Unfortunately the TV placement in relation to seating and the fireplace issue strikes again. Also it looks like you have one chair too many for the size of the room and the number of other pieces you have. I'm wondering if you an move the TV console to the corner where that chair and a half is at an angle. Move the chair so it sits across from the sofa. Move the chair perhaps to another room and then you will have room for the second end table. You can have both flank the chair and a half to extend" the length so that it now mirrors the length of the sofa. You will need to re-arrange the wall decor too
