The folding trestle makes it easy to handle the base units. For use, the base units are taken out of the wall storage unit, unfolded and placed where desired in the room. Then the top units come out of the other wall storage unit, fold open in the middle with hidden Soss hinges and register onto pegs in the tops of the trestle bases. Once in place, the tables are very sturdy and rack free. This is a great solution for a great-room where you do not want large tables to take up entertainment space except when you need them.
