A mattress lasts about seven to ten years by Sleep Foundation's estimate. In its words, "Most mattresses should last between 7 and 10 years." Its own averages by mattress type run lower, from 5.5 to 8.5 years. So the fair answer is a range, and the signs in your own bed count for more than its age.
Mattress lifespan means how long a bed keeps supporting you comfortably. That is a separate thing from how long the maker's warranty runs. Merit Home Furniture has four stores on Vancouver Island, and online mattress orders go through our Duncan store. This guide sets the named sources side by side, then covers wear, care and replacing a bed on the Island.
How long does a mattress last? What four named sources say
The four best-known answers to how long a mattress lasts differ more in tone than in years. Each is quoted below in its own words, with the date on the page.
| Source | What it says | Page date |
|---|---|---|
| Sleep Foundation | "Most mattresses should last between 7 and 10 years." | Updated July 15, 2025 |
| Better Sleep Council | A seven-year-old set "has reached the end of the line", which it calls "a good rule of thumb" | April 14, 2017 |
| Consumer Reports, quoted by NBC 5 Dallas-Fort Worth | "There is no time limit." Still comfortable at 12 years? Then "keep it." | Updated October 26, 2015 |
| Journal of Chiropractic Medicine study | Volunteers' own beds averaged 9.5 years old before new ones went in | 2009 |
Read together, the sources agree on more than the table suggests. Sleep Foundation and the Better Sleep Council both treat seven years as the point to start checking. The Better Sleep Council is "the consumer-education arm of the International Sleep Products Association", the bedding industry's trade body, so its seven-year line comes from sellers.
Consumer Reports was arguing against replacing on a calendar. Its home and appliance editor, Bob Markovich, said its test mattresses still "kept their shape" after the equivalent of eight years. Age starts the question, and the sleeper's own back and sleep settle it.
The Better Sleep Council suggests a habit worth copying. Check the mattress for comfort and support "twice a year when you adjust your clocks for seasonal time changes".
Can a mattress last 20 years?
None of the four sources puts typical mattress life anywhere near 20 years. The longest figure in the table is the 12-year example from Consumer Reports, and it came with a condition: the bed still felt comfortable. A 20-year-old mattress that still sleeps well fits that condition. Nobody in the table expects a new one to get there.
Mattress lifespan by type: foam, coil, hybrid and latex
Construction changes the estimate. Sleep Foundation's averages by mattress type are below, each beside a Merit bed of that build listed for our Duncan store. Prices were read from our product pages on October 9, 2026, before applicable taxes.
| Type | Sleep Foundation average | Example on our listings |
|---|---|---|
| Innerspring (coil) | 5.5 to 6.5 years | Restwell Canary, a firm 5-zone pocket coil bed: double $849.00, queen $899.00 |
| Foam | 6 to 7 years | No Duncan listing describes an all-foam bed; the Restonic Minto and Notte put memory foam over coils instead |
| Hybrid | 6.5 to 7.5 years | Restonic Notte, 15 inches, copper memory foam and nano coils over zoned pocket coils: queen $1,688.00 |
| Latex | 7.5 to 8.5 years | No all-latex bed listed; the Restonic Treviso has a 1-inch Talalay latex layer: queen $2,599.00 |
The 7 to 10 years in the opening line and these averages sit on the same Sleep Foundation page. The averages are lower, so I'd plan on the figure for your type and count anything past it as a good result. The spread from the shortest average to the longest is three years.
For memory foam, the maker's view and the independent one differ in kind. Tempur-Pedic Canada says that once its mattress is broken in, it "retains the responsiveness it has straight from the factory". That is a maker describing its own product, with no years attached. Sleep Foundation's independent average for foam is the 6 to 7 years in the table.
Which mattress type lasts the longest?
Latex has the longest average in Sleep Foundation's table, and innerspring the shortest. We list no all-latex mattress at Merit. The Treviso, listed for our Duncan store, carries latex as a comfort layer over zoned pocket coils, which makes it a hybrid by build. The gap between foam, hybrid and coil builds runs well past lifespan, into feel, heat and price.
How do you tell if you need a new mattress?
A worn mattress usually shows in how you sleep before it shows on the surface. The Better Sleep Council lists five signs, given here in its own words:
- Morning aches. "You wake up with stiffness, numbness, aches and pains."
- Better sleep away from home. "You realize you got a better night's sleep somewhere other than your own bed."
- Visible wear. The mattress "sags, has visible tearing, ripping, holes, staining or damage".
- Tired anyway. "You are usually tired despite getting a full night's sleep."
- Age. "Your mattress is seven years old or older."
Sleep Foundation asks nearly the same questions, ending with "Has it been 7+ years since you purchased your bed?" Age alone is the weakest of the signs. Paired with any of the others, it points toward replacing the bed.
A dip you can see is easy to measure. Lay a straight edge across the bare bed with nobody on it and measure the gap at the deepest point. Each maker sets its own depth for a defect, and the sag depth each mattress maker allows is set out brand by brand in our warranty guide.
Waking up with aches or pains
Back discomfort on waking is the sign with a study behind it. A 2009 paper in the Journal of Chiropractic Medicine moved 59 healthy adults from their own beds to new medium-firm ones. Each person rated sleep and back discomfort for 28 nights on each bed.
