Absolutely love them  I had purchased my sofa and chairs only 3 years ago, but had rescued an additional cat who had begun scratching the heck out of the chair 
Even with every possible purchase of cat off / away etc 
So before it got any worse 
I got the covers my scratchy has not done it to these covers ( as yet ) super soft , comfortable and washable. The sizes are great and I have to admit I did guess on the sizes but I couldn’t be happier with my choice .Even considering getting an alternate color
