Adjustable desks are a new concept...or are they? Not all brillant inventions were made in our day though we would like to think so.
This drawing is dated 1797. The table is designed by David Röntgen of a famous French/German family of carpenters. They didn't call themselves furniture designers. This illustrious title had not yet been invented.
Apart from its somewhat old-fashioned legs, this table might be a modern construction. It has most of the elements of a high-tech elevator table with numerous possibilities of adjustable heights and angles.
David Röntgen knew all the principles 200 years ago: a work table must allow the user to change position frequently to protect the joints and muscles of this body.
