Kim Kardashian Sells Mansion -- Sacrifices Her Couch ... for $5 Million Mansion Sale

If you're a couch in Kim Kardashian's house, don't get too attached -- TMZ has learned when she unloaded her Beverly Hills mansion recently ... all the primo furniture was included in the price.

Sources tell us ... Kim quietly sold her 4,000-square-foot pad -- the one she once shared with Kris Humphries for a hot minute -- for just under $5 million. She bought it in 2010 for $4.8 million.

We're told Kim wanted a quickie sale -- she has that other mansion to nest in with Kanye West -- so when the buyer asked to have all the high-end furniture included ... KK gave it up without a fight.

The lucky buyer scored everything from couches, to coffee tables, to custom made pieces like Kim's favorite glam station vanity dresser (which we're told was hard for her to part with) ... all totaled worth hundreds of thousands of dollars.
