What Is A Baby Cot Mattress?

A baby mattress is a sleeping surface that is made specifically for babies and infants that can integrate into their existing cots to provide much-needed comfort and support

When you purchase your cot, there may be a mattress included but don't feel forced to use it just because its included in the price. The most important thing is that when you buy the mattress that you're happy with it because your baby is going to spend most of the next few years lying on it.

Why Is A Good Quality Baby Mattress So Important?

On a serious note, despite a cot mattress providing a comfy sleep for your baby, more importantly, it adds extra safety and protection while they sleep through the night.

In America, the National Institute of Child Health & Human Development concluded in a report using a firmer baby mattress instead of a softer mattress is one of the major factors in helping to reduce SIDS or Sudden Infant Death Syndrome.

​This makes it even more important to use a mattress that has been specifically made for babies because adult mattresses are likely not firm enough for a baby to sleep on long term.

Types Of Baby Cot Mattress?

There are many different types of mattress that you can purchase; however, the most important thing to remember is that no matter which one you decide to buy, it needs to be firm.

To explain why; imagine if your baby turns over while sleeping if the mattress is soft your baby will find it challenging to move themselves because their face is more likely to sink into the surface of the mattress, so they need a more solid surface.

Foam Mattress

One of the most popular types of baby cot mattress is manufactured from polyurethane which is made into a foam material. It is generally a popular choice by parents due to being cheaper than models made with alternative materials.

This is no longer the soft, brittle foam that was available decades ago, huge advancements have been made to now manufacture top quality foam.

The most commonly have a PVC cover which makes it easy to wipe clean. The covers are removable and breathable and on occasion have additional ventilation holes to help keep your baby cool.

In general the denser the mattress, the better. Heavier mattresses are often denser. As previously stated, the more firm a cot mattress is, the better for the baby. The best manufacturers list the weight in the product information. An alternative way to test a mattresses firmness is by squeezing it with your hands. A top quality thick mattress will not allow you to push far into the surface.

Although generally speaking, a heavier mattress is better than a lightweight mattress; you have to take into account that you'll have to lift the mattress to change the sheets continually. A mattress that is too bulky and heavy can cause issues, so its best to make a compromise between ease of use and weight.


  • Easy to keep clean
  • Affordable and good value for money
  • Long lasting
  • Lightweight


  • PVC cover may be an issue for some parents.
  • The models that have ventilation holes can be a little harder to clean

Pocket Sprung Baby Cot Mattress

Pocket springs have been the natural development away from coil spring mattresses to provide an even more comfortable sleep. They are made up of individual springs that are sewn into small fabric pockets.

Each spring works independently to respond to the baby's movement and then adjusts its shape to contour and support your baby's body.

These mattresses are routinely more expensive than foam mattresses due to the more complex manufacturing process that it needs to produce.

While you do need to take note of the number coils that the mattress has before purchasing, you must understand that more coils don't necessarily mean the mattress is better than another will less coils.

The number of coils does slightly reflect the level of density of a mattress, though many other factors contribute to the quality of a mattress.

The recommended amount of coils should be around 130-150.. However, you can use your judgement here to make a decision based on your individual baby's needs.


  • High quality support
  • Extremely long lasting
  • Tend to be more heavier and denser
  • Lightweight


  • Can be more expensive than alternatives
  • The models that have ventilation holes can be a little harder to clean

​Coil Spring Baby Cot Mattress

Coil spring mattresses are the traditional type and structure that you're already used to. The mattress is made up of a coiled spring interior assisted by layers of foam and felt padding to provide comfort and support to the baby.

One side is normally covered in cotton or similar material, with the other side having a more durable PVC type material cover that is easy to wipe clean when dirty.

These mattresses tend to retain their shape well for many years, and built into its structure is a spring lattice. This ensures that a good level of airflow is maintained, so the baby's body temperature stays regulated throughout their sleep.


  • The majority of parents like the familiarity of a traditional spring mattress
  • Easy wipe clean surface to remove dirt and bacteria.
  • Long lasting


  • Generally more expensive than a foam mattress
  • The cotton side can be harder to keep clean, but does provide comfort.

Natural Fibre Baby Mattress

Natural fibre baby cot mattresses are made slightly differently to the traditional baby mattresses in the market. The core is made up of different materials such as coconut fibre combined with additional natural layers like lambswool, cashmere, latex or silk.

The coconut fibres are then reinforced with latex to provide protection, strength and support. The natural filling is so powerful because it helps more air to circulate through the mattress so not only does your baby get a comfortable sleep but their temperature is regulated to a higher quality.

