Everyone wants a comfortable sleep at night and everyone associates a thick mattress with luxury and comfort. So how does one choose the thick mattress? The height of a mattress gives you a better sense of how comfortable your mattress is. But the thickness of the mattress affects your comfort level. Sleeping on a mattress that is too thick or too thin can easily impact your sleep and your health as a whole.

The thickness of the mattress also affects the height of the bed. Ideally, the top of the mattress should be 25 inches from the floor. This way you can easily reach the floor while you are seated at the edge of the bed, making it easy to get in and out of the bed. The standard mattress thickness is between 6-9 inches. But some luxurious mattresses are 12 inches thick and another mattress that goes beyond luxury measures at an astonishing 16-18 inches.

Besides all the "grandiose" ways to choose your mattress and how thick a mattress do you need is something that this article would try to answer.

What Constitutes a Mattress?

The mattress depth depends on the thickness of the mattress. Most mattresses have 2 layers within them, but a high-quality mattress might have more layers. Each layer consists of different layers. The two basic layers are the base layer and comfort layer.

Comfort layers:- It is the plush layer on top of the mattress that comprises cotton, wool, or polyfoam. This layer is meant to provide the basic comfort layer to its sleepers. The thickness of this layer depends on the materials that constitute this layer.

Base layer:-This is the foundation layer that determines the durability of the mattress. It is almost 50% of the total mattress thickness. The thickness of a coil also determines the thickness of the base in Innerspring and hybrid mattresses.

·         Bodyweight

·         Sleeping positions

·         Health and medical conditions

·         High preferences

·         Mobility issues

Below we have mentioned in brief all the factors that are mentioned above and how they impact the comfort level of your mattress and impacts your buying decisions

Bodyweight and Type

The thickness of the mattress and the materials that are used to make the mattress depends a lot on your body weight and body type

  • Lightweight Sleepers(weighing less than 130 pounds):-Mattresses with a thickness of 12 inches and taller are a good option for people with lighter weight. The thicker comfort layers match their body, thus relieving the points of pressure and reduces aches.

  • Average Sleepers(weighing between 130 to 230 pounds):- Average size sleepers choose between 10 to 12 inches thick mattress, depending on their sleeping position. Medium beds are best suited for average sleepers.

  • Plus Size Sleepers(weighing above 230 pounds):-If you are a plus-size sleeper a mattress thickness between 12 to 14 inches thick mattress with a comfort layer of at least 6 inches is ideal for plus size sleepers.

Sleeping Positions

Different sleeping positions require different mattress thickness

  • Back Sleepers:-Back sleepers require support from their shoulders and buttocks. Back sleepers require a six to eight inches mattress. Back sleepers will also require a little “give” that will allow the small of your back to receive support to sink into the mattress. This will help to keep the spine in alignment.

  • Side Sleepers:-Slide sleepers require support for their shoulders and hips. A mattress with a thickness of 8-10 inches will be ideal for side sleepers. A solid foam slab with a solid foam core and a softer outside foam is ideal for side sleepers

  • Stomach Sleepers:- A mattress thickness of 10 inches to 15 inches with more comfort and less support is required for stomach sleepers. Memory foam mattresses are ideal for stomach sleepers.

  • Pregnant Women:-For pregnant women from mid-to-late pregnancy a soft top of four to six inches of soft memory foam that sits on top of a four-to-six inches medium-hard latex foam base is considered ideal. It provides excellent comfort and support.

Health and Medical Conditions:-

People with health issues will require a firmer mattress with thinner layers of comfort. Mattress with 8-12 inches of medium-firm thickness is considered good for back pain and suffering. These beds are firm to support your back and prevent your mattress from shrinking while being so soft that they would support the natural curvature of your spine thus relieving you from backaches.

A thin heated water-filled mattress provides an even and gentle warmth that penetrates and relaxes your muscles allowing a more restful and therapeutic sleep. Waterbeds contours to the exact weight and shape of your body providing total even support. People with arthritis, shoulder pain, or hip pain need a softer mattress for extra cushioning.

Height Preferences

People with limited mobility having back pain, joint pain, or arthritis will find it difficult to get out of taller beds thus the overall height of the bed including the bed base and mattress should not be more than 25 inches. That will be in the calculation of your foundation and the thickness of the mattress.

Mobility Concerns:-

People with limited or specific mobility issues would need specific mattresses and beds that aid in their mobility easily. Some people, for example, require a wheelchair and mobility scooter to move around their house therefore their mattress should be such that it allows them to transition easily back and forth without putting much strain on their legs or their mobility as a whole.


A mattress that is too thick makes mobility difficult while a too-thin mattress might not be supportive enough for a good sleep. An ideal mattress is 10 to 14 inches thick to be balanced.But depending on the material that the mattress is built it finally is your personal preference that makes you comfortable
