As soon as your baby arrives, you are going to notice significant changes around your home. You will buy several things to accommodate your newborn bundle of joy as well as get rid of a few items. Furthermore, one of the things that have significant importance in baby gear items is a crib, and to use a crib properly, we need a crib mattress. Choose the right mini crib mattress can is a major decision and requires you to consider a lot of factors, which can be a little overwhelming. Additionally, the right crib mattress is not only vital for the décor of your nursery, but it also ensures the safety of your child. 

After purchasing a baby crib, all you have to do is buy a mini crib mattress that fits the crib perfectly. The correct size of the crib mattress is crucial for your baby’s safety, and you have to make sure that the crib mattress doesn’t leave any gaps between the crib frame and the mattress’s edge. Furthermore, to be on the safe side, the space between the frame and the crib mattress shouldn’t be more than two fingers. You can also check this by trying to fit two fingers in that gap between the crib mattress and the frame.

Additionally, while choosing a crib mattress, make sure that it follows federal regulations regarding its dimensions, material, and quality to ensure the safety of your child. According to a study, about 3,500 babies in the United States die every year due to unsafe sleep environments. Similarly, the wrong crib mattress can lead to strangulation, entrapment, and suffocation, which can cause Sudden Infant Death Syndrome (SIDS). 

Features to Consider in a Crib Mattress

When you are about to purchase a new crib mattress for your child’s crib, there are a few factors that you should consider so that you make the right choice. Let’s discuss some of these features.

Mattress Firmness

The ideal crib mattress should be firm instead of soft and cozy. While your older child might like using a snug, comfortable crib mattress, but for infants, the American Academy of Pediatrics recommends using a firm mattress for their ultimate safety. However, ‘firm’ doesn’t necessarily mean rock hard; a mattress should be firm enough to prevent your baby’s head from sinking in and, as a result, minimizing the suffocation risk.

Furthermore, you can test the firmness of a mattress by pressing its center and edges, and it should snap back into its natural shape as soon as you release it. Additionally, if the mattress conforms to the shape of your hand, then it is too soft for the baby.

Mattress Depth

The depth of a mattress has nothing to do with its firmness, and it depends on you to choose the wanted thickness. Spring-coil mattresses are usually five to six inches deep and are thicker than foam mattresses that are four to six inches thick. Furthermore, foam mattresses, other than memory foam mattresses, don’t weight as much as spring mattresses, which also makes it easier to lift them when you are changing sheets or for crib cleaning purposes.

Additionally, if you want a thick spring mattress, the more the layers and the better quality of those layers, the thicker the crib mattresses. However, the increased number of layers and better-gauge steel for coil springs will increase the weight of your spring mattress. Also, if the cushioning is of good quality, that would add more weight to the spring mattress.

Mattress Weight

Experts recommend using lightweight crib mattresses because they are easier to lift. Since you have to clean the mattress sheets frequently, ideally twice every week, you will need to remove the crib mattress often, and a bulky mattress will make this task more exhausting.


In foam mattresses, foam is the material used for cushioning. However, if you are purchasing a spring mattress, you have several options available, such as foam, cotton, and polyester. Furthermore, foam and cotton provide the highest quality of cushioning, as well as they are expensive. On the other hand, polyester is a less expensive option and commonly used.

Additionally, to be on the safe side, don’t purchase a mattress unless you what material it is made of. You can check the details on the tag or on the website of that brand.

The breath-ability of a mattress is essential because the lack of it can cause suffocation, which can lead to Sudden Infant Death Syndrome. A breathable mattress allows proper ventilation and to flow through the crib mattress freely. This way, the crib mattress doesn’t heat up, and the temperature remains under control to ensure a safe sleep environment for your child.

Duration of Use

Some crib mattresses have two types of sides, one side is firm, which is ideal for infants, and the other side is slightly softer, which is suitable for toddlers so that they can enjoy a cozy sleep. Furthermore, these crib mattresses are also known as two-stage mattresses, and they feature a mark on both sides so you can easily recognize which side is which.

Additionally, these types of mattresses serve you for a long time. However, you should discuss with your health care provider to find out when it is safe to flip the crib mattress so that your child can enjoy the cozy side of it.


All mattresses come with either fabric or vinyl covers that surround the entire crib mattress. Fabric covers are more breathable in comparison to vinyl covers; however, if a vinyl cover has ventilation holes, they can help with air circulation in the mattress. Furthermore, if you go for a multilayered vinyl cover, it will extend the duration of use of your crib mattress because multiple layers protect a crib mattress from punctures, leaks, spills, and stains.

On the other hand, fabric covers cannot prevent a crib mattress from spills and stains.  Additionally, look for three-layered or three-ply mattress covers as they will provide a safer shield, which will maximize the durability of the mattress.
