Most toppers are made of a foam . Your execution is probably a visco topper or a cold foam topper . These are made from a foam, the production process of which gives off an inherent odor .

Since the topper is shrink-wrapped for protection as soon as possible after production, the material hardly has time to air out. This means that the topper’s characteristic smell remains. If you open the packaging and unpack the topper, the smell will come out.

Fortunately, your health is not in danger. If you have decided on a high-quality topper , it is not contaminated with harmful substances. The smell even indicates that the foam is untreated. The “fresher” the foam, the more the topper will stink. This is another indication that it is a new product and that you have not received any old goods that have been in the warehouse for a long time.

If your new topper smells, this may be unpleasant, but it is not an indication that it is of poor quality. Air it out for about 24 to 48 hours and then use it without any problems.


Your topper is exposed to a lot of wear and tear during the night. It’s not just your body weight that weighs on the material. You also excrete sweat and flakes of skin , which affect the topper.

In this warm, humid environment, there are optimal growth conditions for mold and bacteria. It is therefore necessary to wash and air the topper regularly .

Spread out the topper and store it in a room that is well ventilated. Thanks to the intensive ventilation, the smell will dissipate faster , so that you can attach the topper to the mattress.

Open the zipper so that the draft of air reaches the foam core directly. Placed close to the window, the smell evaporates quickly, so that the waiting time goes by quickly.


If you notice the smell after using it for a while, it is probably time to wash the topper. The topper itself does not belong in the washing machine. The reference But you can usually wash at 40 ° C to 60 ° C in the machine.

If you are allergic , only choose covers that can be washed at at least 60 ° C. It is only at these hot temperatures that the mites die and are no longer a burden.

Wait for the cover to dry completely . The manufacturer may also allow use in the dryer , so that the waiting time is significantly shorter.

Stinks the core of the Toppers , then airing this out and make sure it is completely dry. Use a vacuum to treat the surface and wait for the odor to wipe off the material.

Decide on manufacturers who produce either in Germany or the EU. Then a stronger monitoring is guaranteed and the smell is only a natural side effect of the foam.


It is normal to a certain extent that you notice an odor after unpacking the topper . The foam has its own odor that has to dissipate after the production process. Air the topper out for around 2 days so that the foam no longer smells.

If you still clearly notice the smell after this time, an exchange may be necessary . Contact the manufacturer and they will likely offer a take-back.

Also wash the cover of the topper regularly and ventilate the foam core so that bacteria do not settle there. Then even after years of use the topper will not have an unpleasant odor and optimally support the comfort of your mattress.
