Quick Answer: A standard crib mattress in Canada measures 51 5/8" x 27 1/4" (131 x 69 cm), must be firm enough that it springs back when pressed, and should fit snugly inside the crib with no more than two fingers of gap on any side. The best crib mattresses carry GREENGUARD Gold certification and cost between $65 and $500 CAD depending on materials.
For most Canadian families, a dual-sided foam or innerspring model in the $100 to $250 range offers the right balance of safety, comfort, and longevity. Health Canada recommends a firm, flat surface as the only safe sleep environment for infants under 12 months.

A crib mattress is the single most important purchase a new parent makes for infant sleep, and the rules around it are not a matter of opinion. In Canada, crib mattresses are regulated under the Canada Consumer Product Safety Act and the Cribs, Cradles and Bassinets Regulations (SOR/2016-152), which set strict standards for firmness, dimensions, fit, and even sleep-surface incline.
A crib mattress is a firm, flat infant sleep surface sized to fit a Canadian crib with a gap of no more than 30 mm on any side. At Mattress Miracle in Brantford, family owned since 1997, we have walked hundreds of new parents through their first crib mattress decision, and our team brings 40+ years in the mattress industry to how we talk about infant firmness.
The market has expanded a great deal, with newer categories like Wovenaire (Newton Baby), certified organic (Naturepedic), and dual-sided convertible mattresses joining the standard foam and innerspring options.
This guide covers Health Canada safety standards, the firmness threshold the research actually points to, the seven leading brands available across Canada in 2026 (Newton Baby, Naturepedic, Sealy, Graco, Safety 1st, Simmons Kids, IKEA PELLEPANSEN, Nook Sleep Pebble), the Newton Baby versus Naturepedic comparison most parents ask about, a 2025 Canadian study on mattress chemicals every parent should know about, and the safe sleep checklist endorsed by the Canadian Paediatric Society and the American Academy of Pediatrics.
Always consult your paediatrician for guidance specific to your child.
"Here is the honest version we give new parents in our Brantford showroom, and it is not the version that sells the most expensive mattress. For a baby, firm beats fancy every time. A $99 mattress that passes the firmness test and fits the crib with no gap is safer than a $450 mattress that is even slightly too soft or too small. Spend your money on a snug fit, a real firmness check, and a good waterproof cover. Save the premium budget for the twin mattress they will actually sleep on for ten years."
Brad Grose, founder, Mattress Miracle, family owned in Brantford since 1997, with 40+ years in the mattress industry
How firm should a crib mattress be for a newborn?
Firm enough that it barely indents. A peer-reviewed review of infant sleep-surface softness (Gillani, Lowell and Quinlan, Injury Epidemiology, 2021) documents a German death-scene investigation (Schlaud et al., 2010) in which a sleep surface that indented more than 14.5 mm under a standardized weight was significantly associated with Sudden Infant Death Syndrome, with an odds ratio of 4.4 (95% CI 1.1 to 8.7).
In plain terms: a mattress that sinks under light pressure carries measurably higher risk than one that stays firm. There is no formal paediatric number stamped on a mattress label, so the practical test below matters more than any marketing firmness rating. This information is educational, not medical advice.
Talk to your paediatrician about safe sleep for your child.

What are Health Canada's crib mattress safety standards?
In Canada, crib mattresses are regulated under the Canada Consumer Product Safety Act and the Cribs, Cradles and Bassinets Regulations (SOR/2016-152). These regulations set strict requirements for the entire sleep system, including how the mattress fits inside the crib and how flat the sleep surface must be.
What the research says
A 2019 study in Pediatrics on Sudden Infant Death Syndrome (SIDS) and sleep-related infant deaths found that 69% of sleep-related infant suffocation deaths were attributable to soft bedding. The study examined over 1,800 sudden unexpected infant death cases and found soft-bedding deaths occurred most often in an adult bed (49%) in a prone position (82%). Research suggests a firm, properly fitted crib mattress is not optional. It is essential. Always discuss your specific situation with your paediatrician.
