With all these options available, this can be a hard task for expecting parents. For this reason, we decided to do all the research for you so you can focus on other stuff.

With more makers developing cot mattresses these days, there are plenty of options available so you should set your budget and then choose the cot mattress that suits your baby’s needs. Make sure that you put safety first and if you want more information on that you should read this great piece by the Lullaby Trust. With all that n mind, we have gathered for you 6 options that we believe are great for your baby.

What size cot mattress do I need?

Most makers offer 2 sizes with standard cot mattresses measuring 120 x 60 cm and cot bed mattresses measuring 140 x 70 cm. That means that if you have already purchased a cot bed you will probably need the bigger option. In any case, make sure to check the dimensions needed before you complete your purchase.

What types of cot mattresses exist?

Just like adult mattresses, there are plenty of options for you to choose from. Below, we will talk about the available options.


Mattress makers prefer to use foam as it’s affordable and it’s easy to use. Having said that, this doesn’t mean that foam cot mattresses lack quality. On the contrary, a firm foam mattress can be very supportive and it’s safe for your baby.

Pocket spring

This type of spring is known to be very supportive and it’s usually combined with other foam layers. In addition, mattresses with pocket springs are more durable but they tend to cost more.


This is the standard open coil type of mattress that is more affordable and if correctly done, they can be very supportive. The downside is the lack of durability.


Many cot mattresses use natural materials like latex and wool. Natural latex has pressure-relieving properties and it’s very supportive but it’s not the cheapest material out there.

In this guide, you can find every type of mattress so you should choose according to your needs.

Editor’s Pick – Safe Nights Luxury Cot Mattress

The second pick on this list is the Panda Cot mattress. If you read this blog, you know that Panda is one of our favourite brands and we are really happy that they decided to create a baby mattress. Just like the rest of their products, they use a bamboo cover that has a number of properties. It’s breathable but at the same time, it’s naturally hypoallergenic and anti-bacterial. In addition, it can regulate your baby’s temperature and it’s an eco-friendly material. All these reasons make bamboo an excellent material for a cot mattress.
