Is Matt's cover washable?

Of course. We recommend washing the cover approximately once a year. The top layer of the cover with tencel is washable at 60 degrees Celsius. This keeps Matt hygienic and gives dust mites no chance. The blue part with anti-slip is up to 40 degrees Celsius washable. The parts of the cover should not be put in the dryer. This will cause the cover to shrink. Read the washing label carefully before washing.
