Quick Answer: Most Canadian mattress warranties cover manufacturing defects and body impressions deeper than 1.5 inches (sometimes 1 inch for premium models), but normal softening, surface wear, and impressions under the threshold are not covered. IKEA mattress warranties run 25 years but come with strict conditions; most independent retailers offer 10-year coverage. Keep your receipt, use a mattress protector, and document impressions with a photo and ruler if you plan to make a claim.

Every year, Brad fields calls from customers who bought a mattress somewhere else , sometimes years ago , confused about why their warranty claim was denied. The story is usually the same: the mattress has developed a noticeable dip, the store points to a clause they never read, and the customer feels stuck.
Mattress warranties are not consumer protection policies. They are manufacturing defect guarantees, and the fine print matters enormously. Here is what you need to know before you buy, and what to do if you already need to make a claim.
What Mattress Warranties Actually Cover
A standard mattress warranty covers two categories of manufacturing defects:
- Structural defects: broken or protruding coil springs, split or cracked foam cores, torn handles that cause the mattress to lose structural integrity
- Body impressions: permanent indentations that exceed a specified depth threshold (typically 1.5 inches, sometimes 1 inch for higher-end models)
What warranties do not cover is just as important:
- Normal softening or change in feel over time
- Impressions below the threshold (a 1.4-inch dip on a 1.5-inch warranty covers nothing)
- Comfort preference changes
- Stains, odours, or damage from improper cleaning
- Physical damage from misuse, moving, or improper support
The Science Behind Body Impressions
All mattresses develop some degree of impression over time. Research published in Applied Ergonomics (Verhaert et al., 2012) found that foam materials deform under sustained loading , this is normal visco-elastic behaviour, not a defect. The question is whether the impression is permanent and deep enough to indicate a manufacturing failure versus expected use wear.
This is why most warranty claims are denied: the mattress is softening normally, but not to a degree the manufacturer considers defective. The impression threshold exists to separate genuine manufacturing failures from expected material behaviour.
Understanding Body Impressions
A body impression is a permanent indentation in the sleep surface that remains after the mattress has rested unloaded for 24-48 hours. This is the key distinction: temporary compression from lying down is normal. A permanent dip that stays even when nobody is on the mattress is a potential defect.
To measure an impression for a warranty claim, you need:
- A straight edge (a level or yardstick works well) placed across the mattress from the non-indented edges
- A ruler to measure the deepest point of the indentation vertically
- A clear photograph with the measuring tools in frame
- The measurement taken on a flat, supportive foundation with no one on the mattress
Most claims are denied because customers measure while sitting on the edge, or because the foundation itself has sagged , causing an impression that looks like a mattress defect but is actually a support problem.
Dorothy, Sleep Specialist: "Nine times out of ten when someone calls about a body impression, the first thing we ask is: what's underneath the mattress? A worn box spring or a slatted frame with gaps wider than three inches will cause impressions faster than the mattress itself. Always address the foundation first before assuming the mattress is defective."
IKEA Warranty vs. Independent Retailers
IKEA's 25-year mattress warranty sounds impressive, and the company has put real effort into making it consumer-friendly. For the standard IKEA mattress warranty claim, the threshold is 1.5 inches. The conditions are strict but clearly written.
However, there are practical differences worth understanding:
| Factor | IKEA Warranty | Restonic at Mattress Miracle |
|---|---|---|
| Length | 25 years | 10 years (prorated after year 2) |
| Impression threshold | 1.5 inches | 1.5 inches (1 inch on premium models) |
| Claim process | In-store return, online claim | Through Mattress Miracle + Restonic |
| White glove service | Not included | Professional delivery and setup |
| Local support | Nearest IKEA store | Call (519) 770-0001 directly |
| Foundation requirements | IKEA-compatible slats required | Adequate support required |
The most significant practical difference: when you buy from Mattress Miracle, you call us directly. Brad can often diagnose the issue over the phone, advise on whether a claim makes sense, and coordinate with Restonic on your behalf. With a big-box retailer, you are typically navigating a call centre.
The 25-year IKEA warranty is also prorated , meaning the replacement value decreases significantly after the first few years. A 20-year-old mattress claim might result in a credit that does not cover much of a replacement purchase.
How to File a Mattress Warranty Claim
If you believe your mattress has a genuine defect, here is how to approach a mattress warranty claim in Canada.
Step 1: Gather Documentation
- Original receipt or proof of purchase (required by every manufacturer)
- Mattress model name and serial number (usually on a law label attached to the mattress)
- Photos of the defect with a ruler or straight edge showing the depth
- Photos of the foundation showing it is in good condition and provides adequate support
Step 2: Contact the Retailer First
In Canada, your purchase contract is with the retailer, not the manufacturer. Start the claim through the store where you bought the mattress. If you bought from Mattress Miracle, call us at (519) 770-0001 and we will handle the manufacturer correspondence for you.
Step 3: Manufacturer Inspection
For claims above a certain value, the manufacturer may send a representative or request that you bring the mattress in. They will verify the defect against warranty terms. This is why documentation matters , verbal descriptions are not sufficient.
Step 4: Resolution
If the claim is approved, resolution typically means a replacement mattress of equal or comparable value, or a prorated credit toward a new one depending on the age. Cash refunds for warranty claims are rare.
