Drives me up a wall

In 2008, furniture designer Lila Lang sofa presented this sofa at the Parcours Saint-Germaine exhibition in Paris. It became a sensation, showing up in many home decor magazines and circling around even more (every?!) home decor blogs. I read an article about it again last week (apparently, it's one of the most monumental furniture designs in the past decade) and all I could ask was... WHY?  I just don't get it.
