What Is the Best Cot Mattress for Your Baby?


What cot mattress is best for my baby? How thick should the cot mattress be? What special features does it need? How should it fit?

There is no doubt that buying a mattress for a baby’s cot can seem a bit overwhelming. Normally, when buying a mattress, the biggest concerns are comfort and support. However, with a baby’s cot mattress other factors such as safety, absorbency, thickness and hygiene come strongly into focus, making choosing the right one feel like an impossible task.

The importance of finding the right mattress for your baby is crucial for both their sleep and for yours. That’s why, to make the process easier, our experts here at CuddleCo have broken down some of the key elements you should look for when deciding which cot mattress is best for your baby. 

What Is the Best Cot Mattress for Your Baby?

Whether buying a cot mattress or a cot bed mattress, you want a firm and flat mattress protected by a waterproof cover to help keep the mattress clean and dry. You can assess for the firmness and flatness of the mattress by pressing your hand firmly into the centre and edges. There should be some resistance and it should bounce back immediately. Make sure it's in good condition and fits the cot or cot bed you're using it with.  

At CuddleCo our range of cot mattresses have pulled together all the expertise and knowledge of the industry to ensure they provide the level of technical support your baby needs to sleep soundly. We understand the importance of sleep for a baby’s development, which is why our collection of cot mattresses have been hand-picked for their ability to ensure that your little one gets the crucial restorative rest they need for their development. 

What Are the Different Types of Cot Mattresses?

There are many different types of cot mattresses available in the market. However, when it comes to your tot, we want to make sure they are getting the very best in terms of quality, support and safety. 

  • Foam Cot Mattresses generally speaking, foam cot mattresses are the least expensive type of cot mattress. They are very simple, crafted from a piece of high-density foam. Some will come with two sides: a cotton side and a wipe-clean side. Most are easy to clean and can provide good support for your baby.
  • Spring or Pocket Spring Cot Mattresses — a spring mattress is made of springs secured into a rigid frame. These are then surrounded by layers of foam and fabric. Pocket spring mattresses, on the other hand, are made of coiled springs, each sewn into their own individual pocket.  Unlike a regular spring mattress, each spring in a pocket spring mattress can move independently of the others, so the mattress is deemed to be more comfortable and give better support. These springs are, like regular spring mattresses, covered by layers of foam and fabric. 
  • Hypoallergenic Cot Mattresses these mattresses have natural or organic anti-allergy technology, designed to kill any dust mites that may cause allergies. They are easy to keep clean and give an additional element of protection for your baby against harmful allergens.

  • How Should a Cot Mattress Fit?

    Be aware that not all cot mattresses come in the same standard size, but your cot or cot bed should specify which size cot mattress it requires. 


    You need to make sure your cot mattress fits your cot or cot bed frame snugly. All mattresses should comply with the BSEN 16890 Safety Standards . You should always check that the mattress you are buying meets the latest safety standards to ensure that it is regulated to the correct firmness, gap dimensions and toxicity. This will give you peace of mind when it comes to the most pertinent safety matters.

    Other Features of Cot Mattresses to Look Out For

    Did you know there are millions of house dust mite allergens in every bed, and that a quarter of the population suffers from an allergic reaction to them? 

    You can now buy cot mattresses, like the ones in the Mother&Baby Gold Collection at CuddleCo, which are treated with a new technology called Purotex. This technology is built with 100% natural probiotics — like those you find in yoghurt — to permanently destroy 93.7% of dust mites, 92.8% of cat allergens, and 66.7% of dog allergens, promoting a cleaner and healthier sleep environment for your baby.

    Look out for mattresses that are also covered in Tencel, which is made from the pulp of trees grown on special farms and is made using recyclable, earth-friendly chemicals — making it an environmentally-friendly, sustainable choice.

    One of the cot mattresses we stock at CuddleCo in the Mother&Baby Gold Collection range is even certified by the Global Organic Textile Standard (GOTS) as it is 100% chemical-free and organic. Handmade in the UK, the mattress is treated organically from the harvesting of raw materials through to its manufacture and packaging, crafted with a luxury quilted herringbone cover to guarantee a comfortable sleep for your baby. It provides your little one with two types of support; as a baby, it promises to provide your child with a firm feel, as recommended by sleep experts. As your baby grows into a toddler, the mattress provides a softer, medium level of support for extra comfort.
