Thanks for the opportunity to look at your room and think about what I would do. It has been fun. I think the round coffee table will work if it is large enough for everyone seated in the L sofa arrangement to reach it. (Bonus is no barked shins from sharp corners on a square one.) I agree pale colours like yellow won't do much for bringing about a changed more modern look. The room needs more drama and freshness and I think that currently the room has too many colours in the pale range and not enough contrast. I would go for introducing more of the stronger colours in your attractive tribal fabric, including black and white. Black in particular will allow you to really update the look. Consider painting the bookcase or even the doors black. (The existing coffee table would even look good painted glossy black.) Some plump cushions in the tribal fabric and others in a bigger more graphic design in large red and white zigzags or stripes say, would add to a more integrated look. Your bright yellow pot plant holder on the bookcase is another colour in your tribal fabric which would look good in the scheme as a minor accent, say, more pots that colour in a larger size, a big vase/artwork or lampshade. My advice is to stay away from golds and beiges as they relate to older fashions. A large framed in black graphic print on the wall in black and white (or even photo with meaning to you) could be an idea to think about too.

Thank you everyone so very much for your responses and advice. I liked the idea of having a bold piece to tie the church in but like a few have mentioned, something simple might be nice to not overshadow the pieces we've collected. The Nick Cali nesting tables might work quite well, simple but still have the raw wood and we can move them around. I also like the idea of a round table. Annb1997 we actually looked at the carved coffee table, it's super cute and pretty it's a shame that it's just a bit too low to be functional with the sofas. We are probably looking at something around 45 cm in height...but we might still get it anyway and add it into the library nook. We move at the start of Dec, will post photos :) Here's one of the current owner's layout. Thank you again everyone you've been amazing!

Ok if putting coffee table I would put rug under table if it is sitting on the carpet not in lounge area
