I guess I'm more like you (furniture/spot) and yet I understand the feeling of those who view a space differently. As mono mentioned, there is an 'energy' that gets released into an area that can make it special. For me/us we feel adding to that energy is actually erotic. It doesn't detract from it. But that's us.
All else fails - buy an air bed - put it where you want ! They have advantages as you can get wilder and more creative (especially with multiple partners) and not worry about someone getting bounced off on the floor from 2 feet up !
This was an interesting dynamic in our full motion waterbed. The 'wave' effect has caught more than one person unawares. Good for laughs but kind of breaks the moment when someone hits the floor.
