This set of wooden furniture has 2 pieces with movable parts; one side of the crib moves up and down (see images 1 and 2 for the different positions), and the highchair tray moves up and down as well. You can see the different positions of that is the images as well.
The furniture pieces in this set are at least 25 years old and all of the pieces are in very good condition.
