Anything that lets you sit (chair, couch, etc.) is called asstray after you get up from it. Because the seat becomes hot after you sit on it for a long period. It is a blend of ass and ashtray (ashtray is hot as people drop the ashes of cigarettes into an ashtray).
(In a bus...)
Young man: Come ma'am. You can have my seat.
Old lady: No, thanks. I do not want my bum to get roasted by the asstray.
