What a mattress warranty covers, what voids it, how prorated coverage works, and the sag thresholds and foundation requirements brands publish.
A mattress warranty is a manufacturing-defect contract, not a satisfaction guarantee and not a promise about lifespan. The length in the headline matters far less than three details buried further down: the sag threshold, the foundation requirement, and where prorated coverage starts.
| Term | What it means | Why it matters |
|---|---|---|
| Non-prorated period | The remedy is not reduced based on age during that period | Other conditions or charges may still apply |
| Prorated period | You pay a share that grows with age | A 25-year warranty can be mostly prorated |
| Sag threshold | Specified depth and measurement conditions for an eligible claim | Check whether the wording includes the stated depth |
| Foundation requirement | Required base type, slat gap, center support | Inadequate support can affect a claim |
| Void conditions | Stains, cover removal, commercial use, wrong base | The effect depends on the applicable warranty and facts |
| Transferability | Whether coverage survives resale or gifting | Usually not transferable |
What a warranty covers
Many warranties cover defined manufacturing defects, potentially including qualifying body impressions, damaged coils, or certain cover and zipper defects. Coverage varies by model and document. Comfort preference alone is generally handled under a separate sleep trial or return policy, if one applies.
The three numbers to read before you buy
Start with the non-prorated period and any transportation costs, the exact impression threshold and measurement method, and the foundation requirements including slat spacing. Also check who is eligible, what else is covered or excluded, and the cost of a later remedy.
How prorated coverage really works
After a non-prorated period, some warranties require a share of the replacement price, which may be based on the original price or the then-current retail price. Others describe a repair charge. Check the price basis, schedule and transportation terms for your model; a longer warranty does not necessarily mean a free replacement throughout its term.
What voids coverage
Warranties can exclude certain stains or damage, improper support, cover removal or commercial use, but the language differs. Some policies link the exclusion to damage that caused the defect; do not assume every mark automatically defeats every claim. A protector and compliant foundation may help prevent problems, but neither guarantees coverage. Note that warranty exclusions and actual service life are different questions — a bed can be well past its useful life with the warranty still technically intact.
Preparing a warranty claim
Keep the original receipt and law tag; both are usually required. Photograph the whole bed, foundation and slats. Measure an impression without weight using the manufacturer’s instructions; methods and support-surface requirements can differ. Submit the evidence through the designated claim channel.

Published warranty terms by brand
These are examples from manufacturer documents, checked October 30, 2026. They are starting points, not a substitute for the terms tied to your model, purchase date and seller.
| Brand | Examples from current published terms | Important distinction |
|---|---|---|
| Helix | Limited lifetime for eligible purchases after Feb. 1, 2025; later remedies are prorated. | Current wording says an impression must be greater than 1.5 inches; model and support conditions apply. |
| Brooklyn Bedding | Current eligible purchases have limited lifetime terms with later prorated charges. | Older terms can differ; check the warranty for your purchase date. |
| Purple | Current U.S. mattress warranty is 10 years; cover defects have separate terms. | Current visible-impression wording says greater than one inch after full recovery. |
| Tempur-Pedic | Current mattresses generally have a 10-year limited warranty; older purchase periods differ. | Current defect guidance distinguishes non-quilted and quilted tops; confirm the document for your model. |
| Avocado | Some models have 25-year terms; Eco Organic and others have 10-year terms. | Thresholds, rotation, and prorated charges vary by model; published boundary wording differs. |
| Nectar | Current Forever Warranty has different remedies in its first and later periods. | Its FAQ and detailed policy differ at exactly 1.5 inches. |
| Saatva | Standard lifetime terms and Solaire terms have different remedies. | After the initial period, repair and the optional Fairness Replacement follow different cost rules. |
| DreamCloud | Current Forever Warranty covers eligible defects for the original purchaser. | Ask which version applies to an older purchase and clarify any claim charges. |

Frequently asked questions
Does a 25-year warranty mean the mattress lasts 25 years?
No. It is a defect contract, often heavily prorated in later years. Useful life is driven by materials and use.
What voids a mattress warranty fastest?
Potential issues include improper support, certain stains or damage, and removing a cover. The result depends on the warranty wording and circumstances.
Do I need the law tag to file a claim?
Usually yes. Most brands require the law tag and proof of purchase, so never cut the tag off.
Is a mattress warranty transferable?
Rarely. Most cover the original purchaser only, which matters for secondhand beds.
Is a comfort complaint a warranty claim?
Comfort preference alone is generally a trial or return issue. If you suspect a separate defect, ask the warranty administrator to evaluate it under the applicable terms.
