So far, so good!  This is a substantial canvas cover with a rubberized waterproof coating on the inside.  It has multiple backpack-like connectors to attach to the legs of your sectional, and grab loops for easier placement and removal.  It’s fairly easy to unfold and cover the sectional—a little harder for me due to the placement of the corner of my sectional.  Lots of Velcro attachment points marked by orange guide arrow labels to aid in folding this “Storigami” product.  Instructions  care sheet have a link to a folding video which I have not yet viewed.  For reference, manufacturer measurement of my sectional is 100”w X 100”d X 29”h.
