The table was custom designed and built by the owners, a fluid transition is still a work in progress for this cool feature. Consulting a metal fabricator for options would be a good start, something pneumatic would be ideal but pricey. If you find a good solution come back and share!

Breitkitchen, did you ever find the table you were looking for? We are also going to build a corner banquette and would like a table that goes up and down, allowing it to also be coffee table height or dining height. It's in a game room area by an outdoor pool.

I would look at a supply catalog for campers and motor homes. This is a very standard feature and could probably be bought separately.
