I set out to find the largest furniture cover available on Wayfair and found this product. It still isn’t big enough for my L sectional but it is a big help In protecting my cushions. The picture from the manufacturer has The cover laying so neatly over the L sectional and somehow defies gravity and forms a perfect square with no support on one side. Mine didn’t lay so neatly but it does the job regardless. Perhaps my sectional is oversized, but it appears to be a standard size that I purchased from Wayfair.  I found that by placing the cushions from the other chair (that wasn’t covered) under the cover as well, it added more structure to the cover.  I found the cover really well constructed. The corners are reinforced and the fabric is very thick. The clips are very sturdy as well.  Regardless of it looking a little sloppy, it does it’s job well.
