Caring for top mattresses
Familon top mattress is made from safe and materials. Regular vacuum cleaning will keep it clean and fresh. Don't beat your top mattress with a carpet beater. Regularly flipping and rotating it from end to end will extend its life.
You can get rid of the "new mattress smell" by pressing the mattress while vacuuming it. The smell is completely harmless and will go away by itself over time.
Note that the memory foam used in some mattresses reacts to temperature and hardens if aired outside in sub-zero temperatures. This is perfectly normal, and once back indoors it will straighten out and soften at room temperature. The mattress will keep its shape better if you only air the protective cover.
Washing the removable cover: Close the zip and remove the foam before washing. Once washed, straighten and reshape the cover, then leave it to dry in a well-ventilated area. If you wash the whole cover, keep the zip closed. Replace your top mattress every four years or so.
