Our dining area is 10.5 x 11.5 feet and I'm looking for a round table to fit 6 small upholstered chairs all the time, and the option to extend it to fit a few more if needed. The two options are 48" round opens to 66" length oval, and the 54" opens to 72". I've been told by some that I can't fit 6 chairs with either size. Any help with the size would be appreciated.
