This is a modular version of the Lovesac Sactional Shoe that I designed. I ran into sactional layout that only required 3 holes and would leave the 4th shoe hole sticking out of the couch where it could be tripped on. This solves that issue. This allows you to build any combination from 1 hole to 4 holes.
