What Makes a Quality Cot Bed Mattress?

Despite the obvious qualities such as thickness, softness, and pleasant tactile feedback, there are more things to look for under the surface layer when searching for the best cot bed mattress. You need to choose models that are both comfortable yet durable, without necessarily burning a hole in your pocket. So let’s see what makes the best cot mattress in the UK.

The material

The best cot bed mattress would feature non-toxic materials and a soft hypoallergenic surface. It won’t be rare that the material composition is made of polyester, with the possible addition of polypropylene as well. Eco-friendly fibre materials are a plus, though not necessarily detrimental in regards to quality.

Furthermore, since most cot mattresses these days are fire repellent, it is essential to ask about the composition of the material, especially with regards to toxic elements such as phosphorus, arsenic, and antimony (most commonly used as fire retardants). A good quality cot mattress would not include these materials.

Compliant to the latest British standards

It is important that both the material and the manufacturing process are in compliance with the latest and highest standards of quality required in the UK. Therefore, see that the model has the BS1877-10:2011+A1:2012 and BS7177:2008+A1:2011 compliance at least.

Structural integrity

While you can genuinely argue between foam mattresses and pocket sprung cot bed mattresses, the case for picking a winner is somewhat nuanced.

Foam mattresses would adapt better to the body, but they are more absorbent when it comes to moisture. If your home is humid, and you have general problems with mould, the foam mattress would require an occasional “breathing” outside.

On the other hand, a pocket sprung cot bed mattress would be more breathable, preventing odour and moisture from absorbing. The con, however, is that a pocket sprung model might provide less comfort since it sinks deeper as you apply weight. Having in mind that kids weight less when compared to an adult, this is not an issue. A combination, therefore, between the two – both springs and foam – is generally the best option.

High quality quilted cover

Kids being kids, there will be an occasional bedwetting incident no matter what. It helps, therefore, to have a water-resistant cover that is easy to unzip and put into the washer. Look for materials that can endure washing at 40 degrees at least. A high-quality quilted cover would come included in the price, protecting the cot mattress for years to come. Some are double-sided, providing both a winter, as well as summer side to sleep on.

A softcover can add a layer of comfort, while at the same time protecting the surface of the mattress. Look for hypoallergenic materials, specified under description or features.

Positive feedback

While it is easy to follow the instructions from above and analyze the best cot mattress through and through, the fact remains that much of the material is hidden underneath the surface. Nobody can predict whether a cot mattress is high-quality enough to resist the test of time, without losing shape and comfort. The safest bet, therefore, would be to buy popular listings, with a fair number of positive reviews.


If you are buying for a specific bed, always have a look at the inside dimensions for your bed, and make sure to specify the size of the model you are ordering. While it is convenient to buy larger models, and hence save on extra expenses after a couple of years, it is less so when you find out that you have to buy a new cot bed as well.

Most of the cot mattresses should have the measurements specified, and you will find out that many fit easily into a travel cot. Nevertheless, make sure to double-check the cot bed mattress size. The most popular sizes are the cot mattress 120 x 60 cm, cot bed mattress 70 x 140, and the cot mattress 140 x 70 cm. You will find several such in the compilation below. Also, note that the maximum allowed height for cot bed mattresses is only 10 cm. With the cot mattress guide behind, let’s focus on the best cot bed mattress models in the UK.