Lambert AB, et al. Pediatrics. 2019;143(5):e20183408. DOI: 10.1542/peds.2018-3408Key Canadian requirements include:
- Snug fit: No more than 30 mm (about 1.2 inches) gap between the mattress and any side of the crib
- Firmness: The mattress must be firm enough to prevent suffocation. Health Canada warns against any sleep surface that conforms to an infant's face
- Thickness: The mattress must not exceed 15 cm (6 inches) in thickness for standard cribs
- Flat surface (the 7-degree rule): Health Canada prohibits infant sleep surfaces with an incline angle greater than 7 degrees. An inclined surface can let a baby slump into a position where they cannot breathe
- No soft materials on top: No pillows, blankets, bumper pads, or stuffed toys in the crib
The Canadian Paediatric Society and the American Academy of Pediatrics both recommend a firm, flat sleep surface with a fitted sheet as the only bedding for infants under 12 months. The Public Health Agency of Canada echoes this guidance in its Safe Sleep for Your Baby resource.
Recalls are not rare: check before you buy
The 7-degree incline rule has real teeth. In its 2023-2024 compliance project, Health Canada tested 16 cribs, cradles and bassinets and issued 6 recalls, 1 stop sale, and 5 stop-distribution orders.
Recent recalls and warnings have included bedside sleepers and bassinets whose surfaces tilted past the limit, such as the Angelbliss bedside crib (previously sold on Amazon.ca) and Peg Perego YPSI and Z4 bassinets with a headrest that inclined the sleep surface. The lesson we share with Brantford parents: a hand-me-down or marketplace find is not automatically legal.
Search the product on the Government of Canada Recalls and Safety Alerts database before your baby ever sleeps on it. For the snug-fit side of the rules, our crib mattress gap test guide for Canada walks through the two-finger check step by step.
What size is a standard crib mattress in Canada?
The standard crib mattress in Canada matches the U.S. standard, which is regulated by ASTM International under ASTM F2933. Here are the exact dimensions:
| Mattress Type | Length | Width | Max Thickness |
|---|---|---|---|
| Standard Crib | 51 5/8" (131.1 cm) | 27 1/4" (69.2 cm) | 6" (15.2 cm) |
| Mini Crib | 38" (96.5 cm) | 24" (61 cm) | 5" (12.7 cm) |
The two-finger test
Before you use any crib mattress, perform the two-finger test. Place the mattress inside the crib and try to fit your fingers between the mattress edge and the crib wall. If you can fit more than two fingers in the gap, the mattress is too small. This gap creates an entrapment hazard where an infant's face can become wedged.
Mini crib and cradle mattresses
Mini cribs are popular in Canadian condos and smaller homes where space is limited. They use a smaller mattress (38" x 24") and are ideal for newborns through about 18 months. If you choose a mini crib, make sure you buy a mattress specifically designed for it.
A standard crib mattress will not fit, and improvising with a cut-down mattress is dangerous. A cradle or bassinet mattress is smaller still and is matched to that specific product. The same rule applies to every size: the best cradle mattress is the one made for your exact frame, firm, and fitted with no gap, never a generic pad trimmed to size.
What are the different types of crib mattresses?
Crib mattresses fall into four main categories. Each has distinct advantages depending on your priorities: budget, breathability, chemical concerns, or longevity. If you are weighing the two most common options head to head, our guide to foam mattresses for cribs goes deeper on density and weight.
Foam crib mattresses
Foam is the most common crib mattress material and the most affordable. Most use polyurethane foam, though soy-based and plant-based options exist. A good foam crib mattress should weigh at least 3.5 kg (about 8 lbs) and have a density of at least 1.5 lb/ft3. The denser the foam, the firmer and more durable it will be.
