No. I think that book case would look good. It has great lines and the arch at the bottom eliminates a heavy feeling that can occur when the wood goes to the floor.
I like the bookcase. However, I have a question about placement. I worry about placing furniture like this over heat registers, both because I don't want to interfere with airflow and because I worry it will damage the wood. Does anyone know if there are rules about how high things should be over the register? I have unhappily placed higher tables over them in the past. I would worry that the bottom of that cabinet is too low. Am I worrying about something I shouldn't?
