What may cause mold in your mattress

Why is mold growing inside your mattress? Here are the most common reasons:

  1. Too high humidity levels. Moisture is what mold needs to grow. Air should circulate all the time, your bedroom should be ventilated regularly, even if it is winter.
  2. Mold on your furniture. Keep in mind that mold spreads really, really fast. If you already have mold on your walls and/or furniture, you will inevitably find it on your mattress sooner or later. That is why placing your mattress in a room with mold doesn’t make any sense - you should get rid of mold on your walls and furniture first.
  3. Spills. This is the most common reason why mold grows on a mattress. The truth is it is just too pleasant to drink beer or soda or any other drink in your bed, and the liquid is spilled very often. If you have no waterproof protector, your mattress is likely to become wet and as we know, moisture is a perfect growth medium, and that is why you need to act immediately if something is spilled on a mattress.
  4. Low-quality, unprofessional mattress cleaning. You just can’t clean the mattress without using the liquid, the solution to kill bacteria (which can be also used to kill mold, too), to be exact. The solution itself works great, but the problem starts if you or a specialist fail to dry the mattress properly. Moisture in the layers turns into the growth medium for mold.

How to prevent mold growth in your mattress

Cleaning your mattress from mold is not the easiest task to do. This is a time-consuming process and you never know if you really get rid of all the organisms inside your bed. That is why you should do everything you can to prevent its growth. The good news is it is pretty easy. Just follow these tips:

  • A dehumidifier is what you need. As we have noted above, mold doesn’t grow in a dry, ventilated room. However, in some cases, it is pretty hard to provide proper air circulation. That is why we recommend using a dehumidifier.
  • A purifier is another great solution. This is another pretty good option for those who want to prevent mold. It is not super cheap, but a hundred bucks or even a few hundreds are still cheaper than most quality mattresses on the market.
  • Open the windows, let the air and sun do all the job for you. If it is too cold or windy for you, do it when you leave the room for at least a few hours.
  • Get a good bed base. Flip a mattress if it is flippable or at least make sure that air circulates properly on the bottom, as well as on the top side of your mattress. Slatted frames and foundations are the best when it comes to ventilation.


Don’t underestimate the dangers of mold - it has tons of negative effects even if it is in your bathroom, not to mention the mattress on which you sleep every single day. Follow the tips above to prevent the problem or get rid of it if it is already here.
