Cot Mattresses

What is the size of a cot mattress?

Cot mattress sizes are 120cm long and 60cm wide, so just a little smaller than toddler size. They're usually 10cm deep which is the optimum depth to provide the right support for babies.

Why choose a cot mattress?

Expertly designed for the challenge, our cot mattresses offer helpful features that will ease those long nights with a newborn.

Water repellent covers

At such a young age, accidents are likely to happen. That's why it's important to have water-repellent covers on a baby's mattress. This means you can easily wipe them clean, without the need for disturbing your child's sleep. Long gone are the days of flipping over the mattress and then tackling the issue come morning. Cot mattresses that are water repellent provide you with a quick solution to any night-time accidents, meaning you can get back to bed quickly too!

Hypoallergenic qualities

Choosing a mattress for a cot bed that has hypoallergenic qualities helps reduce the risk of allergic reactions and respiratory issues.

Removable covers

As well as water-repellent covers, you'll want an easily removable cover too. Usually machine washable at 60 degrees, these can make your life much less stressful. What's more, these cot mattresses can often be used without the cover. This allows you to whip off the cover, throw it in the washing basket, and tackle it at a reasonable time.

Breathable materials

It's not until 9-12 months that we're fully able to regulate our temperature, so it's extra important that your little one has a breathable, cooling mattress that can keep them comfortable while they slumber.

How comfy should a cot mattress be?

As a child's bones are still developing, they need a mattress which will keep them aligned, ensuring they grow properly . For this reason, cot mattresses are usually only available in medium, medium-firm, or firm comfort levels.

What types of cot mattresses are available?

Because of all the health requirements, cot mattresses don't come in as wide a variety as those for adults. However, that doesn't mean you don't have plenty of choice.

PVC-free foam cot mattresses

A breathable foam filling is a soft and reliable option for the nursery. These mattresses tend to be cheaper, so if you're furnishing on a budget then you can rest assured that you're not compromising quality.

Remember all of our beds and mattresses come with free UK delivery and when spending over £500, you can explore our finance options to help spread the costs with interest-free payments.

Pocket spring cot mattresses

Pocket spring cot mattresses are one of the most popular types of cot mattress. Each mattress spring is placed in an independent pocket, helping the mattress respond accurately to your child’s sleeping position and night-time movement.
