Quick Answer: The best truck mattress in Canada is one built with a high-density foam core (1.7 lb/ft3 or higher), flippable construction for double the lifespan, and reinforced edge support for sleeper cab use. According to the Sleep Foundation, low-density foam (1.2-1.5 lb/ft3) used in most factory and budget truck mattresses loses over five times more height after repeated compression than higher-density foam. Standard sleeper berth sizes range from 32" x 80" to 42" x 80". Mattress Miracle builds custom fleet and individual truck mattresses with 1.7 to 1.9 lb density cores, shipped across Canada.

Canadian long-haul truckers spend 200-300 nights per year in their sleeper cab. That is more time on a truck mattress than most people spend on their home mattress. Despite this, the factory-installed mattresses in most Freightliners, Kenworths, Peterbilts, and Volvos are 4-5 inches of low-density foam that was never designed for nightly use. It is the cheapest component the manufacturer could fit into the bunk, and it shows after the first month.
This guide covers the best replacement truck mattresses available to Canadian drivers, including Canadian-made options that ship domestically, US brands that deliver to Canada, and budget alternatives for drivers who are not ready for a full replacement.
Why Your Factory Truck Mattress Needs to Go
Factory truck mattresses are built to a price point, not a comfort standard. They typically use 3-5 inches of low-density polyurethane foam (1.2-1.5 lb/ft3 density) with a basic vinyl or polyester cover. Compare this to a quality home mattress that uses 1.8-2.5 lb/ft3 density foam in 10-14 inches of layered construction.
Why this matters for health: Truckers already face elevated risks for back pain, obesity, and cardiovascular disease due to prolonged sitting. Research from the Journal of Chiropractic Medicine (Jacobson et al., 2008) shows that medium-firm mattresses significantly reduce back pain and improve sleep quality. The factory thin-foam mattress provides neither adequate support for spinal alignment nor sufficient cushioning for pressure relief, compounding the physical toll of driving.
Why this matters for safety: Fatigue is a factor in approximately 20% of commercial vehicle crashes in Canada (Transport Canada data). A mattress that delivers poor sleep means a driver who starts the next shift already compromised. Investing $500-$700 in a quality truck mattress is one of the most cost-effective safety upgrades a driver or fleet can make.

Sleeper Berth Mattress Sizes by Truck Model
There is no universal standard for truck mattress sizes. Before ordering, measure your bunk's width, length, and maximum thickness (the clearance between the bunk surface and the ceiling or upper bunk).
| Truck Make/Model | Common Mattress Size | Industry Size Code |
|---|---|---|
| Freightliner Cascadia | 36" x 80" or 42" x 80" | Size A or Size C |
| Kenworth T680 | 38" x 80" or 42" x 80" | Size B or Size C |
| Peterbilt 579 | 36" x 80" or 42" x 80" | Size A or Size C |
| Volvo VNL 760/860 | 36" x 80" or 42" x 80" | Size A or Size C |
| Mack Anthem | 36" x 80" | Size A |
| International LT | 36" x 80" or 42" x 80" | Size A or Size C |
| Western Star 5700XE | 35" x 79" or custom | Non-standard |
Critical: Always measure your actual bunk, not what the manufacturer spec sheet says. Aftermarket modifications, different cab configurations, and model-year variations can change dimensions by 1-3 inches. Measure width at both the head and foot (some bunks taper), and measure the maximum mattress thickness your clearance allows. Most truck mattresses are 7-9 inches thick, but if your upper bunk or ceiling clearance is limited, you may need a thinner option.
Best Truck Mattresses Available in Canada
Our Pick: Mattress Miracle High Density Fleet & Trucker Mattress (Brantford, ON)
Why we built our own truck mattress: After years of hearing from drivers and fleet managers about mattresses falling apart within a year, we decided to build something better. Our truck mattress uses a 1.7 lb/ft3 density foam core (custom builds) or 1.9 lb/ft3 (full builds), which is the same commercial grade used in hotel mattresses built for nightly guest use. Most truck mattresses on the market use 1.2 to 1.5 lb foam, which is why they sag and lose support so quickly.
