Mattress Warranty in Canada: What's Actually Covered (and How to Claim It)
A mattress warranty sounds like a safety net, but most claims are denied, usually because the sag is not deep enough or the fine print was missed. This guide explains what a mattress warranty in Canada really covers, the exact sagging depth that triggers a claim, what quietly voids your coverage, and how to file, with the major Canadian brand thresholds compared side by side.
A warranty is not a comfort guarantee; that is what the sleep trial is for, so read this alongside our guide to the best mattress in Canada and our breakdown of how long a mattress lasts.
A mattress warranty in Canada covers manufacturing defects, mainly sagging past a set depth, broken coils, and split or cracked foam. Still, it does not cover normal softening, comfort preference, or stains. The single most important number is the sagging depth threshold: most brands require 1.5 to 2 inches of visible indentation with no weight on the bed before a claim qualifies, and a stain or the wrong base will void the whole warranty.
Threshold is where warranties differ most. The Hamuq Made in Canada Hybrid carries a 15-year warranty that triggers at a visible indentation greater than 1 inch, one of the more consumer-friendly thresholds in Canada, versus the 2 inches some foam brands require. Hamuq covers both shipping methods for a valid claim.
What a Warranty Covers vs What It Does Not
- Sagging or body impressions past the depth threshold
- Broken or protruding coils
- Foam that splits or cracks under normal use
- Seam and stitching failures
- Handles detaching from the body
- Normal softening or a bed that feels different
- Comfort preference, too soft or too firm over time
- Stains, burns, cuts, or liquid damage
- Damage from an unsupportive or wrong base
- Mattresses bought used or from unauthorised resellers
The distinction that trips people up: a warranty protects against manufacturing defects, not against the mattress wearing out or no longer feeling right. If your bed went soft after six years, that is normal wear and not a warranty matter. If it developed a deep, measurable crater while properly supported, that is a defect.
The Number That Matters: Sagging Depth Thresholds Compared
Every warranty sets a sagging depth you must reach before a claim is valid, measured with a straightedge across the surface, with no weight on the bed. The lower the threshold, the easier it is to make a legitimate claim, which is why this single number matters more than the headline warranty length. Here is how major brands sold in Canada compare.
| Brand | Warranty length | Sagging threshold | Easier or harder to claim |
|---|---|---|---|
| Hamuq | 15 years | 1 inch | Easier, lower threshold |
| Serta (all foam) | 10 years | 0.75 to 1.5 inches | Easier on all-foam |
| Beautyrest | 10 years | 1.5 inch | Middle of the pack |
| Douglas | 20 years | 2 inch | Harder, deeper sag needed |
| Silk & Snow | 15 years | 2 inch | Harder, deeper sag needed |
Thresholds summarised from each brand's published warranty terms and Canadian retailer guides, June 2026. Always confirm the current terms on the brand's own warranty page before relying on them.
Notice the trap in that table: Douglas offers a 20-year warranty, the longest here, but requires 2 inches of sag to claim, which is a lot of visible deterioration to wait for. Hamuq's 15-year term is shorter on paper, but its 1-inch threshold means a defect qualifies far sooner. When you compare warranties, read the threshold before the length.
What the Hamuq 15-year warranty actually says
Stripped of legal language, the Hamuq limited warranty covers two things for 15 years: a visible indentation greater than 1 inch that is not caused by an unsupportive base, and any physical flaw that makes the foam split or crack under normal use. If a claim is valid, Hamuq provides a one-time repair or replacement at its option and pays Shipping in both directions. Both Hamuq hybrids are rated to support up to 600 lb.
The conditions are the same ones every warranty imposes, and they are worth taking seriously. The mattress must sit on a base that properly supports the weight of the bed and sleepers. Stains or physical damage void coverage, and the warranty applies only to the original purchaser who bought from Hamuq or an authorised retailer. Buy it used, and there is no coverage. For the full legal text, see the Hamuq warranty page.
What Voids a Mattress Warranty
A single avoidable mistake can wipe out years of coverage, and these are the usual culprits. The biggest is stains: nearly every mattress warranty in Canada is voided by a stain, even a small water mark, because the manufacturer can argue that fluid reached the internal components. That is why using a washable mattress protector from day one is not optional if you want to keep your warranty alive. The second most common is an improper base, slats spaced too far apart, a sagging old foundation, or no centre support on a queen or larger, all of which cause the mattress to sag and allow the manufacturer to deny the claim.
