Buyer’s Guide

So, we have taken you through some of the best mattresses that you can currently buy for your little one.

However, there is an entire world of mini crib mattresses out there that we couldn’t hope to cover here, so you may want to keep searching.

If that is the case, make sure that you know what features are most important for you and your baby in your search, with this short guide.

The Right Fit/Size

This might seem obvious to some, but it is worth stating again that a good mini crib mattress needs to be the right size for the crib it is going to be placed in, snugly if possible there is a difference between mini crib vs crib mattress size.

This is to make sure that your child is at no risk of becoming trapped between the mattress and the crib.

Being the curious little souls that they are, babies and toddlers may try to move around their crib, and a mattress that allows for too much room between it and the crib can cause them to trap themselves and even suffocate, so make careful measurements before purchasing!


On the morbid subject of suffocation, you should also make sure that your mattress is made to allow airflow through the fabric and materials it is made from.

There is a risk that, even with a correctly fitted mattress, your baby finds that they cannot breathe well or easily if they are sleeping face down, as babies are notorious for moving in their sleep.

A mattress with good airflow will help mitigate this problem, allowing your baby to rest easier, regardless of what position they end up in.

It also has the added benefit of preventing a buildup of odors in your mattress, as a side bonus!

Water Proof

Let’s face it: At some point, your baby or toddler is going to end up having an accident while they are sleeping. And while they’ll probably be wearing diapers to bed, diapers can only do so much.

Because of this, the mattress that you purchase for the little one must have at least some amount of water resistance in some form.

Some mattresses have hydrophobic fabrics that they are made from, making them quite appealing to many parents.

However, this can also impact the softness of the mattress, so keep that in mind when purchasing.

Many other mattresses can be bought with covers to protect them instead, which also allows for easy removal and changing.


A mattress has to be comfortable for your child if they want to get a full nap or night’s sleep.

Memory foam mattresses, like our adult versions, can allow for a comfortable sleep, whilst also stopping your child from moving too much, helping keep their sleep peaceful.

Certified Non-Toxic

This is something that most, if not all, mattresses have to qualify for, so it shouldn’t be an issue when searching for a mattress made from non-toxic materials for your baby.

However, make sure that your mattress is certified by GreenGuard Gold, JMPA, or Certipur-US, as these are official organizations whose ratings can be trusted.
