I have a DR that is almost 13' square so mine is close to your size. My DR table (without leaves) is almost exactly 56" square. It looks great when no one is eating at it, but even without putting in a leaf (it will seat 5 a bit crowded, 4 better), it is hard to get around. I have a small sideboard on one wall, a chest on another wall, and no furniture on the 3rd/4th walls and it's still crowded. Serving is a nightmare as I cannot get behind the chairs to go around the table. If I put in a leaf (my leaves are about 24" wide), I can seat 6 comfortably. One Christmas, I had to put in 2 leaves, and the people at the end, well, one had his chair practically in the entrance into the LR, and the other was up against the french doors that lead to outside - it was awful and this was to seat 9 people! I cannot imagine how you can possibly use your table in this room, or any other table and hope to seat 10 people. It's just not big enough. It takes a BIG DR to hold a table that can seat 10 comfortably. My DD has a DR that is 15' x 16 1/2'. Her table is 52" wide and if she uses small chairs, she can seat two at each end and with two leaves in her table (a triple pedestal table), she can seat 4 down each side, thus 12 in total. One time, she seated 14 - it was very cramped - no b&b plates, single wine glass in the table setting.

It sounds like it would work. At least I think 18" is enough space for one to sit while all four legs are on the rug. I would even think in most cases one would be able to get in and out of the chair without having to move it off the rug. I've never put a dining table on a rug because of this dilemma. I Googled "60" round table on *' round rug" and found the link below where someone asked a similar question and another shared a photo of their 54" dining table and chairs set on an 8' round rug. Here is a link that might be useful: [Scroll down on link to see photo.

Funny the first pic made the light look soo off center. Anyways. You definitely should make a template on the floor and see. I love the style choice of The table you like. Really pretty. And I love how the room looks so far.

Does this exist anywhere? It would be perfect for my dining room but I can't seem to find any extendable round dining tables bigger than 60" in diameter. Perhaps the podium bottom wouldn't be enough support once extended...
