Love your style and you've got some beautiful furniture there! A deep aubergine purple velvet on your wingbacks would look stunning. I'd tend to stick to purples in this area to keep it classy. Also, a dark purple would be more practical with kids than a cream. I'd keep the chairs you've got, unless they are really wobbly. Get someone to check them out and give you a quote for repairs and then you'll have a price to work against to see if you can get cheaper. OnePlan is right on the style and yet I don't think they look out of place in the room. I also like the idea of bench seats or if you wanted something really different, you could get a church pew?! I don't think the room has too much dark furniture as it is a large light area. Keep us posted with pics/samples of possible fabrics you find. Also, check out fabric outlet places.

The chairs are a good match. Leather is probably best, great for kids' spills and accidents, but any fabric will do. Not sure on purple with green - those two colours together clash a bit for me. The green kitchen looks great, and I'm a fan of dark wood. The only thing throwing it off at the moment is the yellowish coloured walls. If they were repainted a soft white, this would make the green and the dark wood really pop, giving you a fresh and sophisticated, calm look which I think would work well. You could then upholster in a green to match the kitchen which would look appealing. Finish it off by some fresh white flowers as accents in the room to draw the eye and you've got a beautifully transformed space with a fabulous feature dining area :)

Unless buying custom manufactured wood cabinets, you are buying a series of boxes. A 100k euro kitchen installation of an Italian kitchen is one example from my portfolio. Differences are found in the hardware, the door/drawer pulls, weight of doors and exterior finishes. It is about the design, first. In our region, you can knock off 1200-2000 just be sticking with a full depth fridge--but it is design that will make it possible to install full depth and get a counter depth effect. In the Garden Oaks Fine Accommodation residential display suite I needed to prove that a high-end design can be executed for less. Again, it is design that does the trick. The owner of the kitchen above loves the pendants over the breakfast counter. I did not have the heart to reveal the price--$19 each. That owner likes/needs bling so the 14k euro chandeliers (2) in the foyer are a feature. But we get more comments on our pendants--because they are integral to the overall design. Real estate agents have pegged this kitchen at anywhere from 45-75k. It cost under 30k. DYI projects offer the opportunity to take the time that you might not otherwise allow to a designer (hence our need to come equipped with knowledge, contacts and suppliers that augment our services). I recommend drawing from images (Houzz is great for that) to start, then researching suppliers, collecting specs, and developing a document that covers all aspects of the kitchen from lifestyle needs to style to comparisons of product reviews. Whittle it down to an instruction for purchase and installation. Consider challenges such as the dreadful corner cabinet turntable and splurge on solutions that make your design truly functional. You'll appreciate the expense that delivers practical functionality. There are remarkable solutions for the corner cabinet--but my fav is to determine whether that space can become storage (cabinet or drawers) in an adjoining room. When not practical, articulated pull-out stainless shelves are functional--and cool. Undermounted sinks are great for clean-line counters. Well placed recessed lighting (design again) eliminates the need for other fixtures--and allows you free rein to purchase for focal point impact or (my preference) to fit seamlesly into the overall look. Enjoy the journey--have fun!

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.