Pros: Lightweight (easy to change sheets at 3 a.m.), affordable ($65 to $200 CAD), widely available
Cons: Can off-gas VOCs unless certified, may compress over time, less durable than innerspring
Innerspring crib mattresses
Innerspring crib mattresses use steel coils wrapped in foam and fabric. Look for a coil count of at least 135 with a wire gauge of 15.5 or lower (lower gauge means thicker, firmer wire). These mattresses tend to be heavier but last longer and maintain their firmness better than foam.
Pros: Superior airflow between coils, long-lasting firmness, often dual-sided (infant/toddler)
Cons: Heavier (5 to 8 kg), more expensive ($150 to $350 CAD), can be noisy with cheaper coils
Organic and natural crib mattresses
For parents concerned about chemical exposure, organic crib mattresses use materials like organic cotton, natural latex (Dunlop process), and organic wool. These mattresses avoid synthetic foams, chemical flame retardants, and vinyl covers. They cost more, but they address a real concern: infants spend 14 to 17 hours per day on their mattress, breathing air just centimetres from the surface.
Pros: No synthetic chemicals or flame retardants, naturally hypoallergenic, sustainable materials
Cons: Most expensive option ($300 to $500+ CAD), heavier, fewer choices available in Canada
Breathable/washable crib mattresses (Wovenaire)
Newton Baby pioneered this category with their Wovenaire core, a food-grade polymer woven into a structure that is 90% air and 10% material. The entire mattress, including the core, is machine washable. The big selling point: if a baby rolls face-down, they can still breathe through the mattress.
Pros: Fully breathable, machine washable, hypoallergenic, no foam or latex
Cons: Premium price ($350 to $450 CAD), lighter feel may seem unusual, only one brand offers this technology
What are the best crib mattress brands available in Canada in 2026?
Here is a comparison of the top crib mattress brands you can buy in Canada right now, with current pricing and key features. Any of these can be the right baby crib mattress depending on your budget and priorities:
| Brand/Model | Type | Price (CAD) | Certifications | Key Feature |
|---|---|---|---|---|
| Newton Baby Crib Mattress | Wovenaire | $350 to $450 | GREENGUARD Gold | 100% breathable, fully washable core |
| Naturepedic Organic | Innerspring/Organic | $400 to $500 | GOTS, GREENGUARD Gold, Made Safe | Certified organic cotton, no polyurethane foam |
| Sealy Soybean Foam-Core | Soy-based foam | $150 to $312 | GREENGUARD Gold | Soy-enhanced foam, 2-stage design |
| Graco Premium Foam | Foam | $65 to $100 | GREENGUARD Gold, CertiPUR-US | Best value, waterproof washable cover |
| Safety 1st Heavenly Dreams | Foam | $60 to $90 | GREENGUARD Gold | Budget-friendly, lightweight |
| Simmons Kids BeautyRest | Innerspring | $200 to $350 | CertiPUR-US | 231-coil count, dual firmness sides |
| IKEA PELLEPANSEN | Foam | $99 to $129 | OEKO-TEX Standard 100 | Affordable, available in-store across Canada |
| Nook Sleep Pebble | Natural latex | $400 to $470 | GREENGUARD Gold, GOLS | Organic latex, zinc-infused cover |
Newton Baby vs. Naturepedic: which premium crib mattress is worth it?
These two brands sit at the top of the crib mattress market, but they take fundamentally different approaches. Here is how they compare:
| Feature | Newton Baby | Naturepedic |
|---|---|---|
| Core Material | Wovenaire (food-grade polymer, 90% air) | Innerspring coils with organic cotton/wool |
| Breathability | 100% breathable through entire mattress | Standard breathability (surface vents) |
| Washability | Entire mattress is machine washable | Cover only (spot clean core) |
| Organic Certification | No (synthetic polymer) | Yes (GOTS certified organic) |
| Firmness | Firm with slight give | Very firm (innerspring) |
| Weight | 5 kg (11 lbs) | 8 to 10 kg (18 to 22 lbs) |
| Price (CAD) | $350 to $450 | $400 to $500 |
| Best For | Parents prioritizing breathability and easy cleaning | Parents prioritizing certified organic materials |
Bottom line: If breathability and washability are your top concerns (especially if your baby is a stomach roller), Newton Baby is the better choice. If avoiding synthetic materials entirely matters most and you want certified organic, Naturepedic wins. Both are excellent, safe options.
