after 3 weeks full of spots Kivig Tullinge

I am so annoyed....we bought a new sofa at the end of last month. Kivik with the Tullinge cover in gray-brown. It looks great, is really comfortable but even though we explicitly do not eat or drink on the sofa (which the sons find very unfortunate), the sofa is mysteriously covered in stains. What on earth is that supposed to be??? I am totally disappointed, and I don’t think it’s because of our cats. My husband already thinks I’m crazy because I’m so picky since I don’t want the stains...now I’ve also put blankets on it :oops: Do you have any idea? Man!!

This sounds very ominous. Can you please take a photo? Does it look like there is something on the fibers or...?

Well. Spots usually don't appear out of nowhere.
