Choosing a crib mattress for baby is not usually considered much important, but it is actually of much more importance, as your newborn baby needs a certain level of comfort and you also want to ensure child safety in bed. A baby usually spends much of his time in bed; a normal baby sleep is about 18 hours. The importance of choosing a good mattress increases when we consider the fact that a crib mattress may be used by baby for up to three years of age. It has shown that there are several factors which need to be considered while you prepare to shop for a baby crib mattress.

Things to consider:

  • Mattress size
  • Comfort & Firmness
  • Mattress type
  • Ventilation
  • Mattress cover
  • Quality & Certification

Things to avoid:

  • A used crib mattress
  • Worrying about warranty

While one needs to keep these things in mind while buying a crib mattress. We tend to look each of them in detail to help you in buying just the right stuff for your lying on a crib mattress

Mattress Size:

This is one of the best and most important things to be considered while buying a mattress.  As this directly connects to the safety of the child. The size of the mattress should neither be too big nor too small. It’s better to buy the crib first so that you can have the exact measurement of the mattress to be bought. A typical standard size of a mattress is 27 1/4 inches by 51 5/8 inches with 6 inch thickness.

If standard size is followed for both crib and mattress, it’s convenient, but one should still check the fit of the mattress in crib along with a mattress cover. There shouldn’t be any gap between the mattress and walls of the crib. This can be checked by inserting your fingers on sides after putting the mattress into the crib. Any gap poses a serious threat to the baby safety, and such mattress should be replaced with a precisely sized mattress.

Comfort & Firmness:

You should consider the comfort level of the mattress as this is certainly linked to a healthy sleep of the baby. The crib mattress should be adequately firm for the baby to feel comfortable on it. It shouldn’t be too much stiff or too soft. Mattresses for babies tend to be slightly more firm than those of adults or older children, so it’s quite normal. A better way to check firmness is by pressing it with your hands; it shouldn’t get to the shape of your hands and restores to its original form in the crib

Mattress Type:

Available varieties are foam, spring and organic mattresses. Foam mattresses are a good choice as they are relatively budget-friendly, the spring type is suitable for durability, comfort and baby safety but is expensive than the foam counterparts.

Organic mattresses are also durable and safe but expensive too. So it’s your choice to select the best among the available options until the safety requirements of baby and your budget limits are met.


This is also one of the essential points to be checked. There are vents in mattresses to ensure that mattresses “breathe.” This refers to the possibility of getting the air crossed through the mattress and baby can breathe in case his face is pressed up against the mattress.

Mattress Cover:

The mattress cover is essential and better if its water and tear proof. A removable and washable cover makes sure the cleanliness and health of the baby and also convenience for the crib mattress cover

Quality and Certification:

An important aspect to consider is the mattress quality, and one should go for certified quality endorsements preferably from independent bodies. As this not only ensures quality but also makes sure that all the safety and other standards related to infants are met.

Looking for an Oeko-Tex Standard 100 certification is helpful as this is a global certification for making sure that certain flame retardants and heavy metals are not used in mattress manufacturing.

While considering the already discussed points when preparing to buy a baby crib mattress, you should also make sure to avoid a couple of things as we talk next.

Avoid buying a used crib mattress:

A used mattress is shown to be linked to sudden infant death syndrome (SIDS) or suffocation. According to, the used mattresses can also be harmful as they may be infected with mold, bacteria or fungus. At the same time they can also be a source of allergies and respiratory problems. So instead of saving a few bucks and buying a thing which may pose a hazard to your child, it’s better to buy a new mattress.

Worrying about warranties:
