10 Inch vs 12 Inch Mattresses: Which One Should You Choose

Mattress thickness is essential for your sleep quality and overall well-being. However, getting overwhelmed by the different kinds of mattresses you see in a store is easy. In addition to the various sizes, materials, and softness, you also have to choose between mattresses of varied thicknesses.

Among the various kinds of mattresses you see in the store, the two most common types are the 10-inch and 12-inch mattresses. As you can see, there is a 2-inch difference.

Although 2 inches may not seem much, it can be a lot for a mattress. A mattress takes a lot of surface area, and adding two inches of thickness to it means the weight of the mattress is going to increase as well, along with its springiness.

Both these mattresses have their pros and cons. And almost all brands have mattresses of both thicknesses. If you are unsure which one suits you well or find differences between the brands, you may ask the representatives.

However, some points can help you understand their salient features and help you make a more informed decision.

Standard Categorization of Mattresses

Standard Categorization of Mattresses

Here is a standard categorization of mattresses based on their thickness.

1. Low Profile Mattresses

Low profile mattresses are specially designed mattresses that have a reduced height compared to standard mattresses. Typically, these mattresses have a thickness ranging from 5 to 8 inches, making them significantly thinner than traditional mattresses, which usually range from 10 to 14 inches in thickness.

2. Slim Mattresses

Slim Mattresses

These mattresses are five to seven inches thick. These offer moderate support but are still not suitable for everyone. They are also prone to sagging within some months of use. They are ideal if you do not want to make a long-term investment in mattresses in case you relocate.

3. Standard Mattresses

Standard mattresses refer to the commonly available and widely used mattresses that are designed to provide comfort and support during sleep. These mattresses typically feature a combination of materials such as coils, foam, or latex, encased in a fabric cover. They come in various sizes, including twin, full, queen, and king, to fit different bed frames and accommodate individual sleep preferences.

4. Tall and Extra Tall Mattresses

Tall and Extra Tall Mattresses

These specialized mattresses are designed to cater to individuals who require additional height and legroom while sleeping. With their increased height, these mattresses offer enhanced comfort and support, ensuring a more restful sleep for taller individuals or those who simply prefer a more spacious sleep surface.

What Makes a Mattress Thick?

The thickness of a mattress refers to its overall height or depth. It is determined by the number and thickness of its layers, which can include materials such as foam, springs, or other support systems. A thicker mattress often offers more cushioning and support, but personal preferences and specific sleep needs vary.

The thickness of the mattress is the result of its parts. It usually has two layers.

Comfort Layer

Comfort Layer

This is the top layer of the mattress. This layer is usually made of poly-foam, cotton, or wool in innerspring mattresses. Brands pay special attention to making this layer comfortable, and they are made with the softest fabrics.

Memory foam mattresses or hybrid mattresses have latex or memory foam comfort layers. How firm a mattress is going to be, or how comfortable it is, depends on the quality of this layer.

This layer is about fifteen to twenty percent of the total thickness of the mattress. Some beds may have two comfort layers for extra comfort. They are usually quite expensive.

Base Layer

The base layer forms the mattress’s foundation and determines its durability. Thicker mattresses have thicker base layers, making the mattress firm and preventing it from sagging.

The base layer can form up to fifty percent of the total thickness of the mattress. Innerspring mattresses have a base layer of coils, while memory foam and latex mattresses have poly and latex at the base.

Thicker mattresses, especially 12 inches and more, have transition layers in between. In high-end mattresses, buyers often customize these layers for specific support for the head, hips, or legs support. In addition, with the development of sleep technology, targeted back support or even cooling features of the mattress are also included in this layer.

Benefits of 10-Inch Mattresses

Benefits of 10-Inch Mattresses

Here is a quick overview of why you should consider a 10-inch mattress.

