The Schmulb method allows for the creation of original designs in cardboard furnishings that can include large compartments or functional drawers that are extremely resistant. 
The super stability and solidity of this furniture is due to a unique under frame and system of construction.
Once assembled, there is no surface of the furniture that presents a risk of caving in or giving way. You can exert pressure without fear of damaging or deforming the piece, which is not always the case with other cardboard furniture.
