I would suggest round to break up the hard angles. Maybe pull the love seat out from the window/wall a few inches...Pretty room from what I can see!

Have you looked at tales here on Houzz? Might find some leads on the right table there. With all the dark floors and furnishings, consider something fun for more of an accent that just a regular old square end table. What is your style? Hayneedle has some cool tables. I'd suggest an area rug to fill the space in front of the FP with some color and movement.

I think you need something besides wood or brown in color like the sofa's. I would suggest a metal leg table with a stone/granite look top in a lighter color tone. Square ,round or rectangle would work. Add a tray to the ottoman for table service to. Then add end tables at the end of sofa's Maybe 2 matching and one coordinating one. I would add a colorful rug for the seating area and a Ceramic lamps in a accent color on the table. Add toss pillows to the seating. The room now reads as brown and white and all solids. Try to bring pattern & texture in to the room. Good bones but the finishing touches will bring the room to life. Add some large accessories & plants too. Retired Decorator ,Kevin

I, too, would select a round table so that not everything is so square in the room. The one shown below not only offers an interesting copper top, but a nice modern base. I recommend having a glass top made to fit the copper so that it is protected.

Thank you!! We just moved in so we are still purchasing the fun accents: rugs, lamps, decor! Thank you all so much!!!

I love the chrome and wood combo on this side table from Bernhardt. Its 25" Diameter, and 24" high

Maybe something like on of these? [houzz=]

Agree with great comments above - a round table would be nice to break up the straight lines in the room/furniture. Combo of wood + metal would be interesting, example Riverside Stone End Table from Hayneedle. The floors are a great color - put in an area rug to introduce color and pull through with accent pillows on your loveseat/couch.