- Flippable design with quilted comfort on both sides, effectively doubling the usable lifespan
- Reinforced edge support built for sleeper cab entry/exit
- Custom sizing available for all sleeper cab configurations
- Canadian-made and shipped direct across Canada
- Custom fleet pricing available for bulk orders

Best Canadian-Made: Sleep Boutique (Calgary, AB)
Sleep Boutique is one of the only Canadian manufacturers making truck-specific mattresses. Built in Calgary, Alberta, their semi-truck line ships across Canada with no cross-border duties or customs delays. Three models available:
| Model | 36" x 80" | 38" x 80" | 42" x 80" | Construction |
|---|---|---|---|---|
| Pit Stop | $449 CAD | $459 CAD | $495 CAD | Foam, practical entry-level |
| Long Haul | $479 CAD | $489 CAD | $559 CAD | Higher-density foam, built for daily use |
| R&R | $629 CAD | $675 CAD | $729 CAD | Premium comfort, latex or spring options |
Why Sleep Boutique: Canadian-made means no import duties, faster shipping within Canada, and CAD pricing. Custom sizes available for non-standard bunks. 120-day trial period. The Long Haul model at $479-$559 hits the best price-to-quality ratio for drivers who use their sleeper 200+ nights per year.
Best US Brand with Canada Shipping: SleepDog / BigDawg
SleepDog is the most recognized name in truck mattresses, recommended widely on r/Truckers and TruckersReport.com forums. Manufactured in the US and available through their website with shipping to Canada (expect duties and shipping surcharges). Two models:
| Model | 36" x 80" | 39" x 80" | 42" x 80" | Construction |
|---|---|---|---|---|
| SleepDog | $519 USD | $549 USD | $589 USD | 7" CoolRest gel memory foam, single-sided |
| BigDawg | $689 USD | $709 USD | $729 USD | 9" double-sided memory foam, flippable |
Why SleepDog: The BigDawg's double-sided design is ideal for truck use. When one side develops body impressions, flip the mattress for a fresh sleeping surface, effectively doubling the usable lifespan. DOT-approved, 120-day trial, 10-year warranty. The drawback for Canadian drivers: USD pricing plus shipping and potential duties add 30-40% to the sticker price.
Best Budget Option: Amazon.ca Foam Mattress + Cut to Size
Some drivers save money by ordering a standard Twin XL (38" x 80") foam mattress from Amazon.ca and cutting it to fit. A Zinus Green Tea Twin XL runs $230-$280 CAD. If your bunk is 36" wide, trimming 2 inches off one side with an electric carving knife takes about 15 minutes. This approach gives you 10 inches of foam for less than the price of a 7-inch truck-specific mattress.
Why DIY cut: Cheapest option by far. Works well for 38" and 42" bunks where Twin XL fits without cutting. The downside: standard mattresses are not DOT-rated for fire retardancy (which technically matters for commercial vehicles), and the warranty is voided by cutting.
Best Custom: Foamite (Ontario)
Foamite is an Ontario-based foam manufacturer that cuts custom mattresses to any dimension. Order a 36" x 80" x 6" or 8" high-density foam slab for $200-$400 CAD depending on foam type and thickness. Factory-direct pricing with no retail markup. They also offer latex and memory foam options. Shipping across Ontario is affordable; national shipping adds $50-$100.
Why Foamite: Factory-direct pricing is hard to beat, and custom sizing means perfect fit for non-standard bunks. No cover included (order a zippered mattress cover separately for $30-$50), but the foam quality is comparable to truck-specific brands at half the price.
Ontario truckers: If you are based in the Brantford or Hamilton corridor, visit Mattress Miracle at 441 1/2 West St to try mattress options before ordering a truck-specific size. We can help you determine the right firmness and thickness for your cab. Our Restonic models use similar pocketed coil technology to what premium truck mattresses offer. Call (519) 770-0001.