What crib mattress safety rules should every Canadian parent know?
What the research says
The American Academy of Pediatrics updated its safe sleep guidelines in 2022 after reviewing decades of evidence. The Canadian Paediatric Society advises the same approach: infants should sleep on a firm, flat surface free of soft bedding. The AAP found that a firm sleep surface reduces the risk of suffocation and rebreathing, where an infant breathes in their own exhaled carbon dioxide from a too-soft mattress that conforms to their face. If you have questions about safe sleep for your child, talk to your paediatrician.
Moon RY, et al. Pediatrics. 2022;150(1):e2022057990. DOI: 10.1542/peds.2022-057990Why firm is non-negotiable for infants
A crib mattress that feels too firm for you is exactly right for your baby. Adults prefer pressure relief because we have developed musculoskeletal systems. Infants have soft skulls, weak neck muscles, and cannot reposition themselves if their airway becomes blocked. A mattress that gives under their weight is a suffocation risk. This is the one area where the comfort instincts you trust for your own bed point you the wrong way. If you are still learning how a firm surface should feel, our plain-language explainer on crib mattress firmness is a good companion read.
Test firmness by pressing your hand into the centre of the mattress. It should spring back immediately. If your handprint lingers or the surface conforms around your hand, the mattress is too soft for an infant.
Never use memory foam for infants
Memory foam is designed to conform to body contours. That is precisely what makes it dangerous for babies. Health Canada, the Canadian Paediatric Society, and the AAP all advise against memory foam crib mattresses for infants under 12 months. The risk of facial impression and airway obstruction is too high.
The safe sleep checklist
- Firm, flat mattress that fits snugly in the crib (two-finger test)
- Fitted sheet designed for the specific mattress size. Nothing else in the crib
- No pillows, blankets, bumper pads, wedges, or positioners
- Sleep surface flat, never inclined more than 7 degrees
- Baby on their back for every sleep (the "Back to Sleep" position)
- Room temperature between 20 and 22 degrees Celsius
- No crib near windows, cords, or curtains
- Replace the mattress if it shows sagging, tears, or permanent body impressions
How do I choose a crib mattress for my priority (budget, organic, breathable)?
"Most parents who walk into our Brantford showroom for a crib mattress fall into one of three groups: budget-conscious, organic-focused, or worried about a stomach roller. We try to match the mattress to the worry, not the marketing. A $99 IKEA PELLEPANSEN with OEKO-TEX certification can be every bit as safe as a $450 premium model, as long as it passes the firmness test and the two-finger fit test."
Dorothy Balicki, Mattress Miracle
Best budget crib mattress
The Graco Premium Foam Crib Mattress is the clear winner at $65 to $100 CAD. It carries GREENGUARD Gold and CertiPUR-US certifications, has a waterproof machine-washable cover, and won the 2025 Parent Tested Parent Approved seal. For most families, this mattress covers all the safety essentials without the premium price.
Best organic crib mattress
The Naturepedic Organic Crib Mattress ($400 to $500 CAD) is the only crib mattress with GOTS organic certification, Made Safe certification, and GREENGUARD Gold. It uses no polyurethane foam, no vinyl, and no chemical flame retardants. The organic cotton cover and organic wool fire barrier make it the gold standard for parents who want zero synthetic materials touching their baby.
Best breathable crib mattress
The Newton Baby Crib Mattress ($350 to $450 CAD) is the only fully breathable, fully washable crib mattress on the market. Its Wovenaire core allows airflow from every direction. If your baby tends to roll onto their stomach, this mattress offers peace of mind that no other design can match.
