Feel & support

Your baby needs a firm feel. This means that you should provide it with a sufficiently solid surface, and it should not sink into the mattress. Its primary function is to support the whole body. Since the baby sleeps a lot during the first two years of life, the choice of mattress is very important. A soft model is a comfortable option, but it can also lead to overheating and increase the risk of suffocation. So read reviews and find out which mattress has best balance between softness and support.

Machine washable & removable cover

During the first few lives of a child, accidents are almost inevitable. That is why materials that are easy to maintain or machine washable are used. Cot bed mattress can be used for several years which means that over time more and more effusions, stains and even faecal bacteria are deposited. To provide your child with a hygienic sleeping area, you will need to clean it regularly if you do not have a removable cover. Get it on time so that your mattress lasts as long as possible and so that dirt does not accumulate. In some cases, you will get removable cover with mattress and in some cases you don’t.

Hypoallergenic properties

Hypoallergenic mattress prevents the penetration of mites, mould and bacteria. This means that it significantly reduces the chances of developing allergies, which makes it an ideal choice for children, because a clean bed is very important for your child's health. In this case, a springless, all-foam mattress is best, because the foam has a very resistant structure. Of course, any mattress can offer great protection if a suitable cover is placed over it. You must also pay attention to hypoallergenic properties because baby can develop asthma if you fail to buy hypoallergenic mattress and cover.


A child's bed usually gets dirty often and that is why it is always good to think about investing in mattress protection. In this way, all dirt will be removed very quickly and thoroughly, and the mattress will not have to be cleaned. For example, a foam mattress without a waterproof cover can be seen as a large sponge that will only absorb all the liquid and eventually become unusable. It is enough to get the bed dirty like this once for bacteria, mould and fungus to start appearing.