Their old beds averaged 9.5 years. The authors concluded that "new bedding systems increased sleep quality and reduced back discomfort" in that group. It was one small study of people with minor pain, so I'd read it as a pointer. Pain that wakes you, runs down a leg or comes with numbness is a question for your doctor first.
Why a mattress warranty is not a lifespan
A mattress warranty answers a narrower question than lifespan: whether a fault is the maker's to fix. Each maker writes its own terms. Tempur-Pedic Canada says "the duration and protection offered under each limited warranty vary by type of product."
The years printed on a warranty are a poor guide to when a bed will be done. Restonic gives the Notte a 10-year non-prorated warranty, longer than the hybrid average in Sleep Foundation's table. A mattress can feel worn well before any dip reaches the depth its maker treats as a defect. Equally, a bed can outlast its warranty and keep sleeping well, which is the Consumer Reports point. Appliances show the same gap between warranty and working life, set out in how long a fridge or washer keeps running.
On a warranty claim, Merit stands behind the maker's terms, sources the parts and handles the repair. SmartOne from Zucora is the extended plan we offer, and its five years of cover are available on a mattress like anything else we sell. For any claim, the paperwork matters. Tempur Sealy's care guide tells hotels "do not remove the law tag label from the head of the mattress" and to keep the invoice on file.
Spills raise their own warranty questions, which the guide to what a protector does for a warranty works through.
Sleep position, body weight and the base underneath
Sleep position and body weight both change how fast a mattress wears. Sleep Foundation says "The position you sleep in, as well as your body weight, will affect how quickly your mattress wears out." It names two patterns:
- "Heavier sleepers may find that their mattresses begin to sag prematurely."
- "Side-sleepers may find excessive sagging around the hips and shoulders."
Neither is a reason to avoid a mattress type. They are reasons to rotate the bed where its maker allows it, and to expect the low end of the range when both apply.
The base under the mattress matters as much as the person on it. Tempur-Pedic Canada says sagging "is likely because the mattress is not properly supported on a flat, solid surface." On a platform bed, it wants 3-inch slats spaced 4 inches or less. Tempur Sealy's hotel guide also advises against "reusing old support systems with new mattresses".
Our Duncan store lists no box spring, flat foundation or platform base from Restwell or Restonic. The Restwell bases listed for Duncan are adjustable ones. The Restwell Peak is $999.00 in twin XL and $1,249.00 in queen, before applicable taxes. An old slatted frame kept under a new bed is worth measuring against the Tempur-Pedic rule first.
A Beautyrest or Tempur-Pedic bed is better matched to its own maker's base, and Merit keeps those with the stores that carry the beds. The 9-inch Beautyrest Traditional foundation is at our Campbell River and Port Alberni stores. The solid 5-inch Tempur Flat foundation is at Campbell River only. Neither shows a price online, so a call to that store gets our best price.
Mattress care and maintenance that keeps the years you paid for
Mattress care comes down to rotation, a cover and keeping the bed dry. Makers disagree on rotation, so the care card for your model wins. Tempur Sealy's hotel care guide says to rotate a one-sided mattress 180 degrees every 3 months. Tempur-Pedic Canada says its own beds are "designed so you do not have to flip or rotate them".
A cover is inexpensive protection for a mattress. Tempur Sealy's guide says covers "help prevent permanent damage to mattress layers". The Health Guard Premium Terry protector is waterproof and machine washable, at $69.00 in queen and $49.00 in twin. A protector bought with a new mattress comes out on the same delivery, and on its own it's a free pickup in Duncan.
Damp is the Island's part of the story. Tempur Sealy's guide says "Mattresses should never get wet" in plain terms. Health Canada says mould "can grow in damp or wet areas in your home" and advises keeping indoor humidity "between 30% and 50%". A hygrometer, a small humidity gauge, will show whether a cold spare room sits above that.
When patching an old mattress is the wrong call
Some fixes buy a worn mattress time and some only hide the problem. These are the cases where I'd stop stretching its life.
Can a mattress topper stand in for a new mattress?
A topper adds a comfort layer on top of whatever is underneath, dip included. Sleep Foundation's view is that "a topper should only be a temporary fix, not a permanent solution" for a mattress on its last legs. We don't list toppers at Merit. The choice here is between a stopgap and a new bed.
- A dip you roll into. A topper follows the shape of the sag beneath it.
- Morning stiffness, numbness or aches. They head the Better Sleep Council's list of signs.
- A bed that has been soaked or shows mould underneath. Health Canada's mould page covers clean-up and the health side.
- A new mattress going onto a tired old base. Tempur Sealy's hotel guide advises against it.
Will my old mattress be taken away when the new one arrives?
Old mattress removal is available from the Merit store in Duncan, for a fee. Duncan's take-away service for old furniture runs $25 to $50 a piece and is sometimes included. Ask whether that covers your mattress and base when you book delivery. The other three stores set their own terms, so ask them directly.
A new mattress delivered from Duncan costs $150 across the Island, assembly included, and some Gulf Islands can be served, with details from the Duncan store. A mattress going across the Island may need a different shipping method, so ask before counting on the truck. Pickup at Duncan is free. A mattress order is ready for pickup or delivery in 2 to 3 weeks.
Choosing the next bed is its own job. The short set of finder questions sorts the options by sleep position and feel, and Tempur-Pedic beds on the Island have a guide of their own. Every bed we list, priced or call for price, sits in the mattress and sleep collection, and the hub for mattress and sleep reading gathers the rest.
