My room in my old apartment was a mattress on the ground for 3 solid weeks before I bothered to get a bed frame (old bedframe kind of broke in an irreparable way during the move)
There was something deeply visually funny to me about a completely furnished room with a wardrobe, lamp, turntable with speakers, vinyl collection, decor, etc completely in place, but then the bed is just a mattress w/ no sheets and a sleeping bag on top in lieu of a blanket w/ a tiny square cushion for a pillow, and also the mattress is in the middle of the room not touching any walls like Charlie Bucket's grandparents. So I kept it that way for the housewarming and for a week after that.
They got Lionel Richie for the CCTV Spring Festival Gala???
