Your design scheme has a very traditional European feel. I would continue with this and look at a couple of Louis chairs. The link I've attached shows one with a mix of rattan with an upholstered seat cushion. You can also get them with an upholstered back and arms. However I quite like the rattan for contrast so it's not too matchy matchy with your sofas. http://www.canalside.com.au/productimage.php?product_id=115&current_image=1 You could then add a scatter cushion to the chair. Have you thought about also adding a couple of scatters cushions to each sofa, in a silk or silk like fabric. Check out Kaz's Samara range. Not sure what colour to recommend as I can't see your wall colour clearly but black goes with most colours. Oskuee's rugs are lovely, just make sure the colour ties in with your colour scheme. As you have plenty of dark timber in the room already, consider a glass and metal coffee table and lamp tables in a gold finish. Gorgeous crystal or mirrored table lamps and an ornate gold framed mirror over either the chairs or the sofa to finish off the room.

I think it would cost a lot if you could even find someone to do it. it would also be damaged by the outdoor weather so would look patchy and probably need painting. Probably best to purchase new one as much as i like natural there are some good replicas which are made to withstand the weather.

I agree it's a fantastic house I have a similar one with updated kitchen etc, Removing any swags and the painting done this is a more updated look. I'ts a shame that it's empty, how much would it cost to get someone to style a couple of rooms, kitchen dining lounge and take a few great photos for the purpose of selling, you could enlarge and frame some to hang on the wall so that you wouldn't have need to keep hiring furniture. Kitchen table chairs and a large choir rug, lounge with coffee table and a couple of lamps, no clutter would really help. Where do you live we could all come by and help!

I have some 60s TV chairs that recline, I love them because they are a bit retro and suit my dodgy back. I had them reupholstered at the very exorbitant cost of $500 each! They are now a fabric I love but, as someone else pointed out, went from squashy and comfortable to hard foam. I'm spending a lot of time sitting in them to soften them up ;) Also one of them had a higher back, which fitted my 6ft partner, but when they came back they were all the same height. My fault as I should have talked it through with the upholsterer. I would do it again but only for furniture I really love, and I'd be very clear about what I wanted. On another note, we had 2 club chairs made for us more than 20 years ago - we love love them and they will be good as new for a long time. It was way better than reupholstering 2 old club chairs.
