- Place your baby on their back for every sleep, on a firm, flat surface in a crib, bassinet or play yard that meets CPSC safety standards.[1][2]
- On a dual-sided mattress, use the firm infant side for babies under 12 months. The softer toddler side is for older children.[1]
- Cover the mattress with a fitted sheet only, and keep pillows, blankets, bumpers and soft toys out of the crib.[1][3]
- No product, including any mattress, has been shown to prevent SIDS.[3][4]
The Right Kind of Support for Toddlers
Babies need a firm, flat mattress. The main reason is safety: a firm surface lowers the risk of suffocation.[1] Toddler beds are built around a standard full-size crib mattress, so the mattresses below fit both cribs and toddler beds.[5] Every crib mattress sold in the US must meet the federal crib mattress standard, 16 CFR 1241, which includes a firmness test.[6][7] An infant needs the firm side of a crib mattress, whereas a toddler can use a little more cushioning. Many dual-sided mattresses have a firm infant side and a slightly softer toddler side, so one mattress lasts from the crib to the toddler bed. A full-size crib mattress must be at least 27 1/4 inches wide and 51 5/8 inches long, and is generally no more than 6 inches thick.[6][8][9] If you can fit more than two fingers between the mattress and the frame, the mattress is too small.[10][11]
The two-finger test: if more than two fingers fit between the mattress and the crib side, the mattress is too small.[10][11]

Seen from above, the mattress should fill the crib with no gaps. Use a firm, flat mattress with a fitted sheet only.[1][10][11]
- Foam Crib Mattress – A foam mattress is light, which makes sheet changes easier, and foam is usually cheaper to buy. Many have a waterproof cover. Foam is also used in many twin mattresses for kids.
- Innerspring Crib Mattress – an innerspring crib mattress has coils inside, like an adult mattress, with a layer of cotton, wool, fiber or foam on top. It is usually heavier than foam.
- Fiber Crib Mattress – some mattresses use a fiber or polymer core instead of foam or coils. All types must pass the same federal firmness test.[7]
Risks Associated with Purchasing a Toddler Mattress
There are two main risks to know about when you buy a mattress for your baby or toddler. If you are a parent, you need to know these safe-sleep facts.- Sudden Infant Death Syndrome (SIDS) – SIDS is the sudden, unexplained death of a baby under 1. The cause is not known, and no mattress or other product has been shown to prevent it.[3][4] What lowers the risk is a safe sleep setup: always place your baby on their back, on a firm, flat mattress with a fitted sheet only.[1]
- Suffocation – never put a baby on a memory foam topper or any soft surface that lets them sink in. Soft surfaces and soft bedding can block a baby’s breathing. A firm, flat mattress that fits the crib with no gaps helps prevent suffocation and entrapment.[1][10]

Toddler Mattress Qualities to Look For
Here are some useful toddler mattress features.- Organic and Certified Materials – organic cotton or wool covers are popular, and labels such as GREENGUARD Gold, CertiPUR-US and GOTS tell you what was tested.[12][13][14] These are not general safety ratings.[12][13][14] If your child has allergies, ask your pediatrician.
- Waterproof – A waterproof crib mattress is very useful, especially if your little one is quite the mess maker! Many can be wiped down with a damp cloth.
- Removable Cover – A removable, washable cover makes cleaning much easier and keeps the mattress in good condition. Follow the maker’s care label.
- GREENGUARD Gold (UL Solutions): the product meets strict limits for chemical emissions (VOCs) into indoor air.[12]
- CertiPUR-US: the foam is made without formaldehyde, ozone depleters, CPSC-regulated phthalates, mercury, lead and other heavy metals, and has low VOC emissions.[13] It covers the foam, not the whole mattress.[13]
- GOTS: textiles made with certified organic fibres and processed under GOTS criteria.[14]
- OEKO-TEX STANDARD 100: the textile was tested for a list of harmful substances.[15]
Our Toddler Mattress Picks
How we chose these toddler mattresses
We did not test these mattresses ourselves. We compared them using the research steps on our How We Research page:- Federal size and firmness rules: every mattress here is a full-size crib mattress that also fits standard toddler beds.[6][8]
- Certifications checked where possible: when we confirmed a certification in the certifier’s database, we give the certificate number; otherwise we write “the manufacturer says”.[12]
- Recall check: we searched the CPSC recall database for each brand and model.[10]
- Availability: each mattress was listed as in stock on Amazon when we last checked (October 2026).
1
- Best for: parents who want a lightweight, dual-sided fiber-core mattress on a budget.
- This mattress is sold by Delta Children under the Serta brand name.
- According to the manufacturer, it has a firm side for infants and a toddler side with an extra comfort layer.
- It is GREENGUARD Gold certified for low chemical emissions (UL certificate 301526-420).[16][12]
- The manufacturer says the fiber core is made from recycled plastic bottles and lists the size as 52 x 27.5 x 5.5 inches, for standard full-size cribs and toddler beds.
- Trade-off: the core is synthetic polyester fiber, and the toddler side adds only a thin comfort layer.
2
- Best for: parents who want a light, plant-based foam mattress with a wipe-clean cover.
- According to the manufacturer, it has a firmer infant side and a toddler side with a soy-enhanced foam topper.
- The soy-enhanced foam is still polyurethane foam; this mattress is not organic.
- The manufacturer says the foam is CertiPUR-US certified.[13]
- It is GREENGUARD Gold certified for low chemical emissions (UL certificate 20929-420, model EM710).[17][12]
- The manufacturer lists the size as 51.63 x 27.25 x 5 inches, for standard full-size cribs and toddler beds.
- Trade-off: the cover is vinyl-type waterproof material rather than organic cotton.
3
- Best for: parents who prefer a traditional coil mattress with an extra-firm infant side.
- According to the manufacturer, it has 204 steel coils, a perimeter border wire and steel support bars.
- The manufacturer says the infant side is extra firm and the toddler side is softer.
- It is GREENGUARD Gold certified for low chemical emissions (UL certificate 21204-420).[18][12]
- The listing describes a medical-grade waterproof cover that wipes clean.[19]
- Trade-off: the vinyl cover can feel crinkly, and coil mattresses are heavier than fiber-core ones.
4
- Best for: parents who want a mattress they can wash down to the core.
- The manufacturer says the core is about 90% air and 10% food-grade polymer, with no foam, latex or springs.
- According to the manufacturer, the cover is machine-washable and the core can be rinsed in a shower or tub.
- It is GREENGUARD Gold certified for low chemical emissions (UL certificate 67431-420).[20][12]
- A breathable core can feel cooler, but no mattress has been shown to lower SIDS risk; place your baby on their back on a firm, flat surface with only a fitted sheet.[3][4]
- Trade-off: it costs more than most fiber-core and foam mattresses, and the standard cover is not waterproof.
5

6
