This cover is a perfect fit for our L shaped sofa patio furniture. We’d purchased a few different off-the-shelf covers that never fit properly, so it was time to order a custom cover. I was a bit worried with all the complicated measurements needed, but we followed the directions, noted specific edges where we wanted zippers or closures, and it arrived exactly as we imagined. If I remember correctly, I even added a few pictures of the sofa to my order. We’ve actually purchased two of the identical covers in different materials. The first, was ordered in the heavier material. It was not the right choice for us. It was heavy and difficult to fold and store. It was a 2-person job to remove and fold, or replace. For us, we leave the sectional covered when rain threatens, and uncover it and store it when not. We also take the furniture in for the winter (New England) so we didn’t need the heavy duty winterized material. Based on our first cover (which was also a perfect fit…just too heavy), we ordered a second one in the medium grade material and it’s absolutely perfect. We added another couple of corner zippers for ease of removal also. It is sturdy, waterproof, and easy to remove and fold, and just as easy to quickly unfold and put back on when rain threatens. Great purchase and it still looks like new after a year in the sun and rain.
