I looked up outdoor tables in Travertine / Marble. Found a company in a different state to where I live that imports them from Overseas. They showed many designs from Italy but I picked an abstract in sand coloured Travertine with marble, abstract, angular pattern centre with modern design in black , white & choc. At 150cm round , 4cm thick , weighing 75kgs. Rock solid and looks beautiful with natural imperfections in the travertine ( a little rustic ). Can imagine it useful for many generations.

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.
