How Thick Should Your Mattress Be?

One of the things that we love about hotel mattresses is the comfy and surreal feeling of sinking into the soft and thick mattress. Thick mattresses look extremely luxurious and comfortable. Not to mention, they are more durable than thinner sleep solutions. Everyone wants luxurious sleep, but no matter how promising thick mattresses are, we don’t need an all-too-thick bed that is too hard to get in and out of. There are various factors to consider when choosing the right mattress height.

The appropriate mattress thickness should be determined by your needs and comfort preferences. A mattress that is too thin may not provide the best support and may sag prematurely. On the other hand, a mattress that is too tall or thick may not be beneficial for people with mobility issues. The best mattress height will support your body’s comfort needs while making it convenient to get in and out of your bed.

When buying a new mattress in Singapore, there are a few things to consider, like your sleeping position, body type, and comfort preferences. These factors are also crucial in choosing the right mattress height.


What is the Average Thickness of a Mattress?

What is the Average Thickness of a Mattress?

The average mattress thickness ranges from 8 to 12 inches. However, many sleepers also prefer a mattress that is a bit thicker than the standard thickness. With this, mattresses that are 14 inches thick are also popular. 


What Influences Mattress Thickness?

If you are wondering why mattresses differ in their height, take a look at these components that affect the mattress thickness.


Mattress Comfort Layer

Mattress Comfort Layer

The comfort layer of your mattress is the uppermost layer and is characterised by its soft and plush feel. This top layer is usually made of soft memory foam or latex that works directly in contact with your body, thus improving its comfort. The comfort layer is usually thinner than other mattress layers. However, softer mattress types will have thicker comfort layers.


Support or Base Layer

Support or Base Layer

The support layer of your mattress is thicker and firmer than the comfort layer. Due to their firmness, mattresses with thick base layers are more durable and less prone to sagging. Common base layers are made from firmer foam, latex, or innerspring materials. Modern mattresses feature pocketed spring layers that respond well to movements. To ensure the quality of your mattress, its base layer should comprise 50 percent of its overall height.

Hybrid mattresses come with other extra layers, like a cooling gel layer to achieve better breathability and a transition layer for proper weight distribution. These hybrid mattresses can be on the thicker side of the spectrum.


What Are the Benefits of a Thick Mattress?

What Are the Benefits of a Thick Mattress?

Thicker or taller mattresses in Singapore can offer multitudes of benefits for different types of sleepers. Aside from their luxurious feel, thick mattresses are ideal for side sleepers who need extra support for their hips and shoulders to sink in. Moreover, taller mattresses are good for couples or mattress sharers since they can handle more weight than thinner mattresses. 

However, in order to properly weigh your options, you should also research the disadvantages of this mattress type. One of the few drawbacks to buying a thick mattress is its price. This is because many thicker mattresses feature extra cooling or support layers that improve their performance. People with limited mobility may also have a hard time getting in and out of a thick mattress.


Mattress Thickness Chart

There is no one-size-fits-all when it comes to choosing the best mattress height. In fact, the right mattress thickness will vary based on the sleeper’s needs, body type, and preferences. Here’s a summary of mattress thickness levels and their applicable uses.

Things to Consider When Choosing Your Mattress Thickness

The ideal mattress height for regular use should at least be 8 inches, or the standard mattress height. If you are using a bunk bed, make sure to follow the bunk bed mattress requirements. Buy the best mattress height for your needs by considering these factors.


Sleeping Position

Sleeping Position

Your dominant sleeping position is important in general when choosing your mattress. If you are always sleeping on your side, your body will need a thicker mattress to support your pressure points. Back sleepers don’t need a mattress that is too thick, but they do need enough back support and firmness to prevent back pain and muscle thickness. Stomach sleepers need a mattress with a firmer base to prevent unnecessary curving of the back.


Body Type

Body Type

Your mattress's materials and thickness can influence how your bed responds to weight pressure. While thin, standard mattresses can benefit children and light sleepers, heavier sleepers will require a thicker support to conform to their bodies. Mattress sharing and pregnancy are other important factors to consider, as these require a thicker and more supportive mattress.


Sleeping Needs

Sleeping Needs

People with back pain tend to benefit from a medium-firm mattress with a standard thickness level. Depending on the preference, a mattress that is 12 inches thick is also beneficial for people with back pain, as it provides the right sinking feel without fully sagging. Those with hip or shoulder pain will benefit from a thicker mattress with proper cushioning to relieve pressure on the parts of their bodies that receive the most pressure.




The right mattress thickness for the bedroom is determined by your sleeping position, body type, physical condition, and comfort preferences. The height of your bed is also an important consideration.
