cot bed mattress for 2021

For every parent, their little bundle of joy is the most important thing in the world. That’s why we’ve researched far and wide to help you find the best cot bed mattress on the market today. Most parents usually know what type of cot bed they want for the nursery, but the baby’s mattress is arguably the key purchase when it comes to getting the nursery ready.

With so many options out there, it can be overwhelming and worrisome for a new parent to select the right fit for their child. Babies and toddlers spend more time asleep than awake, which is why selecting a cot bed mattress for them is essential.

Babies spend between 13 and 16 hours per day sleeping. Do not worry about the decision making, as we are here to help! Here in LightSleeper, we test each product we review and thoroughly inspect it for a set number of days. However, we are non-professionals in the medical field, and these are only recommendations.

How to choose a cot bed mattress?

Next, we will try to help you with a few explanations and features that have to be taken into account before making a purchase. They are the following:


Selecting a base is something that can be beneficial for your baby as it grows. If you choose an adjustable option, you will typically find it with three positions.

Those positions can be switched with your baby’s growth. Every cot bed base will come with instructions, and in them, you can find the recommendations for the specific levels a set product offers. By selecting the appropriate base, you give your child a better chance at blissful sleep, and possibly a longer rest for yourself.


No matter if you choose a cot or a cot bed, you have to get the right type of mattress to go in it.

Even if you’re using a second-hand base, we recommend that you buy a new mattress so that you can make sure its dust free and hypoallergenic. You should look for a product that is on the firmer side and fits your bed with no gaps.

Usually, mattresses and cot beds are sold separately, which gives you the choice of different types. If you don’t know what they are, we will discuss them later on in the article.

How to choose the best Cot Bed Mattress?


Cots are often smaller than cots beds. Even though there’s a lot more variation in sizes when we talk about cot beds, they are generally quite similar.

Usually, that’s around 145cm long, 100cm tall and 75cm deep. Most options will have side rails between 84-87cm high in the highest position. Sometimes that can be a challenge for a shorter person to reach over.

That’s why you should consider a product with a drop side that will reduce this height and make it easier for you to reach your child. Lastly, don’t forget to measure the space you have in your bedroom or the nursery you will be using.

Wood or Not?

The material used for the bed will showcase its durability and quality. Some choices are better than others, but people typically decide between wood or MDF (engineered wood product).

Of course, the cost and quality will depend on the type of wood. When you’re making a decision check on the label whether the mentioned material is used throughout or is only a finish on top.  

Teething Rail

Chewing the edge of a cot is a habit that many babies have. That can be dangerous for a baby or a toddler since it can cost damage.

However, you can prevent that by choosing an option with a teething rail. The protective covering on the side edges will help protect the cot and most importantly, your kid.


If you’re planning on continually moving your cot bed from one room to another, you might want to consider casters or mounted wheels. They can come in handy, plus with them, it’s going to be much easier for you to clean underneath the bed so that no specks of dust stay around your child.
