This "thing"

I have been searching for this "thing" for months. We have two blankets on our couch for those who want to take a nap, but they always seem to end up on the floor. When I saw a picture of this "thing" in an English home magazine, I knew this was what I needed. I tried to find it on Ebay, but I didn't know how it was called. Until last Saturday...we went shopping for something completely else and what did I see in the sales corner? Yes! I still don't know the name (any suggestions?), but I am really happy I found it.
