When it comes to choosing the best mattress protector for bedwetting then advanced waterproofing is the key. Be sure to look for protectors that are labeled as “waterproof” or “water-resistant”.

These will help to block the moisture from ever reaching the mattress. Some protectors offer layers which are both waterproof and absorbent, these are a great choice as the absorbent layer will wick moisture away from the surface, which is particularly good for children who may not wake up if they have an accident, and then the waterproof layer protects the mattress.

A good-quality mattress protector can help trap allergens from dust mites, pet dander, and pollen, leaving you sleeping much better and waking feeling fresh. It’s important to look at the pore size of your mattress protector.

Anything under 10 microns should mean that even the smallest dust particles are blocked. Always look for options such as microfiber, tightly woven cotton, or specific allergen-proof materials.

Consider going for materials such as cotton terrycloth, which absorbs moisture whilst allowing air to circulate, or breathable PU, which, again, is waterproof but will breathe. It’s also worth looking for mildew-resistant mattress protectors or ones with anti-microbial properties that will help suppress mold growth.

What happens if you don’t use a mattress protector?

It may be tempting to skip buying a mattress protector but they are really important to maintaining the good health of your mattress. For a start, when you don’t have a mattress protector on your bed you’re risking damaging your mattress from stains and spills.

Of course, accidents happen all the time, whether it’s accidentally spilling your morning cup of coffee or a bedwetting incident, you can’t guarantee that your mattress will never face a moisture emergency. But at least when you have a mattress protector, you are protected against these spills.

Another thing is that we all sweat at night, our body oils leak and go on to the mattress which in turn causes stains. And no one wants a mattress that is full of stains. Not only that but sweat and body oils can cause a damp environment, which is ideal for mold growth which has negative health ramifications as well as causing nasty odors.

Then there’s the exposure to dust mites and allergens. Over time our dead skin cells, sweat and other dust and debris build up on the mattress and create a breeding ground for dust mites. This then can cause allergic reactions from coughing and sneezing to itchy skin.

Everyday wear and tear can take its toll on your mattress. If you want it to stay fresh and enjoy a long life, then a mattress protector can provide the barrier that you need. Skipping a mattress protector may save you a couple of dollars, but buying one is the perfect investment as you’ll enjoy a cleaner, healthier sleep space.
