Depending on the size and style of your room, having a gap between two accent chairs can make the space feel unfinished. Consider placing a small end table, chest, bookcase, or storage credenza in between if you want a place to display or store items and books. You can also set a large ottoman or coffee table in front to bring the pieces together or a large floor lamp between the two for extra lighting and contrasting height. Lastly, you can intentionally leave space for guests to walk between as a walkway into the room.
