As with any product like this there are pros and cons but let me just say up front this thing is amazing. I have three cats and one of them really hated my desk chair. I've been using a chair cover but it's been a new sense because it keeps falling down and has to be rearranged and it was just annoying. So I bought this after seeing it on amazon.I bought the navy blue large size. It came in a small package and when I pulled it out I was a bit concerned. There are no instructions but it is fairly simple to figure out. Just take your timeInside the item was a label that said l which I assumed meant left and so I went with that. It went over the chair very easily and from the photos I'm sharing you'll see that it fit well. I had a little trouble getting it pulled down under the chair and around but the key here is not to try to go over the hard parts of the chair just the cushioned parts. Pull it down between where the joins are. The zipper came together fairly easily. You have to kind of hang on to it and I have problems with my hands from arthritis so my problem was probably because of that. Anyway it zipped up perfectly and as you can see it looks great. Far better than the damaged fake leather that cats hate. The second thing I did is I use a stick in the space between the back of the chair and the seat to push the cover in place and hold it there. I did this with the previous cover I was using it was the only way to keep it over the seat. In this case it's simply makes it form better to the chair.Yes it is a fairly thin feeling fabric but it is a net and very stretchy. And for the price if it tears up you can buy another one cheaper than you can buy a chair. I probably will buy a second one so that I can remove this one when it needs washing.The cover is a navy blue and a bit darker than what you see in the photograph. I'm not sure why it comes out like that but that's just digital photography.Today is the first day I've used it so I will update if there are any negative changes. For now I'm happy with it
