Typically this type of black mould is mildew; however, if this mould is left untreated, it can progress and cover the entire mattress. This can damage the bed while also releasing spores which could have an impact on your physical health.

Mold on Memory Foam Mattresses


Memory foam mattresses are made using many different foams. The problem with many foams is that they absorb moisture and holds it, meaning that mattresses can collect the sweat and liquid from your body over time. This moisture can get to the bottom of the bed where it can cause mould growth.

Some people believe memory foam mattresses are arguably more susceptible to mould than spring mattresses because memory foam lays flat against the ground and holds more moisture. These two factors mean that there is less airflow and more moisture, both of which encourage fungus growth.

If there are visible signs of mould on your bed, you will need to act quickly and take steps to mitigate the problem as soon as possible. It will be hard work but must be done to prevent future recurrence

Step-by-Step Guide for Removing Mold From Your Mattress


  1. Start by vacuuming all sides of the mattress, including the top, bottom and sides. As soon as this is done, empty your vacuum thoroughly to prevent the spreading of mould spores.
  2. Next, take equal amounts of rubbing alcohol and warm water in a container. Dip and wring out the cloth, and use this wet cloth to scrub the mattress’s mouldy area. You can also use a spray bottle to apply the solution. Using the cloth rub, in a circular motion on the mould spot, and go well beyond the area of visible mould.
  3. Then, rinse this part of the mattress with a different cloth lightly moistened with warm water. It would help if you took care not to have the cloth too wet which would add too much extra moisture to your mattress. Excess moisture could result in more mould growth.
  4. When that is complete, you can choose to very lightly spray on a disinfectant suitable for upholstery and foam usage over the surface of the mattress, after allowing the bed to dry by keeping your windows open or using a dehumidifier.
  5. If it is possible, you can try and take into direct sunshine. This will help dry out your mattress while inhibiting more mould from growing since the UV rays from sunlight prevent mould growth.


Mould Under Mattress

Most commonly grows on the bottom of your bed, it is still possible in other places. The primary reason why most people find under their bed is that there is practically no light exposure and minimal air circulation. The top and sides of your bed are allowed to breathe and get exposed to light(sunlight and artificial light) which typically prevents mould growth and receiving air every time; you lift your bedsheets.

Mould on the other side, you should try to make a conscious effort to increase the airflow under the mattress and bed. You can do this by opening your room’s windows periodically and using a dehumidifier in your bedroom.

Furthermore, you can choose a bed with slots rather than a boxspring that prevents air from reaching the mattress’s bottom. Make sure there is a gap between the slats to allow plenty of airflow. It’s also a good idea to make sure there is a sizable gap between your mattress the floor.

It’s also good to regularly lift your mattress to check for early signs of mould and see if you can detect any smells.

You can also leave your mattress leaning against the wall until the bed dries, reducing the risk of fungus developing by keeping good airflow on the underside of the mattress. Air needs to circulate properly on both sides of the bed to help prevent mould, – not just one side


Mould Mattress Protector

If your mattress already developed mould, a mattress protector will not help and could make the problem much worse. A mattress protector will trap moisture and create an environment in which mould can grow. Additionally, if you cover your mattress to prevent mould growth, if there is moisture in your bed before applying the protector, this could trap moisture and cause mould. Your best option to prevent mould growth is to keep your mattress as dry as possible by routinely airing out your bed and following the next section’s steps.


Prevent Mould on Mattress

If conditions are conducive to mould growth, it can be challenging to stop mould from taking hold of your mattress and other parts of your home.

The best way to prevent mould growth is to use an air purifier in your bedroom as air purifiers help circulate and filter the air. When you use the appropriate type, an air purifier can remove mould spores from the air. Although removing spores will not kill mould on surfaces, it will help decrease the amount of airborne mould in your bedroom. This will help prevent future mould growth on your mattress and even your bedroom. It can also be an excellent idea to let the air circulate, especially before being away.



A long term solution might be to purchase a latex mattress and slatted bed base. Latex foam mattresses are naturally mould and bacteria resistant as well as being very comfortable. They are also frequently recommended by chiropractors and physiotherapists. A natural latex mattress is a way you can guarantee you won’t have to deal with mould on your bed again.
