And a pale aqua dhurrie rug at pottery barn that works with your pillows:

I think you need nesting coffee tables.

Please do not buy a rug to match your pillows. It should be done the other way around. The rug should be the foundation of the room. Then build everything else around the foundation.

Accessories & paint should come as the accents to the rest of the room's furnishings.

Lila those coffee tables are just what's needed in a space this large! Can you tell us the measurements of the open space between your sectional and chairs?

Looking at the size of the sofa, I think that 2 rectangular coffee tables will fit the space or get 3 round ones. Looks like you need at least a 12/14 rug to tie the chairs and sectional together. Please don't get one too small.
