Neither, IMO.

Run the bed off the solid wall and purchase a rug which will fit appropriately.

Will you be making up this bed daily or is it for guests? Is it a child's room? If so, what age/gender?

Really don’t have enough information.

I think your first step is to define needs, then try different configurations (to scale) and usage will help define the better layout.

Child: dresser where suitable, low seating, nightstand, storage. I like bed situated like below, but depends on room’s dimensions.

If very young, a play area is important and I would place bed against a wall.

Youth: extra chair not needed due to desk/chair, open floor is not as important while functionality is. Consider combining desk/nightstand, which would allow for a dresser or bookcase.

Guest room: Two twins would be ideal, and all you need are some surfaces and storage.

I need to know meausrements of the the space and all the questions above answered .

I have a 12 ft x 9 ft bedroom with same configuration as Option 1. The bed is antique iron. I currently have a dresser where you have a desk designated. What type of desk are you going to used?

What about a daybed agains the back wall--the wall with the window to the right?
