How To Choose The Right Mattress Thickness?

The thickness of a mattress is an important factor that plays a major role in how well you sleep. While some people think a thick mattress means ultimate comfort and great sleep, it's not the same for everyone. How thick your mattress should be depends on things like how you sleep, how tall you are, if you share the bed – and so on.

Keep reading to learn more about mattress thickness and how to choose the right one for the best sleep.

What Contributes to Mattress Thickness?

The thickness of any mattress depends on its materials and layers. Let’s take a closer look at the different layers of mattresses. 

  • Comfort Layer

    The top layer of your mattress, known as the comfort layer, determines how hard or soft it feels overall. This layer supports your body's shape and helps relieve pressure on your joints. The top layers are usually made of materials like polyurethane foam, memory foam, latex foam, nano coils, gel, or wool, and they're typically 1 inch to 4 inches thick.

  • Base Layer

    The bottom layer, called the base layer, provides essential support and usually makes up about half of the mattress. It's often made of sturdy materials like foam, coils, or latex. This layer ensures your body stays properly aligned and prevents you from sinking too much into the softer layers.

  • Transitional Layer

    Several mattresses have a transition layer between the top and bottom layers. These are usually made of medium-density materials like latex or polyfoam and help transition between the mattress's support and softness.

Mattress Categories Based on Thickness Levels

Mattresses come in a variety of thicknesses, each offering unique advantages depending on your sleep style and needs. Let's delve into the common categories:

Mattress thickness chart

Here is a mattress thickness chart to get an idea about different mattress thickness ranges and which one is suitable for particular age groups and different types of sleepers.

  • Low profile mattress(2-4 inches):

    Low profile mattress is 2 to 4 inches in height. They are suitable for cribs, toddlers and guest beds.

  • Standard mattress( 5-8 inches):

    Standard mattress is 5 to 8 inches thick. They are suitable for most adults and offer a good level of comfort while sleeping. They are easily available and there are a wide variety of options available to choose from as per your budget and other individual preference.

  • Thick mattress (10 inches and above)

    Thick mattresses are 10 and above in height. They are suitable for side and heavy sleepers. They offer extra support and cushioning effects while sleeping. It is difficult to move. These mattresses are usually custom made.

Choosing the Right Mattress Thickness: Key Factors to Consider

  1. Sleeping Position

    • Stomach Sleepers

      If you prefer sleeping on your stomach, it's best to have a mattress that offers strong support to keep your body from sinking too much. This can help prevent back pain. A thinner, firmer mattress might be okay, but having a softer layer near the top can provide some relief for your chest and shoulders.

    • Back Sleepers

      Back sleepers also need a bed that offers firm support but with enough pressure relief to avoid straining the lower back. A mattress usually needs multiple layers to achieve this balanced support and comfort.

    • Side Sleepers

      For side sleepers, a thicker mattress with soft layers near the top is ideal. This allows the hips and shoulders to sink comfortably without hitting the firm base layer, which could lead to discomfort during sleep.

    • Combination Sleepers

      Combination sleepers usually feel comfortable on 8 or 10-inch-thick mattresses that are kind of in the middle - not too soft or too hard. Since they switch between sleeping on their side, back, or stomach during the night, they need a mattress that's just right making 8 or 10-inch thick mattresses an ideal choice.

  2. Body Type

    • Lightweight Individuals:

      For lighter individuals, a mattress thickness of 8 to 10 inches is ideal, but a thickness of 4-6 inches is also sufficient. This thickness provides adequate support without feeling overly firm.

    • Average Weight Individuals:

      Individuals with average weight can opt for a mattress thickness ranging from 10 to 12 inches. This thickness offers a balance of support and cushioning, promoting a comfortable sleep experience.

    • Heavyweight Individuals:

      Heavier individuals benefit from thicker mattresses, typically ranging from 12 to 14 inches or more. A thicker mattress provides enhanced support and durability, reducing the risk of sinking and promoting proper spinal alignment.

  3. Height of Your Bed Base

    Consider the total height of your bed base, including the mattress, when deciding on the thickness of your mattress. Ensure that the combined height does not surpass 22 inches (from the floor) to maintain ease of access in and out of bed.

  4. Material Composition

    Different types of mattresses need different thickness levels to work best. Memory foam mattresses usually need to be medium to thick, while latex ones can be a bit thinner and still do a good job. Hybrid mattresses, which have springs inside, are usually thicker, especially if they have a fancy top layer.

    The density of memory foam also matters. Denser foam tends to make a mattress last longer compared to thicker mattresses with less dense foam.

  5. Number of People Sharing the Bed

    If you share your bed with others like a partner or pets, you need a thicker mattress to support the extra weight. A bed that's 8 -10 inches thick should be sturdy enough to keep from sagging and support everyone sleeping on it.

  6. Medical Conditions

    If you feel pain at night or have certain health issues, picking the right mattress thickness can make you feel better.

    If you have arthritis or sore joints like in your shoulders or hips, a softer mattress could be best. It helps take off pressure from those sore spots by spreading your weight across the bed. A mattress that's 10 to 14 inches tall is great.

    For back pain, aim for a mattress that's about eight to 12 inches thick. A thinner one might not give enough support for your body's curves, possibly causing more pain. But a super thick mattress might be too soft and make you sink in too much, not supporting your back well.

    If you have trouble moving around, go for a thinner mattress. Pick one that gives just enough support and comfort. Thinner beds are easier to move on, more stable, and don't have as many layers to get stuck in.

  7. Age

    For little kids, a thinner mattress is safer because it's not as high, so they're less likely to fall off. Since kids are small and light, they don't need a super thick mattress to feel comfy or supported. And if you're getting a bed for an older person, a firm mattress like an orthopedic mattress is the right choice.

Closing Thoughts

Your mattress thickness is more than just a number; it's the key to a restful night's sleep. By understanding your unique sleep needs and considering factors like sleeping position, body type, and medical conditions, you can find the perfect mattress thickness for optimal comfort and support. With the right mattress, every night can be a dream come true!


  1. Are thicker mattresses better?

    Yes, generally thicker mattresses are better. However, the ideal thickness depends on factors such as the combined height of the bed and mattress (shouldn't exceed 22 inches), as well as the weight of the sleepers. A 6-inch thickness is suitable for individuals or couples weighing less than 90 kilograms, while 8 or 10 inches is recommended for those weighing more.


  2. Does mattress thickness affect sheets?

    Yes, the thickness of your mattress can change what kind of sheets you need. If you have a thick mattress, you might need deep pocket sheets. These are designed to fit taller mattresses. Check the packaging to see what depth the sheets are made for.

  3. Does thickness affect how long a mattress lasts?

    Yes, thicker mattresses can last longer. The thicker the support layer, the less likely it is to sag. A good mattress with quality materials can last up to 10 years. Thinner mattresses might not hold up as well over time, depending on the quality of materials and the mattress’s build technology and design.
