I was having exactly that thought on a ratty mock-leather couch in Islington.
Ratty clothes and objects are torn or in bad condition, especially because they are old. my ratty old flannel pyjamas
showing signs of wear and tear; "a ratty old overcoat"; "shabby furniture"; "an old house with dirty windows and tatty curtains"
If someone is ratty, they get angry and irritated easily. I had spent too many hours there and was beginning to get a bit ratty and fed up. = irritable
{s} infested with rats, teeming with rats; (Slang) unfair; (Slang) crummy, in bad condition (example: "He has a ratty car, looks like a wreck")
