How long do mattress warranties typically last?

Warranty lengths vary by brand and model, often ranging from several years to a decade or more; specific terms are provided with your mattress at the time of purchase.

Does normal body impression count as sagging?

Most manufacturers allow for some depth of body impression as normal wear before it is considered a defect; the exact threshold is specified in the warranty documentation.

Will using an incompatible frame void my warranty?

Yes, using a foundation or frame that does not meet the manufacturer's support requirements can void warranty coverage.

What should I keep in case I need to file a claim?

Keep your original receipt or order confirmation and take note of your mattress's model and purchase date in case you need to reference them later.

Mattress Warranties Explained

A mattress warranty generally covers manufacturing defects, such as abnormal sagging or broken coils, for a set number of years after purchase, but it does not cover normal wear, comfort preferences, or damage from improper use. Understanding what is and is not covered can help you care for your mattress and know when a warranty claim applies.

What a mattress warranty typically covers

Visible sagging beyond the depth specified by the manufacturer, when the mattress has been used on a proper, supportive foundation.
Physical flaws in materials or workmanship, such as broken coils or seams that split under normal use.
Defects that appear during normal, intended use of the mattress.

What a mattress warranty typically does not cover

Normal softening or body impressions within the manufacturer's specified depth limits.
Comfort preferences — a warranty addresses defects, not whether you personally like the feel of the mattress.
Stains, odors, or damage from spills, pets, or improper cleaning.
Damage caused by using an incompatible, unsupportive, or damaged foundation.
Mattresses that have been used on the floor without a proper frame or foundation, if required by the manufacturer.

Mattress warranty versus Comfort Guarantee

It's important not to confuse a manufacturer's warranty with our 120-Night Comfort Guarantee. The warranty addresses long-term manufacturing defects, while the Comfort Guarantee addresses whether the mattress feels right for you shortly after purchase.

Covers	Manufacturing defects	Comfort and fit
Typical length	Multiple years, varies by brand	120 nights from delivery
Outcome	Repair or replacement	Exchange or return

Steps to protect your warranty coverage

Use a supportive, compatible foundation or frame as specified by the manufacturer.
Rotate the mattress periodically if recommended by the manufacturer.
Use a mattress protector to guard against stains and spills.
Keep your receipt and order information in case you need to file a claim.
Avoid folding, bending, or using the mattress in ways not intended by its design, especially with adjustable bases unless the mattress is rated compatible.
