Are you allowed to sit on Holy books? I am guessing you are not allowed to because you need to show respect for Holy books but is it a halacha?
What about the same level? This is a less degree of disrespect are you still able/not able to sit down
What about put them on the floor? Putting things on the floor is a slight sign of disrespect but if you place them in a nice place that does not seem disrespectful is it allowed?
In the bedroom while you sleep there? Maybe it's disrespectful to sleep in the same room as Holy Books.
Details and sources as always.
