10 Best Cot Mattresses in UK 2024

Newborn babies are fragile and need to be handled with delicate care. As parents, it is only natural that you wish to give your little bundle of joy the best in the world and keep them safe. The wrong mattress will not just ruin their sleep (which they spend the vast majority of their time doing) but could also pose serious safety issues. It therefore follows that choosing the best baby cot mattress in the market is one of the most important tasks every parent faces. Fret not, we have compiled a comprehensive guide so you know what to look for and included our recommendations so that you can focus on caring for your baby.

Key Factors to Consider When Buying a Baby Cot

Before diving into our list of 10 Best Cot Mattresses in the UK for 2024, here are some key factors to consider before making your purchase.


Babies require more support at this stage than they would at any other. It is critical that their mattress provides sufficient support in order to prevent Sudden Infant Death Syndrome (SIDs), which is a pertinent problem. Soft mattresses are therefore a huge no-no. Ensure the cot mattress is firm and does not sag or have any indentations. A rule of thumb is that the mattress should not be thinner than 8 cm. 


Your infant’s safety is of utmost importance. Therefore, make sure to choose a mattress that follows the British Safety Standards (BS 1877-10:1997, and ideally BS EN 16890:2017 +A1:2021).


The size of the mattress should fit right in with your cot. It is preferable to choose a double-sided mattress for long-term use. The typical cot bed measures around 140 x 70 cm, but we recommend taking measurements yourself to be safe.

Breathable Structure

The temperature of your little one is vital for a comfortable sleep. Ensure the cot mattress you choose is made with breathable fabric to maintain an optimised temperature for your little one.


It is best if the mattress comes with a waterproof cover for a variety of reasons. For starters, it keeps the mattress clean and dry, which are conducive qualities for the baby’s sleep. Also, there are high chances that your little one might wet the bed, or you may spill something on it while feeding them. Therefore, choose a cot mattress with a removable cover for your cleaning convenience.
