The B-Sensible 2-in-1 Fitted Sheet Protector won Bronze for Best Bedding Product at the 2021 Mother&Baby Awards.
B-Sensible bedding offers unique protection for mattresses as the only 2-in-1 waterproof fitted sheets that are made from 100 per cent natural, sustainable, and eco-friendly fibre Tencel, which originates from the Eucalyptus tree.
As well as being waterproof, B-Sensible sheets are breathable, softer than cotton, crinkle-free, temperature regulating, naturally antibacterial, and can be machine-washed and tumble-dried. They're infused with the natural element zinc oxide which not only has antibacterial properties but also has positive effects on the human body, in particular on skin.
Our mum tester Diana said: "I can put my baby to sleep knowing that I will not wake up to a wet mattress and that I will be able to wash her bedding and tumble dry it and have it ready for her nap as it can be tumble dried, which for me it is a must. I have washed the sheet protector a lot and it has kept the same quality as the first day, it even got softer with washes which I was very pleased with."

The Little Green Sheep Waterproof Mattress Protector won Gold for Best Sleep Product at the 2016 Mother&Baby Awards.
Machine washable and tumble dry safe, this flat and super soft cot mattress protector from The Little Green Sheep is made from a breathable and extra absorbent luxury cotton, creating a dry and safe sleep environment for your baby. It's super soft and comfortable but not fitted - it simply acts as a breathable, protective layer on top of your baby's mattress.
Our mum tester Becky said: "It is great because it prolongs the lifespan of a mattress especially through the toddler/preschool years. In the event of night time leakages it is easy to take off the bed and wash in the machine. The single size is expensive but great value for money considering the level of comfort and the amount of use you would get out of it."

Should mattress protectors be waterproof?
Not all mattress protectors are waterproof, but you should make sure that your little one's is.
The Lullaby Trust recommends a waterproof cover, or in other words a mattress protector, as it will keep your baby's mattress clean and dry, and prevent bacteria from collecting in the foam. By preventing the build-up of bacteria inside the mattress, there is a reduced risk of infection which may have otherwise increased the risk of SIDS.
To make sure the mattress cover is suitable for your baby, you should opt for an organic waterproof mattress protector or one made of natural fibres such as cotton. This is a soft, breathable choice that'll be best for your baby's comfort, and can easily be removed and washed too.
Happy baby and happy mum!
What is the best breathable waterproof mattress cover?
While all our shortlisted waterproof mattress covers would make a great fit for your baby's bed or cot, we'd recommend the B-Sensible 2-in-1 Fitted Sheet. Not only is it a Mother&Baby Award winner, but it also provides soft, natural, protection, is extra kind to your baby's skin, and is super easy to clean. Plus it's the mattress cover with the biggest range of sizes and colours so you're sure to find the ideal fit and style to suit your baby from Moses basket to their big bed.
Do waterproof mattress covers make you sweat?
A cheap, plastic mattress cover will, which is why it's important to pick one like those on our shortlist that are designed to be sweat-wicking, breathable, and soft so as to remove the possibility of your little one overheating.
How often should you wash your mattress cover?
Dreams, the Sleep Specialists, suggest that you should change your mattress cover every two months, but for your little one, we’d recommend washing it every one to two weeks. Pop it in the machine on a cold or lukewarm gentle wash using a mild detergent and let it dry naturally.