  • 10-inch mattresses are thick enough, and they do provide adequate support. However, the main reason for buying this mattress is that it is lighter and easier to move. It is also durable enough and won’t sag much if the person sleeping on it has a slim build.
  • It will offer greater support than other thicker mattresses because it is stiffer. Thicker mattresses may be softer because of more cushioning, but the 10-inch mattress will give you more support.
  • Those who love sleeping on their stomach occasionally will also find it more supportive as it keeps the spine straight even in this position.

Benefits of 12 Inch Mattresses

Here is a quick overview of why you should consider a 12-inch mattress.

  • The 12-inch mattress will support more body weight than other, thinner mattresses without sagging.
  • These mattresses offer more cushioning, and hence, they offer pressure relief. This is especially beneficial for those with more physical work as it will give them good relaxation.
  • 12-inch mattresses almost have a cradling effect, and those with heavier body weight will also find it very comfortable.

10″ vs 12″ Mattress: Factors to Consider for Your Decision

10 vs 12 Mattress Factors to Consider for Your Decision

Based on the points mentioned above, here are some points you should consider before you decide whether to opt for a 10 or a 12-inch mattress.

1. Body Weight

The higher the body weight, the more support it will need. 10-inch mattresses are firm but have less cushioning, but 12-inch mattresses have a thicker foundation layer. Hence, lightweight sleepers could feel comfortable in both.

However, those with heavier body weight should ideally go for the 12-inch mattress as it will provide better support and cushioning.

2. Sleeping Style

Sleeping Style

Both 10-inch and 12-inch mattresses are suitable for those sleeping on their backs. A thin comfort layer and a thicker base layer are best for better spine alignment.

However, those who sleep on their sides will find the 12-inch mattress more suitable as it is more comforting for the bones in the shoulders and hips. On the other hand, those who sleep more on their stomachs will find the 10-inch mattress more appropriate as it offers more support in that position.

3. Number of Sleepers

Since the mattress will carry more body weight, it is better to use a 12-inch mattress for a better sleeping experience.

If more than one person is sleeping on the mattress, both their preferences should be considered. If one partner rolls over during sleep, the other partner should not feel his/her movement.

4. Medical Condition

Medical Condition

Those with medical conditions or spinal issues must choose a mattress after consulting their doctor. Apart from the factors like cushioning or durability, the height of the bed should also be considered.

If the base of the bed is already high, then a thicker mattress should be avoided as it will raise the total height of the bed. That will make it difficult for older patients or those with mobility issues to get in and out of bed.


Here are some questions about mattresses, the answers to which can help you make a better decision.

Is a 10 Inch mattress a thick mattress?

Yes, a 10-inch mattress is a standard, thick mattress, and it is suitable for most sleepers. It is firm with a thinner comfort layer, but the base layer provides adequate spine support.

When to opt for a 12-inch mattress?

You should opt for a 12-inch mattress for predominantly two reasons. First, if you want lots of comfort and cushioning. Second, if you are heavyweight and need more support, a 12-inch mattress can give you because of a thicker base layer that won’t sag easily.

Will a 10-inch mattress last longer or a 12-inch one?

Both a 10-inch mattress and a 12-inch mattress can have similar lifespans if they are of good quality and properly maintained. The thickness of the mattress alone does not determine its durability or longevity. Other factors such as the materials used, construction, and overall quality play a more significant role in determining how long a mattress will last.

Is a thicker mattress better than a thinner one?

It depends on personal preference and specific needs. Some people find thicker mattresses more comfortable as they provide additional cushioning and support. Thinner mattresses can be suitable for individuals who prefer a firmer surface or have specific requirements for their sleeping arrangements. Ultimately, the “better” choice between a thicker and thinner mattress is subjective and varies from person to person.


At the end of the day, you look forward to a good night’s sleep. The right mattress can help you achieve that. Trying out a mattress and using the trial periods offered by most reputed brands is always a good idea.

While both the 10-inch and 12-inch mattresses have their advantages, you should also consider your personal preference. Please do not buy a mattress because your friend found one suitable for themselves, but rather go with how you felt while lying on it.
