Gently use some upward force but no more than necessary to get the leg off of the floor in order to bend the leg. Once the leg is bent you lower that end of the table towards the floor. That motion should bring the clips out of the bar on the wall and allow you to complete lowering the table to the “bed” position. NEVER LIFT UP ON THE TABLE WHILE THE CLIPS ARE IN THE BAR ON THE WALL.   To put the table back up, reverse the process, starting with the end closest to the wall.