Pro Tip: Protect Your Warranty from Day One
Use a quality mattress protector from the first night. A stain on the mattress is one of the most common reasons manufacturers deny otherwise valid warranty claims. Our mattress protectors are waterproof, breathable, and will not affect the feel of the mattress.
What Voids Your Mattress Warranty
These are the conditions that most manufacturers cite when denying claims. Avoiding them protects your coverage:
Improper Foundation
This is the most common claim denial. Every mattress requires a foundation that provides adequate, even support. Restonic mattresses require slats no more than 3 inches apart, a solid platform, or a box spring in good condition. A slatted frame with wide gaps will cause premature sagging that the warranty does not cover.
Physical Damage
Moving a mattress improperly (bending it sharply, dragging it, using it as a trampoline) can damage internal components. Damage caused by the customer during moving or use is excluded from coverage.
Staining
Any staining, including liquid damage from a broken water bed on an adjacent frame, typically voids the warranty. This applies even when the stain seems unrelated to the defect. Keep the law label intact, too , removing it voids coverage with most manufacturers.
Unsupported Use
Using a mattress on the floor (particularly on concrete) without a moisture barrier, or using a single mattress on a frame designed for a larger size, can cause wear patterns that manufacturers exclude.
What We See in Brantford
In our experience helping Brantford families over 37 years, the most preventable warranty issue is the box spring. Southern Ontario homes often have older metal box springs that have compressed over time. When you place a new mattress on a compromised foundation, the mattress conforms to the foundation's dips within months. The mattress warranty will not cover this because the root cause is the support system, not the mattress itself. When Brad delivers to homes in Paris, St. George, or Brantford's west end, he will always check the foundation before setup.
Restonic Warranty at Mattress Miracle
All Restonic mattresses sold at Mattress Miracle come with a Restonic manufacturer's warranty. Our current lineup covers:
| Model | Queen Price | Coils | Warranty Notes |

| ComfortCare | $1,125 | 1,222 | 10-year warranty, 1.5" impression threshold |
| Revive Reflections ET (flippable) | $1,395 | 1,200 | 10-year, both sleep surfaces covered |
| Luxury Silk & Wool | $1,395 | 884 zoned | 10-year, premium impression threshold |
| Revive Tiffany Rose / Jasmine | $1,995 | 1,188 | 10-year, Talalay Copper Latex covered |
| Revive St. Charles / Elizabeth | $2,150 | 1,188 | 10-year flagship warranty |
We walk through warranty conditions at purchase so there are no surprises. Brad keeps a record of every mattress sold , model, size, purchase date , so if you call years later, we can pull up your mattress history without you needing to find the original receipt.
For those considering long-term durability, our foam vs. flippable mattress guide explains why flippable designs like the Revive Reflections ET often outlast single-sided foam mattresses , and why that matters for warranty protection over the life of the mattress.
If you are buying for a guest room or spare bedroom, our first apartment mattress guide covers the cost-per-year math on entry-level versus mid-range options, which also affects how much warranty coverage matters for your situation.
After the Warranty Expires
A mattress warranty expiring does not mean your mattress automatically needs replacement. The Sleep Foundation and many sleep researchers suggest replacing mattresses every 7-10 years based on performance, not paperwork. If you are sleeping well and the mattress is still supportive, you may have more life left in it. If you are waking with stiffness or the surface has noticeably softened, it may be time regardless of warranty status.
Our mattress lifespan guide covers the signs that indicate it is time for a replacement, and what to look for in the showroom when you visit.
Frequently Asked Questions
How do I measure a body impression for a warranty claim?
Place a rigid straight edge (a long level or yardstick) across the mattress from one non-indented edge to the other. Use a ruler to measure the deepest point of the dip vertically. Take the measurement with nobody on the mattress and on a flat, supported foundation. Photograph the measurement with the ruler clearly visible. The impression must remain after 24-48 hours of the mattress being unloaded to count as permanent.
Does IKEA's 25-year mattress warranty cover everything?
No. IKEA's warranty covers manufacturing defects and body impressions exceeding 1.5 inches, but it is prorated after the initial period, meaning the replacement value decreases each year. Normal softening, comfort preference changes, and impressions below the threshold are excluded. The warranty also requires use with an IKEA-compatible foundation, and staining may void the claim.
Can a stain void my mattress warranty?
Yes, most manufacturers use staining as grounds to deny warranty claims, even if the stain seems unrelated to the defect you are claiming. This is one of the most common reasons valid impressions go uncompensated. A waterproof mattress protector from day one prevents this entirely.
What is the difference between a warranty claim and a comfort exchange?
A warranty claim is for manufacturing defects covered under the manufacturer's guarantee. A comfort exchange (where the retailer allows you to swap a mattress you dislike) is a store policy, not a legal right, and varies widely by retailer. At Mattress Miracle, we encourage showroom testing before purchase precisely because we want you in the right mattress from the start, which removes the need for exchanges.
My mattress is 8 years old and has a dip. Is it worth claiming under warranty?
It depends on the impression depth. Measure it accurately against your warranty threshold. If it exceeds the threshold, the claim is valid regardless of age (within the warranty period). If it does not exceed the threshold but the mattress feels significantly different from when you bought it, that is normal material ageing and is not covered. In either case, after 8 years you may find a replacement serves you better than pursuing a prorated credit.
