How Thick Is A Standard Mattress

How Thick Is A Standard Mattress

The thickness of a mattress is perhaps the most important aspect to consider when you purchase one. The proper thickness will give you the support your upper and lower back need while lying down and keep your spine aligned with proper posture.

How Thick Is A Standard Mattress

The standard mattress has 8 to 12-inch thickness. You should choose a bed depending on your sleeping position and other factors. For example, if you are a side sleeper or sleep on your stomach, it is essential to buy a thicker mattress because it will provide more support for the back and hips. Continue reading, and you’ll get all the necessary information about what to consider thinking on mattress thickness before purchasing.

Benefits Of Thick Mattress

Thicker mattresses are often more comfortable than lighter ones. They provide better support for all parts of the back, including hips, shoulders, and head.

Thick mattresses also offer more versatility to sleep on without restricting your body movement. To add a layer of comfort, consider adding a mattress topper or pillow top. A thick mattress tends to last longer than a thinner one.

Benefits Of Thin Mattress

There are several reasons why a thinner mattress is recommended. They are:

  • You may feel hotter or colder than what you should be feeling.
  • A thin mattress is usually lighter in weight and can be easily moved around.

This may also help with airflow and cooling when you sleep. You may be more likely to roll onto your side as well which is considered healthier than sleeping on your stomach (too much pressure on the hips).

Mattress Thickness Chart

Mattresses generally are made of foam, cotton, wool, latex, or other composite materials for comfort. They are divided into layers that determine their thickness as well as performance properties during your sleep. 

Below, there’s a mattress thickness chart for consideration.

Factors Determining Mattress Thickness

Many factors determine the thickness of a mattress. The most important include the comfort layer, the type of material used in its construction, and the density of foam in the top and bottom layers.

Mattress Type

Not all mattresses are made the same way. They are built for different purposes, as well as levels of comfort, firmness, and support. Some beds are built to be thick, while others are recommended to be thinner. 

Examples of some standard mattress types include:

  • Innerspring Mattress. An innerspring mattress is one of the most popular types available on the market. It is made from coils and padding surrounding them. The thickness greatly depends on the number of coils used in its construction. Mattress measurements may vary among manufacturers, but as an average, innerspring mattresses fall between 7″ and 20″ thick.
  • Air Mattress. An air mattress is made with thin vinyl that inflates to provide comfort while you sleep. There are no springs in an air mattress, which explains why it is very light and portable. It can give firm support to all parts of the back or even uneven areas of your body. The average air mattress will be about 8 inches thick.
  • Memory Foam Mattress. Memory foam is a specialty type of mattress material, which is made from polyurethane foam. It is a memory foam type that adapts to the contours of your body, providing support and comfort for many hours without having to be replaced. Memory foam mattresses are generally pretty thick, measuring 12-15 inches.
  • Hybrid mattress. A hybrid mattress type is a combination of two or more materials. This material type provides a good balance between comfort and support. The thicker it is, the better the body support from the mattress. An example of a hybrid would be innerspring over padding/memory foam construction with varying degrees of thickness.

Comfort Layer

The top layer of most mattresses is made of a thin foam layer to add comfort for the person sleeping on it. It is also used to absorb and disperse heat. The density of foam determines how thick the top layer of the pillow top or mattress topper should be.

Base Layer

The base layer in most mattresses is made of a dense material that supports the entire bed when compressed or expanded during your sleep. The thicknesses are usually about 2-4 inches, making it possible to move around without losing your balance or causing damage to your bed.

What To Consider When Deciding On Mattress Thickness

There are many important considerations when purchasing a mattress, including the above factors that determine its thickness. Your needs, budget, and sleeping position are primary factors to consider when choosing the right thickness for your bed. Depending on your sleeping position, you may need a thicker or thinner mattress than the one recommended above.

Sleeping Position

The different positions you choose to sleep in are:

  • Side sleeper – The mattress should be at least 8 inches thick for side sleepers.
  • Back sleeper – The mattress should be at least 15 inches thick for back sleepers.
  • Stomach sleeper – A thin 8-10 inch mattress works fine for stomach sleepers.

Body Type

Your body type is another important aspect that determines your bed’s thickness. You should consider this a factor before buying a mattress since it will determine how much support the mattress should have to prevent back pain in the long run. 

There are different types of body types:

  • Thin people – If you are skinny with little muscle development, it is best to buy a thin mattress so you can enjoy a comfortable sleep without having your back and hips ache for many years.
  • Normal people – Most people fall into this category, which means the thickness of your bed may not be as critical as other factors to consider.
  • Heavy people – If you are overweight, it is best to buy a thicker bed for support and comfort as you sleep.
  • Tall people – If you are tall, consider buying a thicker mattress than the recommended above for better support.

Mattress Durability

It is also very important to consider the durability of your mattress before making a purchase. A thicker mattress will be more durable since it will have more layers of material and fewer coils in its construction.

A bed with good durability will last many years before requiring replacement. With this in mind, the thickness of your mattress should depend on how long you intend to keep it before replacing it, as well as its purpose.
