For me, yes, it seems a bit odd and there's a lot of "circles" happening - area rug, coffee table and foot stool. What do you mean by rectangular was awkward? Another option would be a large oval perpendicular to the fireplace so both the sofa and armchair feet are anchored.

Thank you Andrea. I will try that. The rug does come in an 8x10 oval.

Too small. Needs to be twice as big.

I agree with oval.

Update: Large rectangular much better!
