How to Choose a New Mattress

When it comes to choosing a new mattress, there are two types of things you must consider: (1) what type of sleeper you are, and (2) the basic qualities of mattresses available on the market. By considering your unique sleeping qualities within the context of what types mattresses are available, you’ll be able to narrow your options significantly.

Please note that although we’ve found that certain mattress types tend to work better with certain types of sleepers, mattress preference is ultimately subjective. Consequently, we recommend going to a local store and trying different mattress types before purchasing online.

What type of sleeper are you?

Sleeping Position

Everyone has their favorite position to sleep in. Different positions have different support requirements, so your ideal mattress will depend on whether you are a side, back, stomach, or combination sleeper. In general, stomach and back sleepers prefer firmer, less conforming mattresses while softer or conforming mattresses are perfect for supporting side sleepers.


Heavier sleepers tend to sleep hotter (see below) and experience more sinkage on soft mattresses than their lighter peers. Most lighter sleepers tend to choose softer mattresses while heavier sleepers prefer firmer options. Supportive, less-conforming mattresses like innerspring and hybrid choices are also popular among heavy sleepers.

If you have a different preference than what is suggested for your weight group, make sure your mattress provides adequate support. For example, a heavier side-sleeper might choose a latex or foam mattress to avoid problems with pressure points. This is perfectly fine so long as it provides support and is not too difficult to move on.

Do you sleep cool or hot?

Some mattresses sleep warmer than others. For example, soft, conforming mattresses allow less airflow around your body and trap more heat than firmer options. Mattress material can also retain heat, like foam mattresses with solid support cores. If temperature regulation is an important factor for you, consider choosing a hybrid or innerspring mattress style. These allow for more air circulation and sleep considerably cooler.

Mattress Qualities to Consider


Five material types make up the bulk of mattresses on the market. These include:

InnerspringSteel coils support a comfort layer of polyfoam
FoamEither pure polyfoam or a combination of supportive polyfoam and memory foam
LatexLatex or high-density polyfoam support core with a natural or synthetic latex comfort layer
Hybrid2+ inches of memory foam or latex for comfort and pocketed coils for support
AirbedAir chambers are inflated or deflated to reach the desired firmness


Most mattresses are available in six standard sizes: Twin, Twin XL, Full/Double, Queen, King, and California King. Some models come in additional sizes (such as Full XL or Short Queen). They may also be available in ‘split’ Queen, King, or California sizes, which include two separate mattresses that can be pushed together or separated.


Most mattresses measure at least 10 inches (10?) in height, though mattress thickness varies from less than five inches (5?) to more than 15 inches (15?). Your body weight may affect your preferred thickness. Lighter individuals may prefer shorter beds, whereas heavier people tend to feel more comfortable on thicker beds.
