Now you know why should you increase the height of the crib mattress, and you already know that it is totally safe to increase the height of the crib mattress.

Step 1: Inspect the crib & mattress 

You have to check the baby’s crib, double-check the crib whether it is clean and ready to use with the mattress or not.

To ensure the comfort of your baby please make sure you use a breathable mattress.

After then remove the mattress to see if the support platform is enough to keep the mattress stays in place.

If the mattress is already in place then you can choose several options to start elevating the crib mattress.

Step 2: Elevate the Mattress

Using Pillow

You can put a pillow underneath the mattress to have it elevated, so consider a soft pillow placed under the head side of the crib mattress.

And then you have to examine the sides of the crib if it is securely covered with the bedding.

The middle part of the mattress should not sag, make sure the mattress stays in its position.

Using a blanket or a comforter

Another way to increase the height of a crib mattress is by using soft blankets or comforters.

You can fold them and place them underneath the head side of the crib mattress, making sure that the desired elevation is attained.

Also, evaluate if it would help ease the baby’s discomfort while sleeping.

Using Towels

Another effective way to increase the height of the crib mattress is to use towels to evaluate the crib mattress.

So roll the towels and place them underneath the head of the crib mattress and check if the elevation is offer comfort to the baby or not.

Using Books

You can use books on each head side of the mattress, phone books of the same size can also do the job.

But it’s very important that these objects are placed under the mattress not inside the crib with the baby.

Step 3: Adjust the Crib

If the options I presented above don’t work, then consider the idea of adjusting the crib itself, so measure the crib first, and make sure the adjustment is based upon the growing baby’s size.

For elevating the baby’s head, a couple of notches lower is recommended until a 30-degree angle is achieved.

One way is to remove the wheels at the bottom of the crib.

A solid support such as wood blocks must be placed underneath the legs below the head side of the crib.

So you just need to consider the height of the crib first, so increase the height to 5 to 6 inches. (you can adjust this height by your preference).

And after the height adjustment makes sure the crib mattress should suit the baby properly.

The elevation must be only a few inches utmost otherwise the crib will be unsafe for the baby.

And lastly, an important thing to remember check the crib frequency if it is secure and stable after the modification is done to avoid falls or accidents.


Elevating your crib mattress will be best for your baby, so if know how to make crib mattress higher then you can easily raise the mattress.

My personal advice to you is to ask doctors if they say okay to elevate the mattress then raise the crib mattress higher, take some advice from professionals.
