Inspiration: Floating Sectionals

Back when I was couch shopping almost a year ago, I remember considering IKEA's modular seating options like the TYLÖSAND line.  However, I changed my mind when considering that the sofa as a whole might not fit my space, and separating the pieces might look odd.  But after seeing Florence Rolando's floating IKEA sectional piece elegantly featured today on Design*Sponge, I might reconsider this assumption.

What do you guys think?  Would you float a sectional piece as a free-standing seating option?