Like most baby mattresses, they are manufactured to have an easy wipe cover to make removing bacteria and dirt easy.

This mattress is a suitable choice if you are worried about your baby sleeping on synthetic material or you are trying to avoid introducing additional synthetics and unnecessary chemicals into your home.


  • One of the most firmest mattresses, great for support.
  • This firmness means they retain their shape and last longer
  • Strong air circulation properties.


  • Less availability than other types of baby cot mattress
  • Noticeably more expensive than alternatives.

Hypoallergenic Baby Cot Mattress​

If your family currently suffers from allergens or asthma, then there's a chance that your baby will often suffer from the same issues. If this is a concern, then you may want to consider purchasing a hypoallergenic mattress for your baby.

Hypoallergenic baby mattresses are usually manufactured to have a quilted top layer which also it to be quickly and easily detached and washed. They can be washed at 60 degrees which is the optimal temperature to kill dust mites and bacteria that may cause or worsen allergies.


  • Great choice if you baby has allergens or asthma
  • Easy to maintain and keep clean


  • Often more expensive than other types of mattress
  • For the majority of babies, this is a luxury purchase.

The New Type of Hybrid Baby Cot Mattress

In recent times baby cot mattresses are often no longer separated by material, and now you will find that you can purchase mattresses made from a range of materials. For example, it may have a pocket spring foundation with a layer of foam.

This is even more effective because you get the benefits of two different types of structures and materials. So when you are purchasing a mattress be sure to check whether there is more than one key material.

Does My Baby Mattress Need To Be Brand New?

Preparing for a newborn can end up being reasonably costly once you account for all the items you need to purchase, and it is entirely reasonable for you to look for ways to save money that can be spent on other things.

We recommend that you always buy a brand new mattress for your baby, even if you have an old one that was used by your previous baby. Your new baby needs a fresh, clean start on a brand new supportive mattress.

The big issues with second-hand baby mattresses are that they can lose shape, so they are uncomfortable to sleep on. They can also be infested with hidden bacteria, germs or dust mites. Unfortunately, there is also strong evidence that implies that cot death cases can be linked to the use of secondhand mattresses.

Think about it this way, a previous baby has already slept on in for many of years, and part of that is spent peeing and pooing on the mattress. Regardless of how well it was maintained it's not a great idea to hand this down to another baby.

It has been stated by FSID's Sleep Simple Sleep Safe publication that: "In an ideal scenario you should purchase a new mattress for every new baby. If you are not able to do this, continue to use the one you have, as long as it was made with a completely waterproof cover and has no holes, tears or cracks. Clean and dry it thoroughly.” 

Buying Guide


There are several important steps you should take to ensure that your baby is as safe as possible before buying a new cot mattress for your baby.

  • Make sure that the mattress is firm and flat to provide support
  • Avoid Secondhand mattreses
  • Check product information to ensure that it meets the latest safety requirements
  • All baby mattresses should carry BSI number BS 1877-10:2011+A1:2012.
  • The mattress should fit in the cot snugly with no gaps around the edges.

Mattress Size

This may seem like common sense, but ensure that the mattress you purchase fits your cot. The majority of cots and mattresses come in standard sizes, but you should be sure to double check to ensure that it will fit.

A mattress that fits perfectly will be snug against all four sides of the cot with no breathing space or gaps present. If there's a gap, this presents a danger as your baby's limb could get caught.


Several manufacturers supply their mattresses with 10-20 year warranties which often play a significant factor in customers buying the product over an alternative.

You shouldn't let this alter your choice because the length of warranty doesn't always ensure quality. Plus realistically you'll only need your cot and mattress for a max of five years per child.


All baby cot mattresses are manufactured and covered with a durable outer layer of waterproof fabric. However, not all these covers are suitable for machine or hand washing. If your cover is not removable, then you must be sure to frequently wipe it clean with either a damp sponge or antibacterial wipe.

We recommend you either purchase a mattress with a removable cover or buy one separately to go with your mattress. This cover should be able to be washed at 60 degrees which is the optimal temperature to kill dust mites and germs.


You may be surprised to find out through this article that baby cot mattresses are reasonably affordable especially in comparison to how much use you get out of it and how many years it will last.

Usually, the thinner foam mattresses will be cheaper and affordable while the thicker, denser higher quality mattresses will cost a little more. You do get what you pay for.

Closing Remarks

It's a difficult decision to narrow it down to a single mattress. Although we recommend a spring, natural or hybrid system over a mattress that solely uses foam, people have been using foam mattresses for many years because not only do they provide quality orthopaedic support, but they also are extremely affordable.
