Pair of modernist wooden sideboards

Pair of small modernist sideboards that can be converted into a bookcase or storage cabinet. Height-adjustable metal feet. The feet of one piece of furniture can be removed to place it on top of the other. A safety system at the back prevents the upper piece of furniture from tipping over. Very good general condition. A shelf in each sideboard. (One contains two glass holders). Total height of the piece of furniture in bookcase mode: 135 cm.
