Shopping for a new mattress can feel overwhelming. With so many options available, it’s easy to focus only on how a mattress feels in a showroom—but knowing what to look for when buying a mattress goes beyond initial comfort.

From long-term protection to flexibility and support after purchase, here are the key factors to consider when choosing the right mattress for your needs.

Look for a Mattress Warranty That Protects Your Investment

When buying a mattress, one of the first things to consider is the warranty. A mattress is a long-term purchase, and the warranty can give you insight into how a brand stands behind its product.

What to look for:

  • Coverage for defects

  • A mix of full coverage and extended limited coverage

  • Clear support if something goes wrong

Sleep Number mattresses, for example, are covered by our 10- Year Limited Warranty. With full warranty coverage from the date of delivery for the first two years. Beginning on the second anniversary of your original delivery date until the tenth anniversaryyou’ll share in the cost of repairs and replacements parts under the 8-year Limited Warranty and your portion will be based on a prorated amount.
