral part of many mattresses due to its unique ability to contour to your body's shape while providing support and relieving pressure points.

Types of Memory Foam

There are several types of memory foam used in mattresses, each with its own features and benefits:

  • Traditional memory foam: This is the most common type found in mattresses. It responds to heat and pressure,
    softening and molding to your body's shape. 
  • Gel-infused memory foam: This type of memory foam contains gel beads that help regulate temperature and prevent
    overheating.
  • Plant-based memory foam: This eco-friendly option is made from renewable plant materials, making it a more
    sustainable choice.

Support Foam

There are also a few different forms of lumbar support foam, and these will generally work in concert with the memory foam to create a balanced, supportive surface. There are also several different types of polyurethane foam that may be used in various layers.

In most cases, your mattress will have at least one layer of high-density support foam, which is typically made from polyurethane. This is followed by a layer of transition foam or convoluted foam, which serves as a buffer between the memory foam and the support layer.

Generally speaking, these combined layers can range from six inches on the thinner end up to over a foot on the thicker end. Our next few sections will go over some of these options and how to think about them.

Thickness Ranges

While this can vary somewhat between specific mattresses and needs, here are some general thickness ranges for memory foam and related foam packets:

  • 6-8 inches: This is the thinner range, generally used for lighter individuals and those who prefer a softer mattress surface. This thickness may also be suitable for children's mattresses or guest rooms.
  • 10-12 inches: The medium range, this is the most common thickness level for mattresses with memory foam. It offers a good balance between support and comfort for most sleepers.
  • 14+ inches: On the thicker end of things, these are generally best for heavier individuals or those with specific back issues that require extra support. Mattresses in this range can also offer additional cooling capabilities through more airflow.

Factors to Consider

When selecting your memory foam thickness, there are a few factors that may influence your thinking:

  • Your weight and height: Naturally, heavier individuals will need thicker mattresses to support their weight. Some taller people may also require more support. If you have specific physical needs or preferences, make sure to take these into account.
  • Sleeping position: Side sleepers often prefer thinner mattresses, while back and stomach sleepers may need thicker ones for proper spinal alignment.
  • Climate: As mentioned above, thicker mattresses tend to have better airflow. If you live in a warmer climate, this may be important in your decision-making process.
  • Personal taste: Ultimately, the thickness of your mattress is largely up to personal preference. Take the time to try out different options and see what feels best for you.
  • Back pain or related issues: If you suffer from chronic back pain or other issues, speak to your doctor about the best thickness for your specific needs.
