A crib mattress has to fit the crib snugly, so size matters more here than with any adult bed. Most are about 52 by 27.5 inches, and many are dual-sided, with a firmer side for infants and a softer one for toddlers. The main choices are foam or innerspring, the cover, and the certifications the maker lists.
The six mattresses below are sized for a standard crib. Dimensions, weights and certifications come from each product’s listing page. We have not used these mattresses ourselves and make no safety claims; every safety statement is the maker’s own. Always check the crib maker’s guidance on mattress fit and follow current safe-sleep advice from your pediatrician.

Setup and Care
- Let a boxed foam mattress expand for the time the maker states before use.
- Measure for gaps between the mattress and the crib frame; the maker’s guidance on fit applies.
- Use a fitted sheet made for crib mattresses.
- Wipe the surface and wash a removable cover as its label directs.
Mistakes to Avoid
- Buying a mattress without checking the crib’s size requirements.
- Relying on a certification as proof of safety.
- Adding soft extras that the safe-sleep guidance advises against.
- Putting the toddler side up before the child is ready.
Crib Mattress FAQ
Foam or innerspring?
Foam is lighter. Coils are heavier and often sold as a more traditional build. Both are on the market in standard crib sizes.
Can a crib mattress be used in a toddler bed?
Many are marketed that way, but check each mattress’s weight limit and the bed’s own guidance.
Does GREENGUARD Gold guarantee safety?
No. It is a certification about chemical emissions, and the maker supplies the claim.
The Short Version
For a light foam mattress, the TeQsli. For a two-stage foam design, the Babelio. For an infant-to-toddler foam bed, the Dream On Me. For a coil mattress, the Sealy. For the thickest foam, the Graco Ultra. For a long certification list on a foam core, the Graco Premium, after you confirm the size.
