Extension table - patented system from this famous Danish furniture manufacturer, where 1 person can extend the table. Slide it out and two folding parts come up. This increases the length from 1.80 m to 2.75 m. Width is 100 cm. Possibly with four matching chairs. New 3600 euros. Now in already disassembled condition pick up in IJmuiden for 1500 euro. Is in undamaged and hardly used condition, because it was more of a statement piece. The pictures show the table 'in action'. Purchased at the time because of the obvious Frank Lloyd Wright influences. Also suitable as a conference table.
For a demo video, search the internet for Skovby Dining Table SM 19. Note how cleverly the ends are supported when extended.
