A tumblr called just another ikea catalog [VERY NSFW] consists of clips from hardcore pornography in which Ikea furniture appears, converted to animated GIFs with catalog-style product names and pricing superimposed as appropriate.
An article in Neue Westfälische (machine translation to English) quotes a German trademark specialist who believes that Ikea may be able to have the site censored under a German legal doctrine that entitles companies to protect their "business honor" ("Geschäftsehre berufen"), which is not something I've heard of.
Meantime, just another ikea catalog [again, VERY NSFW] remains as a testament to the ubiquity of Ikea furniture, which has become a kind of modern default background in just about every interior, including porn sets. (via MeFi)
