What to Consider When Choosing the Best Full Size Mattress

Taking some time to determine preferences and priorities can help ensure satisfaction with the full size mattress you ultimately purchase. The key considerations below can help you identify and prioritize which full size mattress features are most important to you.

Type

One of the biggest decisions to make before purchasing a mattress is the type of mattress you’d prefer. Some types are better suited to different sleeping positions and needs. There are five main types of mattresses to consider, and each offers its own pros and cons.

  • Innerspring: Innerspring mattresses feature a core designed with steel coils. The coils are covered with foam, such as memory foam or polyfoam, to provide cushioning and comfort. Innerspring mattresses are typically a firmer option preferred by many back and stomach sleepers. They are springier, more responsive, and less contouring than most other mattress types. Innerspring mattresses with individually wrapped coils can limit motion transfer from one side of the bed to the other, which can be a nice benefit for couples sharing a bed.
  • Foam: Foam mattresses are designed with layers of memory foam or polyfoam. Additional layers for support made from a denser foam are typically included with these mattresses. A foam mattress is highly contouring and can offer relief from pressure for all individuals but especially those who sleep on their side. Foam mattresses can be effective at limiting motion transfer.
  • Hybrid: Hybrid mattresses combine features from different mattress types. They typically have a pocketed-coil support core along with other layers made from materials such as memory foam, polyfoam, and latex. A hybrid mattress is supportive but also offers pressure relief and body-conforming properties. The coil design of these mattresses allows for sufficient airflow to regulate the temperature. Since hybrid mattresses often feature individually wrapped coils and often have a layer of memory foam, they can be a good option if you’re looking for a mattress to limit motion transfer.
  • Latex: Made from rubber tree sap and chemical fillers, latex is responsive and offers some contouring properties. Unlike memory foam that sinks in too much for some users, latex prevents individuals from sinking too deep into the mattress. Latex is also more breathable than memory foam and other foam types, so it allows for a cooler sleep space. The elasticity of a latex mattress that allows it to conform to an individual’s body also allows the mattress to reduce the transfer of motion from one side to the other.
  • Pillow top: Pillow-top mattresses typically feature an innerspring base with an additional top layer of padding. This padded top layer is typically between 2 and 4 inches thick and may be made from memory foam, latex, wool, gel, fiberfill, or other plush materials. Pillow-top mattresses are popular with side sleepers since their plush top can be very conforming and take pressure off the joints. The design of the mattress beneath the pillow-top layer will affect how effective this mattress type is at limiting motion transfer.

Pressure Relief

Pressure points are the areas of our bodies where we feel the greatest amount of pressure when lying down. An individual’s sleeping position can affect which areas experience the greatest pressure. For example, side sleepers feel the greatest pressure on their hips and shoulders, while back sleepers feel the greatest pressure on their backs.

Look for mattresses that are designed to provide more even support to the body, as this can reduce the amount of pressure placed on any one area of the body. A hybrid mattress may be the optimal choice for a guest room since it offers more balanced pressure relief and is less likely to be too firm or too soft for individuals with different sleep preferences. A mattress with higher contouring properties typically offers more pressure relief than one that does not contour to a body.

Contouring

Contouring refers to how much a mattress conforms to the body of the individual sleeping on it. A mattress with a lot of contouring properties will create more of a cradle around the body while still offering even support for the hips and torso. Latex, foam, and hybrid mattresses are known for their contouring abilities. A hybrid mattress might be the best option for a guest room since this mattress type can often provide the right level of contouring to keep many back, side, or stomach sleepers comfortable.

Conversely, a mattress that doesn’t have high contouring properties will be stiffer and won’t create that cradle-like shape around a body. Innerspring mattresses are typically less contouring than other mattress types.

Density and Firmness

Mattresses come in a range of firmness options. Manufacturers typically indicate how firm a mattress is using a scale from 1 to 10, with 1 being a very soft mattress and 10 being a very firm mattress. Mattresses on the softer end of the range (with a firmness level between about 1 and 3) will be plusher and allow the body to sink relatively deep into the mattress for a more cradled or contoured feeling.

