Square works fine when you have a lot of room. As AMCK pointed out, there ends up being a fair amount of space that isn't used or is un-useable because the table is there. For your living room coffee table, the best use of space would be a rectangle or long oval. Also, you wouldn't need more than around 2 feet for the width and that one looks HUGE at 3 feet wide. My aunt gave me a coffee table about the size of the one you are looking at and it ended up outside. It works great when you can put seating all the way around it on your deck or patio. I love round tables for dining. My kitchen table is round, so I can fit 6 or so people around it if need be. My dining room table is an octagon, so 8 can sit at once. It's a little cozy, though :) Both came from my grandparents. The octagon is really a game table, but it sat in their kitchen for years and years and was where all the fun happened! I love it even though it gives off a heavy pseudo-Spanish, 1970s vibe. That table is a great buy. If you have a couple of placement options it will be a great addition. If you like it you can always find a use for it, that's my motto!

I like your current coffee table although it could be a little longer. However a round one would be a little less painful when you bump your leg on it ----no corners!

I agree with these thoughts. I have a coffee table called the rotor coffee table, Italian and now discontinued. It has five stacked square surfaces that rotate so it like a moveable sculpture. What a beautiful piece!

Get a 42 to 48 inch ROUND!!! cocktail if you plan to leave that ottoman in place. You'll have a comfortable 15 or 18 inches of clearance, and no nicked knees or shins. Keep it very light and airy and open. Marble top on iron.....glass on iron or another metal. If wood? Round, Light and VERY open, no shelves etc. Anything else will look like a HUGE SOLID and heavy, "blocky" mass in your room. (Just one, of the many reasons I hate that sectional configuration). Boxes you in, quite literally. Maybe just go to bed? : ) Do NOT add another upholstered thing to that configuration unless this is your basement for the kid sprawl. Even this below." To my mind a bit boxed in but better than a big square. Alas......: )
