Width-wise, my living room rug starts an inch or two from the hearth on one side and ends a couple of inches under a bar on the other. Because of the hearth, it is about five inches off center in the room. I have found two chairs that I like, but I'm afraid they're too big. If I center them with the room, they probably fit fine, but if I center them on the rug, one ends up very close to the bar or they're too close together. In the photo, the pink chair is about the size of the chairs I'm interested in, and the paper bag represents the size of the second chair. I guess my main question is, do the chairs need to be centered on the rug or can they be centered in the room, even though the rug has a symmetrical design and an obvious center? Secondly, does this chair size seem to large and would I be better off with something armless and smaller? Thanks for your time!
