As there is no longer a Micasa in Chur, I would like to know the following links: are these articles waterproof if liquids such as tea or coffee are spilled on them and can these articles be sent to any branch for inspection? Thank you. https://www.micasa.ch/de/p/404428812000/komfortschaum https://www.micasa.ch/de/p/407713512010/visco
