A fantastic and versatile sideboard designed in the 1960s by M. Polar and manufactured by UP Zavody in the former Czechoslovakia. The large unit has two drawers and a cupboard with glass sliding doors and the smaller unit is a drawer unit all covered in rare opaline black glass. As you can see in the photos, the smaller unit can be detached and used separately to the larger unit. 
 
The dimensions are: H: 820mm x W: 1755mm x D: 450mm