Best for Canadian availability
The IKEA PELLEPANSEN ($99 to $129 CAD) is available at every IKEA location in Canada, which means you can see it and test it in person. It carries OEKO-TEX Standard 100 certification, and IKEA's return policy gives you time to ensure it fits your crib properly.
Do I need a waterproof crib mattress protector?
A waterproof mattress protector is not optional when you have an infant. Between diaper leaks, spit-up, and the inevitable nighttime accidents, your crib mattress will face more moisture than any other mattress in your home. If you want the full rundown on materials and fit, see our dedicated guide to a waterproof mattress for a crib.
Look for protectors that are:
- Waterproof on the top surface (not just water-resistant)
- Breathable to prevent overheating
- Fitted with elastic edges (loose protectors are a suffocation hazard)
- GREENGUARD Gold or OEKO-TEX certified to limit chemical exposure
Some mattresses, like the Graco Premium and IKEA PELLEPANSEN, include waterproof covers built in. For mattresses without one, a separate protector costs $20 to $50 CAD. Buy two so you always have a clean one ready during middle-of-the-night changes.
Should I use a crib mattress liner?
A crib mattress liner sits between the mattress and the fitted sheet, adding a layer of protection against stains and moisture while also providing a softer feel. Unlike a waterproof protector, a liner is designed primarily for comfort and stain prevention rather than complete waterproofing.
For infants, prioritize waterproof protection over liner comfort. After 12 months, when your child transitions to the toddler side of a dual-firmness mattress, a breathable cotton liner can add comfort without compromising safety.
When should I switch from a crib to a toddler bed?
Most children transition from a crib to a toddler bed between 18 months and 3 years. The right time depends on your child's development, not a specific age. Watch for these signs:
- Climbing out of the crib: This is the most urgent signal. Once a child can climb over the crib rail, the crib is no longer safe. A fall from crib height can cause serious injury
- Height: When your child reaches 90 cm (35 inches) tall, most cribs are no longer safe even with the mattress at its lowest position
- New sibling: If another baby needs the crib, transitioning the toddler makes practical sense
- Interest: Some children simply want a "big kid bed" and the motivation helps smooth the transition
Dual-sided crib mattresses: built for the transition
Many crib mattresses now offer a dual-sided design: one firmer side for infants and one slightly softer side for toddlers. When your child transitions from crib to toddler bed, you simply flip the mattress. This saves you from buying a separate toddler mattress and ensures continuity in your child's sleep environment.
Brands offering dual-sided designs include Sealy (Soybean 2-Stage), Simmons Kids (BeautyRest Beginnings), and Graco (Dual-Comfort Premium).
Toddler mattress sizing
Good news: a standard crib mattress fits a standard toddler bed. The dimensions are identical (51 5/8" x 27 1/4"). This means if you bought a quality dual-sided crib mattress, it will work in the toddler bed frame without buying anything new. Many convertible cribs transform into toddler beds using the same mattress. For a complete look at each stage from bassinet through toddler bed, see our baby bed guide for Canadian families.
When should my child move to a twin mattress?
When your child outgrows the toddler bed (usually between ages 3 and 5), a twin mattress is the next step. At Mattress Miracle in Brantford, we carry twin mattresses starting from $299 that use the same CertiPUR-US certified foams found in premium crib mattresses. This ensures your child's sleep surface remains free of harmful chemicals as they grow.
Visit our Brantford showroom at 441 1/2 West Street to test kids' mattresses in person. We can help you find the right firmness for your child's age and weight.

What do crib mattress certifications actually mean?
