Buying Guide for Picking the Best Baby Crib Mattress in 2021:

Here are a few things you should consider while choosing a mattress for baby crib.

Right Size

Most of the crib mattress comes with standard size and fit on the normal crib or toddler beds. But if you have slightly different dimensions of your crib, then make sure you choose the right size.

A mattress should snugly fit inside the crib to remain perfectly safe for the baby.



Safety is the first thing you want to ensure whenever you buy something for your newborn.

The AAP has clear recommendations when it comes to creating a safe environment for the baby’s sleep.

The material of the mattress is important. Babies should not be laid on a soft mattress that bends with their weight. Soft mattress under babies is one of the major causes of SID in infants.

So the mattress should be firm under baby. It should be comfortable but should not bend at all with the baby’s weight. Too dense foams are a big no for babies.

Make sure you choose a mattress that complies with all safety measures for your baby.


Being firm does not mean the mattress cannot be comfortable. After all, you want to provide a perfect bed to your baby, so he can get quality sleep and wakes up in a pleasant mode.

Therefore, choose a mattress that combines all qualities. It should provide support underneath the baby, stays firm,  and is comfortable as well.


The material of the mattress is important. Babies have very soft and sensitive skin. You don’t want them to be exposed to chemicals. 

So the material of mattress should be medical grade foam that is woven with special layers to remain comfortable for the baby.

Too flimsy material will start tearing soon. And that may pose a big choking hazard for the baby. So investing in good quality material is important.

Not only the material of mattress is important, but you should also give a thought to the mattress cover. It should be soft on touch and soothing for the baby.

Water and Stain Resistant

Babies are messy most of the time. Make sure the mattress is at least wrapped in a water-resistant material. Now the water-resistant material should not be plastic at all.

If the moisture leaks inside the mattress, it will be of no use at all. It can make it smelly as well. So invest in a mattress that is stain and water-resistant.

Easy to Clean

You can wash the outer cover but cannot wash the foam inside.

 Make sure it has an out cover that can be cleaned from time to time. The cover should be easy to wash in a washer.

The fabric of the cover is also important as it will be touching the sensitive skin of the baby. Also, it should allow plenty of airflow inside the mattress to keep the foam odor-free.

Safety Measures

Make sure the material used in mattress and cover both are absolutely safe for the baby.

 Babies can wet the bedding and things can be messy. But selecting plastic sheets or covering is not safe for the baby’s skin as well. Make sure you choose the mattress that has safe covers so it won’t irritate the baby’s skin.

Using plastic is also not environmentally safe. It also has a very foul smell. So make sure you choose the material that does not emit any harmful chemical smell in the air.

Dual-side comfort

Babies grow very soon. The mattress should grow with your baby as well so that it remains useful as your baby outgrow this infancy stage.

Many mattresses come with dual sides to accommodate your growing needs. They feature a firm side for infants when babies need a solid base.

The other side of the mattress is more plush and soft. It is more comfortable. As the baby grows, you can turn the side of the mattress to make it more comfortable for the growing needs of your baby.

So the mattress remains useful for long as your baby turns into a toddler.

Non-toxin Material

Make sure you choose non-toxic material that remains soft on your baby’s skin.

Final Thoughts

Almost any baby crib mattresses you choose for the baby should be carefully selected. It should be free of toxins and chemicals.

The price range may differ depending on the safety features it comes with and the quality of foam used in the mattress.

 Make sure you invest in a quality product that remains useful for long.
