The mattress is the heart of a good bed – and at the same time is exposed to quite a lot every day: sweat, skin cells and moisture. A mattress protector reliably protects it and also ensures greater hygiene in bed. We show you the benefits of a mattress protector and the different types available.
What is a mattress protector?
A mattress protector is an additional layer between the mattress and the fitted sheet. Depending on the design, it may be referred to as a mattress pad, mattress cover, fitted mattress pad or encasing. They all have one thing in common: they protect the mattress and improve hygiene – without compromising comfort.

Benefits at a glance
1. Greater hygiene
A person loses up to half a litre of fluid and numerous skin cells every night. A mattress protector catches most of this and, unlike the mattress itself, can be easily cleaned in the washing machine. This keeps the sleeping environment fresh and clean.
2. Protection against moisture and stains
Waterproof pads in particular prevent moisture from penetrating the mattress. This is ideal for children's beds, incontinence or simply as a precaution against stains – and protects against mould and unpleasant odours.
3. Fewer mites – good for allergy sufferers
Because a mattress protector can be washed at high temperatures, it deprives dust mites of their means of survival. Combined with washable bedding, it is an important component of allergy-friendly sleep.
4. Longer mattress lifespan
Sweat and moisture take their toll on every mattress over time. A mattress protector keeps it fresh for longer and can significantly extend the lifespan of your investment.
5. More comfort
Many pads, such as those made of soft molton, also provide a pleasant, soft feel and even out minor unevenness.

What types of mattress protectors are there?
-
Molton pad: soft, breathable cotton protection for everyday use.
