by Quick answer: GhostBed covers most mattresses for 20–25 years against defects, including sag deeper than 1.5 inches. The first 10 years are full coverage; years 11+ are prorated, meaning you pay a percentage plus transport. It's original-owner only.

GhostBed's Warranty Explained
GhostBed's warranty length depends on the model. Classic and Comfort models carry a 20-year term, while Signature, Luxe, Flex, 3D Matrix, and Natural models run 25 years. The warranty is administered by Nature's Sleep. It protects against manufacturing defects, not the gradual softening that comes with normal use.
The structure matters more than the headline number. Coverage is split: full protection early, then prorated charges later. That second phase is where many owners get surprised by out-of-pocket costs.
Key Terms (what we could verify)
| Item | Detail |
|---|---|
| Warranty length | 20 years (Classic, Comfort); 25 years (Signature, Luxe, Flex, 3D Matrix, Natural) |
| Sag threshold covered | Lasting indentation greater than 1.5 inches, not caused by an unsupportive base (older documents cite 1 inch — confirm your version) |
| Who pays transport | You. Handling and transportation costs are excluded, even in the full-coverage period |
| Common exclusions | Normal softening, stains, soiling, damage, and sag from an improper or uneven foundation |

How to File / What to Do
Start by registering the mattress and pulling your proof of purchase, which is required. Strip the bed and photograph the issue. For sag, lay a straightedge across the surface and place a ruler at the deepest point so the depth is visible without anyone lying on it. Then submit the claim through GhostBed's official warranty page with your documentation. The warranty is non-transferable, so it only applies if you bought it new yourself.
Common Problems Owners Report
The most common friction point is the proration. A replacement in year 15 can cost roughly 70% of the original price plus shipping, which on a premium model can exceed $1,000. Owners also report delays in response and disputes over whether an issue is a defect or normal wear. Comfort complaints inside the first 101 nights fall under the sleep trial, not the warranty.
The Saatva Comparison
Saatva takes a simpler position. The Saatva Classic carries a lifetime warranty, and its 365-night home trial gives you a full year to decide. Returns cost a flat $99, and delivery is free white-glove with old-mattress removal included. There's no proration table to decode and no return-shipping bill to absorb if you change your mind.

Bottom Line
GhostBed's warranty is genuinely long, but the prorated back half and customer-paid transport mean a claim is rarely free after year 10. Register early, keep your receipt, and protect the mattress from stains.
Bottom line: GhostBed covers real defects for 20–25 years, but expect to pay proration and shipping on any later-life claim.
