The mechanism allows to transform a low coffee table to a full size table. The mechanism is operated through the uplifting of the double table top with one hand movement, at the same time a special support comes out, which receives the additional table top, opened on hinges. The mechanism work  is assisted with gas spring, adjusted to a particular weight of the table top. In this easy way the coffee table quickly changes to a table. For smaller tables we offer mechanisms with smaller dimensions - PT 007-5.
