How to buy a mattress - Which? guide

Understanding Your Sleep Needs

The first step to buying a mattress is understanding your sleep needs. Consider the following factors:

Sleeping Position

Whether you sleep on your side, back, or stomach will determine the level of support and comfort your body needs. For instance, side sleepers need a mattress that cushions their shoulders and hips, while back sleepers need one that supports their lower back.

Body Type

Your body weight and shape will also influence the type of mattress you need. A heavier person may require a firmer mattress to provide adequate support, while a lighter person may prefer a softer mattress.

Health Conditions

If you have any health conditions, such as back pain or arthritis, you’ll need a mattress that provides adequate support and pressure relief.

Types of Mattresses

Once you’ve determined your sleep needs, the next step is to understand the different types of mattresses available.

Innerspring Mattress

These mattresses are made of metal coils and are popular due to their affordability and durability. However, they may not provide adequate support and may sag over time.

Memory Foam Mattress

These mattresses are made of viscoelastic foam that conforms to your body shape and provides excellent support and pressure relief. However, they may retain heat and have a chemical smell.

Latex Mattress

These mattresses are made of natural or synthetic latex and provide excellent support, comfort, and durability. They are also hypoallergenic and resistant to dust mites.

Firmness Level

The firmness level of a mattress plays a significant role in determining your comfort level. Firmness levels range from soft to extra firm, and the right level for you will depend on your sleep needs. Here are some guidelines to follow.

  • Soft – Soft mattresses are suitable for side sleepers who require cushioning for their shoulders and hips.
  • Medium – Medium mattresses are suitable for back sleepers who require support for their lower back.
  • Firm – Firm mattresses are suitable for stomach sleepers who require support for their spine.

Mattress Size

The size of your mattress will depend on your personal preference and the size of your bedroom. Here are the standard mattress sizes in the US.

  • Twin – 38″ x 75″
  • Twin XL – 38″ x 80″
  • Full – 54″ x 75″
  • Queen – 60″ x 80″
  • King – 76″ x 80″

Additional Considerations

Apart from the above factors, there are some additional considerations you should keep in mind when buying a mattress. These include:

Motion Isolation

If you sleep with a partner, you’ll want a mattress that isolates motion to prevent disturbance.

Edge Support

A mattress with good edge support will prevent you from rolling off the bed.


If you tend to sleep hot, you’ll want a mattress that promotes air circulation.
