An extra-deep mattress is the epitome of relaxation and restful sleep. Consider the height of the mattress when shopping for a new one to get a better idea of how comfortable it may be; after all, everyone dreams of sleeping every night in a five-star hotel.

Sleeping on a mattress that is too thin or too thick can affect your quality of life and even your health. The height or depth of a mattress is the same thing. Mattresses that are more than 16 inches in height are commonly referred to as "extra deep" or "extra tall."

Beds can vary in height depending on the size of the person sleeping on them and the thickness of the mattress they use. Your mattress's top should be 25 inches from the floor. If you sit on the edge of the bed, your feet will be able to reach the floor, making it much easier to get in and out of bed.

This article will go over some of the factors that go into determining the thickness of a mattress, as well as some things to keep in mind when shopping for a new bed of your own.

Statistics on Mattress Density

The depth of a mattress is not governed by any established norms. Standard mattress thickness ranges from 8 to 14 inches. The categories below will give you an idea of how mattresses are arranged according to their depth.

  • Thin mattresses, measuring 2 to 5 inches in height
  • 5-8 inch thickness: compact mattresses
  • Mattresses typically range in thickness from 8 to 12 inches.
  • Mattresses that are 12-16 inches in height are considered to be thick, deep, or tall.
  • Mattresses with a depth, width, or height of more than 16 inches

The first two bullet points refer to "thin mattresses," but it's important to distinguish between low profile and slim mattresses.

Mattresses with a low profile are typically air mattresses, or they can be found in cribs and fold-away beds. A toddler bed with a low-profile mattress is a good option, and these beds can also be used in guest rooms for short-term guests. (Since these beds are usually not suitable for adults and they tend to fall apart quickly, we wouldn't recommend them to people who frequently host out-of-town guests.)

Thin mattresses are more comfortable and long-lasting because they are made of multiple layers of foam. These mattresses are great for adults and are especially helpful for people with mobility issues who want to avoid sleeping on thick mattresses.

The Determinants of Mattress Depth

Each of a mattress's layers contributes to its overall height. The typical mattress has 2 layers, but higher-end ones may have 3, 4, or even more. Various substances are found in each successive layer. Your mattress's comfort, structural integrity, and longevity are all impacted by the materials used to make it. Every mattress has two primary layers: the comfort layer and the base layer.

Supple Thickening

The soft, top layer of a mattress is called the comfort layer. The comfort layer of an innerspring mattress, for example, is typically a pillow top made of cotton, wool, or poly-foam. A mattress with a pillow top has an extra layer of fluffy fabric sewn and stuffed into the cover for added comfort.

In contrast, the comfort layers of latex, hybrid, and memory foam mattresses are made of either of these materials. The substances used in their foundations vary. The top comfort layer of a mattress determines its contouring and pressure relieving capabilities.

It is recommended that comfort layers be between 2 and 3 inches in thickness. For extra coziness, some mattresses have multiple layers of foam, wool, or memory foam; others have built-in fans or a special coil system to provide specialized support for the spine; still others use electromagnetic fields to induce a state of

It's common practice to refer to the layers immediately below the comfort layer as "transition layers." The transition layers in some mattresses are designed to provide extra support for specific areas of the body, such as the neck, shoulders, back, hips, and feet. Your shoulders and hips need a softer cushion while your head, back, and feet require firmer support.

Base Layer

Mattress longevity is determined by the quality of the base layer, also known as the foundation layer. The mattress base should account for at least half of the total thickness in a high-quality mattress. If you're looking at a 12-inch mattress, for instance, make sure the foundation layer is at least 6 inches in depth. When it comes to mattress longevity, a thicker base layer is typically preferable.

The coils that make up the foundation of innerspring and hybrid mattresses are the most common type of mattress support system. Latex mattresses typically have a polyfoam base, while memory foam mattresses typically have a latex foam base.

Questions to Ask When Choosing a Mattress Depth

The recommended minimum thickness for a long-lasting and comfortable mattress is 8 inches, which should include a 2 to 3-inch thick comfort layer and a 5 to 6-inch thick base layer.

Generally speaking, the softer a mattress is, the thicker it is. The factors that should be taken into account when choosing a mattress thickness are discussed below.

Body Position While Sleeping

No matter what sleeping position you prefer, the thickness of your mattress has an effect on how well you sleep. Different sleeping positions call for different amounts of support and cushioning. Different thicknesses of mattresses can meet these individualized requirements for rest.

  • Mattresses that are 12 to 14 inches thick and provide ample support for the hips and shoulders are ideal for side sleepers. When you sleep on your side, your entire weight is distributed across these areas. The soft comfort layers offer the necessary padding to prevent soreness in the hips and shoulders.
  • Mattresses that are 10 to 12 inches thick are ideal for back sleepers because they conform to the body's natural curves, reducing the risk of spinal misalignment. Backache, neck pain, and muscle stiffness are all symptoms of spinal misalignment. You won't have to worry about your back sinking into a mattress that's only 10 to 12 inches in height thanks to the thick base layer and thin comfort layer.
  • If you sleep on your stomach, you should have a mattress that is at least 10 inches thick to minimize the risk of spinal misalignment. A thinner comfort layer means a firmer mattress, which means less pressure on your stomach while you sleep.
  • People who sleep in a variety of positions throughout the night are said to be combination sleepers. Combo sleepers require a mattress that strikes a good balance between firmness and softness because they shift positions frequently throughout the night.

