We didn't have a bed frame for years, and it drove my wife crazy. I'm weird with furniture, where I won't buy something, until I find the exact thing I want. Took a few years, then I finally found a frame I liked at a price I was willing to pay. Haven't regretted it. It makes our bedroom look nice. 

 but why drive crazy? They just think it looks bad?

I'm beginning to think there is some kind of instinctual thing going on here  

 I'm not sure, honestly... They may just like the idea of being fucked on a pedestal, instead of the floor 😂
