Silverfish
Thanks for all the replies!
I just cleaned the room in depth, specially the couch, and washed the covers. I only saw that one, I suspect it came with the covers.
Check your books and papers. That's where you really need them to stay away.
I thought it was normal to see silverfish every once in a while - but that if you see a lot of them it could be a problem.
It's pretty normal to see them in a bathroom or kitchen, as they like damp areas; I have no clue about finding them in couches, tho.
100% a Silverfish OP. That's not good news.
Silverfish are harmless. And no issue if there is just a few of them.
Silverfish are harmless
They are attracted to glue, book bindings, paper, sugar and textiles. Silverfish can destroy silks, cotton and other fabrics and may feast upon leather in the event of a famine. Silverfish inhabit dark, damp areas such as closets, attics and basements and will feed upon paper and linen stores in these locations
Do you keep your sofa in a dark damp location? If not then your safe.
