It seems harder and harder to find good quality extendable dining tables these days but we have a clutch of them on the D2D website - here is the Denver oval oak table that extends from 1.67m to 2.07m using a butterfly mechanism.  The Denver is particularly solid and made from particularly nice oak as the closeup pictures show. Despite this, we sell this extendable dining table at a very reasonable price that should make it affordable to the vast majority of customers.   Here are some lower quality images that at least show you the table in the closed and open positions and also with some leather chairs.  There are many leather style chairs on our website that can be ordered with this table