What Matters Most in a Truck Mattress
| Factor | Why It Matters for Truckers | What to Look For |
|---|---|---|
| Thickness | More foam = more support and pressure relief | 7-10 inches ideal; check bunk clearance |
| Foam density | Low-density foam compresses permanently within months | 1.8+ lb/ft3 for daily truck use |
| Temperature regulation | Sleeper cabs trap heat, especially in summer | Gel-infused foam or ventilated layers |
| Cover material | Needs to handle sweat, spills, confined space moisture | Removable, washable cover; avoid vinyl |
| Fire rating | DOT requires flame-resistant bedding in commercial vehicles | DOT-approved or inherently fire-resistant materials |
| Double-sided design | Extends lifespan by allowing flip when one side wears | BigDawg is the primary option |
| Edge support | Narrow bunks mean you sleep near the edge often | Reinforced edges or high-density foam perimeter |
Mattress Toppers: The Budget Alternative
If a full replacement is not in the budget right now, a quality mattress topper can dramatically improve your factory mattress for $80-$200 CAD:
Memory foam topper (2-3 inches): Adds pressure relief and cushioning on top of the factory foam. Look for gel-infused options to reduce heat buildup. $80-$150 CAD on Amazon.ca. Cut to fit your bunk dimensions with scissors or an electric knife.
Latex topper (2-3 inches): More responsive than memory foam, naturally cooler, and antimicrobial. $120-$200 CAD. Best for drivers who find memory foam too hot or too "sinky."
Egg crate foam (2 inches): The cheapest option at $30-$50 CAD. Provides basic cushioning and airflow. Will not last more than 6-12 months of daily use, but useful as a temporary improvement while saving for a real mattress.
A topper extends the usable life of a factory mattress by 6-12 months, but it does not fix the fundamental problem of insufficient support. Think of it as a bridge solution, not a permanent fix.
Fleet Buying Guide
Fleet managers equipping multiple trucks need to think beyond sticker price. The biggest factor in fleet mattress longevity is foam core density. Most suppliers use 1.2 to 1.5 lb/ft3 foam, which breaks down within a year of nightly use. Here are your options in Canada:
Premium Fleet Option: Mattress Miracle (Brantford, ON)
We build custom fleet mattresses with 1.7 lb/ft3 density cores (custom builds) or 1.9 lb/ft3 (full builds), flippable construction quilted on both sides, and reinforced edge support designed for sleeper cab use. According to the Sleep Foundation, low-density foam loses over five times more height after repeated compression than higher-density foam. Our builds use the same commercial-grade density found in hotel mattresses built for nightly guest use.
- Flippable design doubles usable mattress lifespan
- Custom sizing for all sleeper cab configurations
- Canadian-made, shipped direct to your terminal
- Volume pricing for fleet orders of any size
Email info@mattressmiracle.ca or call 519-770-0001 with your fleet size for a custom quote. Read our full foam density guide for fleet truck mattresses.
Other fleet suppliers in the Canadian market:
- Sleep Boutique: Offers fleet/bulk pricing on their website. Calgary-based, ships nationwide. Contact directly for quotes on 5+ mattresses. Standard foam density not published.
- SleepDog: US-based, offers fleet partnerships through Cota Systems. Volume discounts available for 10+ units. Ships to Canada. Uses standard truck mattress foam construction.
- Foamite: Ontario-based factory-direct. Low base pricing with additional discounts for bulk orders (10+ mattresses). Foam-only construction without coil support.
What to ask any fleet supplier: Before placing a bulk order, ask for the foam core density in lb/ft3. If they cannot tell you, or if the number is below 1.5, you are buying a mattress that will need replacing within a year. A quality fleet mattress should have a minimum 1.7 lb/ft3 core and ideally a flippable design.
Trucker Sleep Tips for Better Rest
A better mattress helps, but the sleeper cab environment matters too. These adjustments complement a quality truck mattress:
Temperature control: Idle-free APU (auxiliary power unit) systems or battery-powered cab climate systems maintain comfortable sleeping temperatures without running the engine. In summer, park nose-to-wind to improve natural airflow. Use a reflective windshield sun shade to reduce cab temperature.