Mattresses on the firm end of the scale (with firmness levels between 7 and 10) will be quite the opposite; they will offer more support and less contouring around the body. If you are looking for something in between these two levels or share a bed with a partner who may have a different ideal firmness than you, consider a mattress with a medium level of firmness (firmness level between 4 and 6). A medium-firm mattress may also be a good option for a guest bedroom since different guests may have different firmness preferences.

The density of the foam used on a mattress is another factor to consider. Mattresses with high-density foam can offer more support and contouring than mattresses made with low-density foam. For this reason, a high-density mattress is a better option for back sleepers since a low-density mattress won’t offer the support they need. High-density foam can have more of a cradling feel that many sleepers enjoy. However, some individuals don’t enjoy the feeling of sinking into the mattress with it surrounding their body and may opt for a mattress made with low-density foam. High-density mattresses trap heat and may make some sleepers too warm overnight. On the other hand, low-density mattresses allow more air to flow and can help keep individuals cooler.

Temperature Regulation

Some mattresses are constructed with materials that are better at regulating temperature and creating a cooler environment for sleep. Cooling mattresses often feature breathable materials that allow for more air circulation and prevent the mattress from retaining heat.

If you are a hot sleeper and prefer a cooling mattress, consider mattresses with coils that promote airflow or those with gel or graphite infused into the foam layers to deliver cooling benefits. Gel or activated charcoal are sometimes infused into the foam of a mattress to regulate the temperate and keep individuals cool as they sleep. Gel absorbs heat and keeps the mattress’s temperature from getting too warm, and charcoal is a naturally cool substance that helps ensure the foam layer stays at a cool and comfortable temperature all night long.

Cooling materials may also be integrated into the cover of a mattress to make it more breathable. Tencel is one of these materials. It is a very breathable fabric that is able to wick away moisture to make sure individuals don’t get too warm as they sleep. You may also see mattresses that have a phase change molecule (PCM) fabric integrated into the material for the cover. PCM fabrics absorb heat when a body gets too hot. They can then release the heat back if the body cools down too much.

Sleeping Position

A preferred sleeping position can greatly affect which mattress is best. Some sleeping positions require greater support from a firmer mattress than others.

  • Side sleepers. A softer mattress offers relief from pressure on the shoulders and hips. Side sleepers are often most comfortable on a mattress with a firmness rating between 3 and 5 out of 10. A mattress with a firmness rating in this range offers enough give to let the hips and shoulders sink in and prevent pressure points. Side sleepers often prefer memory foam or hybrid mattresses with a memory foam layer that allows for their weight to be more evenly distributed to reduce pressure on the joints.
  • Back and stomach sleepers. A firmer mattress is generally recommended for both. This allows the spine to stay more aligned and offers the necessary support for the shoulders, hips, and head to keep individuals comfortable. When a mattress is too soft, the heavier parts of the body may sink more deeply into the mattress, which can place the spine out of alignment and cause pain the next day. Back sleepers often do well on a mattress with a firmness rating of around 6 or 7 out of 10, while stomach sleepers may be more comfortable on a mattress with a firmness rating of between 8 and 10 out of 10.

Edge Support

The edge support on a mattress can affect how easy or challenging it is to get in or out of bed. Mattresses with weaker edge support are softer around the edges and may sink down when individuals sit on the edge of the bed. A mattress with firmer edge support, on the other hand, won’t sink down as much to simplify the task of getting in or out of bed.

Edge support can also affect the usable sleeping space on the top of the mattress. It is possible to sleep right up to the edge of a mattress with firm edge support but not as easy to do so on a mattress with weaker edge support. Since full size beds are already on the smaller side for two individuals sleeping together, this may be an important item to consider if you’re shopping for a mattress that will be used by two people.