Certifications on crib mattresses can be confusing. Here is what each one actually tests for:
- GREENGUARD Gold: Tests for over 10,000 chemicals and VOCs. The Gold standard (not just regular GREENGUARD) is specifically designed for children and schools. This is the most relevant certification for a crib mattress
- CertiPUR-US: Certifies that polyurethane foam is made without certain flame retardants, heavy metals, formaldehyde, and phthalates. Only applies to foam mattresses
- GOTS (Global Organic Textile Standard): Certifies that at least 95% of fibres are certified organic and that the entire supply chain meets environmental and social criteria. The gold standard for organic claims
- GOLS (Global Organic Latex Standard): The equivalent of GOTS but for natural latex. Ensures the latex is at least 95% organic
- OEKO-TEX Standard 100: Tests finished textiles for harmful substances. Less comprehensive than GREENGUARD Gold but still meaningful
- Made Safe: Screens products for known toxic chemicals, including chemicals not covered by other certifications. Particularly rigorous
What did the 2025 Canadian study find about mattress chemicals?
In April 2025, researchers at the University of Toronto published two peer-reviewed studies that made certifications feel a lot less optional. This is recent enough that most crib mattress guides have not caught up to it yet.
What the research says
A University of Toronto team led by Professor Miriam Diamond tested 16 newly purchased children's mattresses and measured the air in 25 young children's bedrooms in Toronto and Ottawa. They detected 21 semi-volatile organic compounds (including ortho-phthalates, flame retardants, and UV filters), with the highest concentrations in the air closest to the bed. When the team simulated a child's body heat and weight, chemical emissions rose substantially.
One mattress exceeded the Canadian regulatory limit for di-n-butyl phthalate, and the companion study reported a flame retardant (TCEP) that has been restricted in Canada since 2014. Phthalates and certain flame retardants have been linked in other research to hormone disruption and effects on the developing brain. The researchers urged manufacturers to do better, and they advised parents to keep bedding minimal and wash it often.
This is educational context, not a diagnosis or medical advice. Speak with your paediatrician about any specific concern.
Bujak G, et al. (Diamond ML, senior author). Are Sleeping Children Exposed to Plasticizers, Flame Retardants, and UV-Filters from Their Mattresses? Environmental Science & Technology. 2025;59(16):7909-7918. DOI: 10.1021/acs.est.5c03560What this means in practice for a Canadian parent shopping in 2026: a third-party certification is the simplest way to skip this whole worry. GREENGUARD Gold tests for thousands of VOCs against limits set for children, and GOTS or Made Safe go further on organic and toxic-chemical screening. The study is also a strong reason to follow the safe-sleep basics that reduce exposure anyway, a fitted sheet and nothing else, a well-aired room, and regular washing. You do not need to panic-replace a mattress your child already sleeps on, but if you are buying new, certification is cheap insurance.
Are sleep sacks safer than blankets for infants?
Yes. Since blankets are not safe in cribs, sleep sacks (also called wearable blankets) are the recommended way to keep your baby warm. The Canadian Paediatric Society advises that loose blankets should never be used with infants under 12 months. Brands like Kyte Baby have become popular in Canada for their bamboo sleep sacks, which regulate temperature naturally.
When choosing a sleep sack:
- Select a TOG rating appropriate for your room temperature (0.5 TOG for warm rooms, 1.0 for average, 2.5 for cooler rooms)
- Ensure the neck opening is snug enough that the baby cannot slide down inside
- The armholes should be fitted, not loose
- Transition to a toddler sleep sack with foot openings when your child starts walking
What should you never add to a crib mattress?
Many of the suffocation hazards in infant sleep come from accessories well-meaning parents add to a perfectly safe crib setup. The Canadian Paediatric Society is unambiguous: nothing should go in the crib except the baby, the firm mattress, and a fitted sheet.
Never add to a crib mattress:
- A mattress topper or foam pad. A topper softens the surface and defeats the firmness that prevents SIDS. A baby's face can sink into a topper and obstruct breathing. There is no safe way to use a topper on a crib mattress.
- A memory foam mattress. Memory foam contours to the body, including a baby's face. The Canadian Paediatric Society and American Academy of Pediatrics recommend firm, flat surfaces only. Save memory foam for adult beds.
- Pillows, quilts, comforters, or stuffed animals. All are suffocation hazards under 12 months. Use a sleep sack instead of blankets.
