Mattresses
A safe night's sleep starts with the right mattress. Bambi Baby's mattress collection covers every stage of childhood sleep, from breathable infant crib mattresses to twin and full mattresses for toddler and teen rooms, with firmness, fit, and airflow chosen for how babies and kids actually sleep.
Baby Crib Mattresses Built for Safe Sleep
A baby crib mattress has one job above all others: pair a firm, flat surface with breathable construction so your baby can sleep soundly and you can rest with peace of mind. Our crib mattresses meet standard US crib dimensions for a snug fit (no gaps along the rails), and many models offer dual-stage firmness, so the same mattress works for newborn sleep on one side and toddler comfort on the flip side.
Breathable Baby Mattress Options
Breathable baby mattress designs use washable, air-permeable covers and ventilated cores to promote airflow and reduce heat buildup, useful in warmer nurseries and for parents prioritizing breathability as a safe-sleep feature. Look for waterproof, wipe-clean covers and GREENGUARD Gold or CertiPUR-US certifications throughout the collection.
What's in the Collection

How to Choose a Crib Mattress
Three things matter most: firmness, fit, and breathability. The AAP recommends a firm, flat sleep surface for infants under 12 months, no soft toppers, no pillow tops. Fit is equally important: the mattress should sit snugly against all four sides of the crib with no more than two fingers of space at the edge. After that, look at the cover (waterproof and washable saves countless 2 a.m. sheet changes), the core (innerspring, foam, or natural fiber), and certifications like GREENGUARD Gold and CertiPUR-US for low-emissions materials.
When to Move Up a Size
Most crib mattresses with a toddler side carry a child through the transition to a toddler bed, usually somewhere between ages 2 and 3. From there, parents typically size up to a twin or full mattress as part of the bigger-room refresh, often alongside dadada toddler furniture or a convertible bed from Oxford Baby or Westwood Design.
Style the Rest of the Nursery
A crib mattress is one piece of a complete sleep setup. Pair it with organic cotton sheets and a waterproof pad, then build out the room with a glider for late-night feeds, see our motorized nursery gliders, and the rest of your baby gear over in Baby Gear.
Frequently Asked Questions
What's the safest mattress for a newborn?
A firm, flat crib mattress that fits snugly in a standard US crib with no gaps, paired with a fitted sheet and nothing else in the crib. Soft mattresses, pillow tops, and loose bedding are not safe for infants under 12 months.
How firm should a baby crib mattress be?
Very firm. Press your hand into the mattress, it should spring back immediately and not conform to the shape of your hand. Infant sides of dual-stage mattresses are intentionally firmer than the toddler side.
What is a breathable baby mattress?
A breathable baby mattress uses an air-permeable cover and ventilated core to allow airflow through the sleep surface, reducing heat retention. Many breathable models also have a fully washable cover.
Are organic crib mattresses worth it?
Organic mattresses use materials like organic cotton, natural latex, and wool instead of polyurethane foam, and avoid added flame-retardant chemicals. For parents prioritizing low-emissions materials and natural fibers in the nursery, they're a strong choice. Look for GOTS, GOLS, and GREENGUARD Gold certifications.
When should I replace the crib mattress?
Replace a crib mattress if the core sags, the cover tears, or the firmness changes. A well-made crib mattress typically lasts through one child and often into a second, especially with a waterproof mattress pad protecting the cover.
What size mattress comes after the crib?
It depends on the bed. Convertible cribs that turn into toddler beds usually keep the same crib mattress. From there, most families size up to a twin or full mattress when moving to a big-kid bed.
