Arhaus, like Restoration Hardware, and Pottery Barn have lots of stuff that looks good, looks fashionable, but when compared to other lines, not well made or comfortable. Look into (for about the same price) Taylor King (Portfolio Collection) where you can build a sectional pick your arm style, base options at no charge. $6300 for a 110" X 110 " sectional, 8 way hand tied, solid Maple frame. No down, down extra. Lot of fabrics to choose from for that price. Henredon, Fireside same options, grade C $7499 (Spring Blend Down seats, Down Backs, 8 way hand tied) 10-15 fabrics for that price. Flexsteel, $5000

I'm sorry to take so long to reply. I've been out all day! Thank you for the pictures. Your fabrics are really beautiful! I do think that you could use the welting fabric for the chairs and welt with the valance fabric. I'd probably do the reverse though to match the valance, and maybe add a small green back pillow to the chair to contrast with the red and again trim with the valance welting too. You can't miss with either direction you go. A green chair would be really beautiful too especially with the contrasting welting. I'd do whichever version would allow for moving the chairs from room to room easily to go with what you have going on in the rest of the house. This may not be a big consideration for you though. I'm so glad you already have the parsons chairs. This really makes for some significant savings doesn't it? There is a site you might want to look at that does parsons chairs in every possible way with a variety of different legs and finishes, arms and armless, skirted and unskirted in their fabrics or your own. Slipcovers too. The site is Carrington Court Direct and lots of designers use their chairs. If you look them up you'll see that there are quite a few design options that most of us have never seen before in terms of parsons designs, two of them being the Danbury parsons wing chair and the Dartmouth King chair. Men like the extra width of the King design for a dining chair and the Danbury is a style that lots of people feel comfortable moving from the dining room to the living room. The Danbury arms work well for pulling the chair closer to the table in tight circumstances where otherwise armless chairs would normally work. I don't know whether a skirted look would be something you're interested in, but I've seen these Danbury chairs upholstered in both solid colors and patterns with a contrasting welting and a third contrasting color or pattern in the kickpleat of the skirt. Kind of an unexpected surprise. They look much more expensive than they are I think, and all of these chairs are very good quality. Their upholstery workmanship is first rate according to everyone I know who has used them. Just another option to consider...as if you needed one more! Great site for inspiration though. Having parsons chairs already on hand is really wonderful for you and I don't think you could go wrong in covering them in either combination of the valance materials or the green and adding a small pillow would be icing on the cake. I know I've seen your beautiful wallpaper in a fabric somewhere too. Your dining room is really charming and very French!

Check Room & Board, which has more modern styles than others. Be sure to click on each sofa option because they are generally available in multiple sizes, including down to twin and double beds. http://www.roomandboard.com/catalog/living/sleeper-sofas Lots of options in leather and fabric. I highly recommend looking specifically at the ones that are made by "American Upholstery/American Leather", because they are as comfortable as a regular bed but also good as a sofa. We have the Berin, and have no problem having friends and family sleep on it (at worst, they describe it as similar to a "firm" mattress). It's in our study, and i often hang out on it as a sofa - and it is very comfortable. American Upholstery is generally considered the gold standard of comfortable sleeper sofas, so their venture with R&B (a modernist store) is probably exactly what you're looking for.

I’ve had custom furniture made before, and I agree that it’s not necessarily more expensive, and it’s a great option. I think it’s a much riskier undertaking with a sofa however. Subtle variations can make a huge difference in both looks and comfort. I think it’s fine if you see a sofa you can try out and examine and then just make it a bit longer or whatever. But cobbling together a custom sofa from, say pictures, is risky in my opinion.