- Crib bumpers (mesh, padded, or vertical). Health Canada has warned against bumpers since the 2010s. Health Canada Recalls and Safety Alerts has documented entrapment and strangulation incidents.
- Sheepskin or fleece "comfort layers." Same suffocation risk as a topper, plus overheating risk.
Used crib mattresses: a real risk. A 2002 study published in the BMJ (Tappin et al.) found a statistically significant association between previously-used infant mattresses and SIDS risk. The proposed mechanism is microbial growth from previous use. The Canadian Paediatric Society advises buying a new crib mattress for each baby. If you must use a hand-me-down, it should come from your own previous baby and be in clear, undamaged condition with intact waterproof cover. Talk to your paediatrician if you have any concerns about second-hand sleep equipment.
What are crib mattresses called in Quebec?
Quebec retailers list crib mattresses as "matelas de bassinette" or "matelas pour lit de bébé". The dimensions, safety regulations (SOR/2016-152), and firmness requirements are identical to the rest of Canada. Quebec-made options include Polysleep (Montreal) and Bleu.eco Bébé.
- Matelas de bassinette: Standard crib mattress (most common Quebec term)
- Matelas pour lit de bébé: Crib mattress (used by Babies R Us QC)
- Matelas pour berceau: Cradle mattress (smaller, for cradle/bassinet)
- Matelas pour couchette: Cot or play-yard mattress
Frequently Asked Questions
What is the best crib mattress for a newborn?
For a newborn, the best crib mattress is a firm, flat one that fits the crib snugly with no more than two fingers of gap and carries a children's certification like GREENGUARD Gold. Firmness matters more than brand or price: research summarized in Injury Epidemiology links sleep surfaces that indent more than 14.5 mm to higher SIDS risk. A well-rated foam model in the $65 to $150 CAD range, such as the Graco Premium Foam, covers the safety essentials for most Canadian families. Always confirm safe sleep practices with your paediatrician.
What size is a standard crib mattress in Canada?
A standard crib mattress in Canada measures 51 5/8 inches long by 27 1/4 inches wide (131 x 69 cm). The maximum thickness allowed is 6 inches (15 cm). A mini crib mattress measures 38 inches by 24 inches (97 x 61 cm). Always verify that your specific crib model accepts a standard-size mattress before purchasing.
Is Newton Baby crib mattress worth the price?
Newton Baby is worth considering if breathability and washability are top priorities. Its Wovenaire core allows babies to breathe through the mattress surface, and the entire mattress is machine washable. At $350 to $450 CAD, it costs 3 to 5 times more than a basic Graco foam mattress, but no other crib mattress offers full breathability and washability. For parents anxious about stomach sleeping, the peace of mind alone may justify the cost.
Can I use a memory foam mattress in a crib?
No. Health Canada, the Canadian Paediatric Society, and the American Academy of Pediatrics all recommend against memory foam for infants. Memory foam conforms to body shape, which creates a suffocation risk when a baby presses their face into the surface. Only use a firm, flat crib mattress for children under 12 months. Some dual-sided mattresses include a slightly softer (but still firm) toddler side with memory foam characteristics for children over 12 months. Always check with your paediatrician if you are uncertain.
When should I replace a crib mattress?
Replace a crib mattress if it shows visible sagging, permanent body impressions, tears in the cover, or if the foam no longer springs back when pressed. If using a second-hand mattress, check for any recalls and ensure it meets current Health Canada regulations. The safest option is always a new mattress for each child, as older mattresses may harbour bacteria, mould, or have degraded materials that affect firmness.
What is GREENGUARD Gold certification?
GREENGUARD Gold is a third-party certification that tests products for over 10,000 chemicals and VOCs (volatile organic compounds). The Gold level uses stricter limits than standard GREENGUARD and is specifically designed for sensitive individuals like children and the elderly. For crib mattresses, this certification means the mattress has been independently tested for off-gassing of formaldehyde, phthalates, and other harmful chemicals. Look for the actual GREENGUARD Gold mark, not just a brand claiming "low VOC."