Darkness: Invest in thick cab curtains or blackout panels. Light leaking around factory curtains disrupts melatonin production. A sleep mask ($10-$15) is the simplest backup solution.
Noise: Earplugs rated NRR 32+ or a white noise machine ($20-$40) mask truck stop noise. Some drivers use noise-cancelling earbuds designed for sleep.
Bedding: Use fitted sheets designed for truck mattress dimensions (available on Amazon.ca by searching "36x80 fitted sheet" or "truck mattress sheets"). A quality pillow and lightweight duvet make the sleeper feel more like a bedroom and less like a work space.
Routine: Maintain a consistent sleep schedule when possible. The body's circadian rhythm performs best with regular sleep and wake times, even when those times shift between day and night driving. Research from the Journal of Physiological Anthropology (Okamoto-Mizuno and Mizuno, 2012) confirms that consistent sleep environments improve sleep quality independent of schedule variability.
Frequently Asked Questions
What size mattress fits in a semi truck?
Most semi truck sleeper berths use mattresses between 32" x 80" and 42" x 80". The most common sizes are 36" x 80" (Size A) and 42" x 80" (Size C). However, there is no universal standard. Always measure your specific bunk's width, length, and maximum thickness clearance before ordering. Check both the head and foot width, as some bunks taper slightly.
Can I use a regular Twin XL mattress in my truck?
A standard Twin XL (38" x 80") will fit some truck bunks without modification (particularly 38-39" and 42" bunks). For narrower 36" bunks, you can trim 2 inches off one side with an electric carving knife. The main concerns are that standard mattresses may not meet DOT fire retardancy requirements for commercial vehicles, and the mattress warranty is voided by cutting. Despite this, many drivers use standard mattresses without issues.
Where can I buy a truck mattress in Canada?
Mattress Miracle (Brantford, ON) builds custom high-density truck mattresses with 1.7-1.9 lb foam cores and ships across Canada. Contact info@mattressmiracle.ca for individual or fleet pricing. Sleep Boutique (Calgary, AB) is another Canadian manufacturer of truck-specific mattresses, with prices from $415-$729 CAD and free shipping across Canada. Foamite (Ontario) offers custom-cut foam mattresses from $200-$400 CAD. US brands like SleepDog ship to Canada but add cross-border duties and shipping surcharges. Amazon.ca carries standard Twin XL mattresses that can be cut to fit, and Wayfair.ca has some truck-specific listings.
How thick should a truck mattress be?
7-10 inches is ideal for nightly use. The factory mattress in most trucks is only 4-5 inches thick, which is why it feels inadequate after a few weeks. Thicker mattresses provide better pressure relief and spinal support. Before ordering, measure the clearance between your bunk surface and the ceiling or upper bunk to ensure the thicker mattress fits. If clearance is limited, a 6-7 inch mattress with a 2-inch topper can work.
How long does a truck mattress last?
Longevity depends largely on foam core density. Most budget truck mattresses use 1.2-1.5 lb/ft3 foam and last 1-3 years at best. Higher-density builds (1.7 lb+) with flippable construction last significantly longer. Factory mattresses typically lose comfortable support within 6-12 months of regular use. Quality replacement mattresses with higher-density foam cores last 3-5 years with nightly use. The BigDawg's double-sided design can extend this to 5-7 years by flipping when one side develops impressions. Mattress toppers last 6-18 months depending on quality and frequency of use.
Do truck mattresses need to be DOT approved?
Technically, DOT and FMCSA regulations require flame-resistant materials in commercial vehicle sleeping areas. In practice, enforcement of mattress-specific compliance is rare during inspections. DOT-approved truck mattresses (like SleepDog and BigDawg) use inherently fire-resistant foam that meets FMVSS 302 standards. If you use a standard consumer mattress, be aware that it may not meet these standards, though many drivers do so without issues.