Body Type

How your mattress reacts to your weight depends on its thickness and the materials it's made from. To get a good night's sleep, you need a mattress that provides adequate support, and this is in part determined by your weight.

  • Those who weigh less than 130 pounds per square inch when sleeping should look into mattresses that are 12 inches in height or more. The deeper padding contours to their shape, easing soreness and pressure everywhere it touches.
  • Weighting in at an average of 130 to 230 pounds, the average sleeper has their pick of mattresses ranging in thickness from 10 to 12 inches. If you're in the market for a thick mattress, it's important to research the materials used in each layer. On a medium bed, most people will find a good night's sleep.
  • Mattresses between 12 and 14 inches in thickness, with a comfort layer of at least 6 inches thick, are available to plus-size sleepers (those weighing more than 230 pounds). When the mattress's comfort layer is thick enough and has enough give, it can prevent sinkage.

How You Sleep (Solo or With a Partner)

When compared to a thin mattress, a thick one with multiple layers and a substantial base layer may provide more comfort and support. It's harder on a mattress when you have a bedmate than when you sleep solo. A sagging mattress is often the result of extra weight on a thin mattress. A mattress of at least 10 to 12 inches in thickness is recommended.

Conditions Unique to Medicine

Mattresses with thinner comfort layers and a firmer support core may be appropriate for people with medical conditions like back pain. Mattresses between 8 and 12 inches in thickness, with a medium-firm feel, are recommended for people who suffer from back pain. These mattresses are well-balanced in terms of firmness; they provide adequate support to avoid sinkage and prevent back pain, but they are also pliable enough to follow the shape of your spine. Back pain can be alleviated by selecting a back support that contours to your spine's natural curvature.

Arthritic, shoulder, and hip pain sufferers benefit from the extra cushioning provided by softer mattresses. Individuals in this predicament may benefit from a mattress thickness between 12 and 14 inches. For one thing, the thicker the mattress, the more likely it is to have comfort layers that are thick enough to conform to your body and relieve pressure on your hips, shoulders, and knees.

How High Your Bed's Frame Is

Take into account the height of your box spring, foundation, platform, or adjustable bed when selecting a mattress depth. You shouldn't have a bed that's higher than 25 inches, which includes the frame and the mattress.

If your mattress is 18 inches thick, your bed's foundation shouldn't be more than 7 inches high. Beds that are too high may make it difficult for people with mobility issues like back pain, joint pain, or arthritis to get in and out of bed.

The Pros and Cons of Extra-Thick Beds

The hips, shoulders, and other trouble spots can all find relief on thick mattresses because they are typically softer than thin beds. On the other hand, thick mattresses can be more expensive and cumbersome to move around. Think about the thickness of each layer and how it will affect the overall feel of the mattress when shopping for a new one.


  • Extra padding makes them a good choice for those who prefer to sleep on their sides.
  • It's safer to sleep with a partner on a thicker mattress, as thinner ones can sag under the weight of two adults.


  • Having more materials and layers means a higher price tag.
  • Due to the increased number of layers, this mattress is more cumbersome to move or lift when it needs to be made.
  • People with mobility issues may have trouble getting in and out of thicker beds because of their height.


At what depth does one typically find a mattress?

Most mattresses are between 8 and 14 inches in height. A good mattress will have a comfort layer of at least 2 to 3 inches and a support core of 6 to 8 inches. A 1-2 inch thick transition layer is also present in the majority of mattresses. This thickness is the bare minimum required for acceptable comfort and longevity.

Would a more plush mattress be preferable?

The most comfortable and supportive mattresses have a thickness of at least ten inches. A mattress that is 12 to 14 inches thick is likely to provide the optimal amount of support for those who sleep on their sides. Most people who sleep on their backs prefer mattresses that are 10 to 12 inches thick and medium-firm, while those who sleep on their stomachs may need a mattress that is at least 10 inches thick and firm enough to prevent sinkage beneath the abdomen. Stomach sleeping is not advised because it can lead to back pain from spinal misalignment.

Is it true that the base layer of a mattress has an effect on its longevity?

There is a correlation between the thickness of the foundation layer and the lifespan of a mattress. Long-lasting mattresses typically last between 8 and 10 years. This is especially true of those made with high-quality base foams or sturdy pocket coils. Make sure the foundation of your bed takes up at least half the total height of the mattress.

Which memory foam mattress thickness is ideal?

Body-contouring support can be found in mattresses with a thickness of 10 to 14 inches of high-quality memory foam. They are long-lasting, with a ten- to fifteen-year lifespan. Mattresses with a memory foam layer any thinner than this may not be sturdy enough to prevent the onset of sagging and soft spots within the first three to four years.

How about a 2-inch topping?

The typical thickness of a mattress topper is between 2 and 4 inches. You can get a softer or firmer mattress set by adjusting the fillings. A 2-inch thick topper should be sufficient if you only want to slightly alter the feel of your bed. First, determine whether you prefer a soft or firm topper, and then make your purchase decision.


It's a hassle to get in and out of bed if the mattress is too thick, but it might not be supportive enough for a good night's sleep if it's too thin. In order to find a happy medium between being too thick and too thin, most people recommend a mattress that is 10 to 14 inches in thickness. To get the most out of your purchase, look for a mattress that is between 10 and 14 inches in thickness, depending on your preferences and the mattress' construction materials.
