Crate & Barrel scholar round dining table, $175. See it on the C&B web site here.  29x5 x 42 inches. Seats four comfortably, we often had six at the table.

A year and a half old. ​Lovely. Sturdy. Some scratches on the tabletop, which I retouched. I might add a coat of clear poly if you have young children. (Detail photo shows scratch before retouching.) -- no chairs; just the table.
