Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

It is my understanding you are not going around the corner but on 2 opposites sides of the space . The only thing i would be concerned with is your bedding and if you want to hang art on the wallpapered wall. Ilike the wallpaper and I would choose the lighter green and maybe try and find some faux silk drapes in that color . A nice crisp white matlesse with a lime throw and lime, blue and white and maybe a bit of pink pillows would be nice

Sree, There are so many products that can be used for finishing a TV unit. Laminates, Veneers, Glass, Charcoal, WallPaper, MDF, Duco, PU, Wooden & Stone Claddings .. just the few that come to top of mind. But what is that you wanted to understand about these. Thanks, Nitin Cornerstone Designs, Bangalore.

Kelly, if you would want it to appear in the center, you may have to add a mirror half way up on the left wall. Adding long barn shelves on the back side will add to the centered look. The shelves should touch the mirror for a seamless look. Back wall can be spruced up with handmade tiles. Thanks, Nitin Cornerstone Designs
