Here are some of the top questions people ask about online mattresses:

Is buying a mattress online right for me?

Buying a mattress online is a convenient option for researching and comparing different products. Purchasing online is quick and easy in most cases.

Most online mattress companies offer a sleep trial period with free shipping and returns. This means people can test the mattress for a set period with the option to return the mattress if they are not content.

Some people may prefer going to a store where they can test the mattress in person. This is particularly useful for people who are unsure what type of mattress they want.

What type of online mattress should I buy?

Individuals looking to purchase a new mattress should consider:

  • Bed support: Different bed frames will fit different mattress sizes, so individuals should ensure the mattress is compatible with their bed frame.
  • Firmness: A 2021 study found that a medium-firm mattress promotes spinal alignment, comfort, and sleep quality. Medium-firm mattresses are ideal for improving sleep quality for most people. However, firmness is subjective. Some people may prefer a plush feel, while others may prefer firm mattresses.
  • Materials: This differs between personal preferences. Mattress options can include foam, spring, or gel.

The quiz below may help people choose a mattress that suits their needs and preferences:

How long do mattresses usually last?

The average mattress can last around 7 years before a person will need to replace it.

How long a mattress lasts depends on how an individual takes care of it, including whether they use a mattress protector, the temperature and humidity in the room, and whether they rotate the mattress frequently.

Most companies on this list provide warranties for their mattresses that can last between ten years and a lifetime.