- Stains or liquid damage: use a washable protector from night one.
- The wrong base: slats over 7.5 cm apart, or no matching foundation or centre support.
- Removing the law tag: that little tag you are tempted to cut off keeps coverage valid.
- Buying used or from an unauthorised reseller: coverage extends only to the original purchaser.
- Physical abuse: burns, cuts, tears, and the like.
Before you buy any frame, it is worth checking that it meets the warranty's support rules. Our guide on what bed frame a hybrid mattress needs covers the slat spacing that keeps coverage valid.
How to File a Mattress Warranty Claim
The process is similar across reputable Canadian brands. Done in order, it gives you the best chance of approval.
1. Find your proof of purchase
Receipt or order confirmation showing you are the original buyer from an authorised seller.
2. Measure the straight edge across the bed with no weight on it, and measure the deepest gap.
3. Photograph it
Clear photos of the indentation, straightedge measurement, plus your base.
4. Contact support
Send the brand your proof, photos, and measurements to open the claim.
5. Show proper support
Be ready to prove the mattress was on an approved base; this is the most common reason for denial.
6. Repair or replace
If valid, the brand repairs or replaces at its option; Hamuq covers both ways.
What real Hamuq buyers say
Warranty terms are a trust signal, and what draws Canadian buyers to Hamuq reflects that. Based on 61 surveyed Hamuq buyers who answered why they chose us (responses collected from March to May 2026), 31 per cent cited reviews and reputation, 18 per cent cited price and value, 1 per cent cited being Canadian-made, and 13 per cent cited a referral. A long, clearly worded warranty, backed by a Canadian company, lies behind the reputation and word-of-mouth those buyers cite.
The Made in Canada Hybrid is backed by a 15-year warranty that kicks in at just 1 inch of indentation, includes Shipping, and is available in a queen for $999. The Organic Hybrid carries the same $1,999 warranty for a queen. Both include a 120-night trial.
Frequently Asked Questions
A mattress warranty in Canada covers manufacturing defects, mainly sagging past a set depth, broken or protruding coils, split or cracked foam, and seam failures. It does not cover normal softening, comfort preferences, or damage such as stains and burns. It is a defect guarantee, not a satisfaction guarantee.
Most Canadian warranties require a 1.5- to 2-inch visible indentation, measured with a straight edge with no weight on the bed, before a claim qualifies. Lower thresholds are more consumer-friendly. Hamuq triggers at a visible indentation of more than 1 inch, while some foam brands, like Douglas and Silk and Snow, require 2 inches.
The most common warranty-voiding mistakes are stains or liquid damage, using an unsupported or incorrect base, removing the law tag, and buying a used mattress or from an unauthorised reseller. Using a washable mattress protector and an approved foundation from day one protects your coverage.
Not necessarily. The sagging depth threshold and whether the coverage is prorated matter more than the headline length. A 20-year warranty that requires 2 inches of sag or becomes prorated after a few years can offer less real protection than a shorter warranty with a 1-inch threshold and non-prorated terms. Read the fine print before comparing years.
A sleep trial is a short period, usually 100 to 365 nights, during which you can return the mattress for a refund if it is not comfortable. A warranty is long-term protection, often 10 to 20 years, against manufacturing defects. The trial covers comfort and satisfaction; the warranty covers structural defects. They are not interchangeable.
The Hamuq 15-year limited warranty covers a visible indentation greater than 1 inch on a properly supported bae, and a physical flaw that causes the foam to split or crack under normal use. For a valid claim, Hamuq provides a one-time repair or replacement and pays for both-way Shipping. It does not cover shipping stains, misuse, or comfort preferences and applies only to the original purchaser.
Final Verdict
The headline number on a mattress warranty is the least useful one. What decides whether you can ever claim is the sagging depth threshold and the fine print on stains and support. Measure before you compare years, protect the bed from day one, and keep proof of a proper base. On that scorecard, the Hamuq Made in Canada Hybrid does well: a 15-year term that triggers at 1 inch, with Shipping covered, and the same protection on the Organic Hybrid. Be fair to the competition, though: Douglas offers a longer 20-year warranty and a 365-night trial, so if trial length is your priority, it is worth a look.
