A wonderful room, well done, your glass collection is fantastic.
Either a chair in the same colour as lounge, with red cushions or a red chair. But either way I think it has to be a wonderfully shaped chair to match the glass ware shapes and abstract painting.

Or the blue in your painting so the predominant red glass pops

Thanks for your input

I think tan leather would look fabulous or you could pick up a colour from your decor items.

Or the Soor Swivel chair by Desiree. I just put it in a Living Room recently and I think it would go beautifully in your place. This fabric is not a custom colour but in the range on offer.

Thanks for feedback and interest. Where can I search these chairs

Would love to see luxurious velvet finish blue chairs like the king living boulevard chair. I chose blue because it is the complimentary colour to orange which you have quite a bit of in the room.
I would also consider putting a grasscloth wallpaper in the alcove where the tv is. You would need to find something that really makes the paintings sing. Beautiful space.

For the tv wall, in this example, a grasscloth wallpaper colour is echoing the artwork.

Thanks so much for your ideas

Your room is so light and bright, you have a wonderful balance of colour and neutral already! But you have a lot of light colours that make the room look as though its 'floating' and you have an impressive art and objet d'art collection with red and bold colours - so I actually think a couple of small accent chairs in a dark cognac leather or vinyl would work well and anchor the scheme, especially if the chairs were an open-arm timber design (like below image) so the timber matches with your existing TV cabinetry and coffee table and the open arm design does not look so heavy.

Also you have nice high ceilings so I wouldnt go for a chair that was high in the back, this would throw the symmetry of the room - keep the accent chairs about the same back height as the sofa

Thank you any suggestion where I can search these chairs

For an oak colour frame chair I'd try a Scandinavian style retailer like Icon By Design. But it's also worth while getting a quote from a local upholsterer in your area as #1 they often make the timber frames in-house so you can nominate your design and #2 your choice of upholstery vinyl/leather will be better. There are some awesome leather look vinyls available that cost less (eg Wortley Group vinyl 'Marlo' vinyl)

Little Thommo many thanks what you have described was in my head ! Really appreciate it. Cheers any other problems you may be my go to!!

No problem Maureen, best of luck!
