So different, yet so similar. In both manga, the guy has an unusual girlfriend (a fridge in one, and a chicken in the other). And most likely, in both, you will be left wondering what happened in the end.
(As Pasiphae no Utage is an anthology, this recommendation is for The Female Fridge No. 1 chapter only.)
Both are short stories with a strange, surreal premise - human turning into a furnitura or vice versa. The Female Fridge No. 1 is about a girl turned into a fridge, Dream Dust Box is about a girl who is half human, half trash can. Both involve sex.
