Thanks, everyone, for your responses! Haven't quite nailed down which chair it might be. One possibility is the Quinn chair - I like the rounded shape with the very squared-off sofa, and it's pretty comfortable. Or I might go for a more substantial comfy chair, even the York chair that goes with the sofa. I guess knowing exactly which chair would help. Sigh. Les, I agree that the abstract print isn't ideal. It seems that my taste in fabrics is slightly out of date - a few years ago, there were all sorts of great abstract prints in the stores (as well as sage green sofas), and now that seems to be going out. Amy, I think what bothers me about the patterns on the right is the limited palette. The neutrals and reds together are too, uh, spicy. They feel like they need the green to make them calmer and more soothing. OTOH, a green-only palette would feel like it needed red to liven it up. (Plus more colors so it doesn't end up looking like Christmas decorations!) I liked the combinations of colors in the rug because they all balance each other. And yes, it is Mask Earth on the left! Mask Sun felt too bright, though maybe I should take another look at it. I do tend to like more muted colors... though a lot of them. ;-) The Moon fabrics are pretty, but the colors didn't really work with the sofa. Mirror, too - I looked at Mirror Crimson & Mirror Mink, but they weren't right. And, no, I don't have the art yet. It's just a concept. I feel like if I can't find the right painting, I'm just going to buy a big canvas and a bunch of acrylics and paint it myself! Here are some pix of the sofa & possible chairs: Room & Board York Sofa Room & Board Quinn Chair Room & Board Eugene Chair And here's a chair from Macy's that I think is too large (it's going in front of a window), but that I like the fabric a lot:

Oooooooooh, dover, that denim wingback is good! Sooooo goooood! Dang I want one now, lol. I agree with becky... No way can a wingback chair really look "too casual." Same with a Chesterfield. You could cover a Chesterfield sofa in dark indigo denim, and it would still be pure awesomeness, even in Buckingham Palace. And should it be a solid color denim and what color? The darker, the more formal. Solid, too. If you go with a lighter denim, or a denim with a pattern (stripe, plaid, embroidery), it gives a more casual vibe to me. [Disclaimer: I am not a pro. Just some random crazy internet chick, lol.] Edited to add: Just saw the yellow gingham chairs. Those are pretty nifty, too. :-D

A dining rug should be a minimum of 4' larger than your table top so there is room for chair scoot and sit. No one wants to have to get up and let someone exit the table, so there should be room behind seated guests for one to exit behind them. Rugs also should not run into walls or furniture against the walls. Or are you just advertising for your business? I'm known as the Re-Design Doctor.

Or - maybe not with that fabric or cute bow, but add soft blue which seems in rug, playing with neutrals. This might be too puffy to lay down the center of ivory chair [under current pillow] Other colors: moss, red..
