These stay in place and look great.  I was concerned that they would be too thick and our knees wouldn't clear the table but not problem at all. Love them! Update 7/30/16. Unfortunately, two of the four required stitching up at the front seem.  They have also become quite flattened.  My husband and I are not petite but not big people either. I'm still using them as their primary purpose is to protect my wooden chairs from scratches.
