These covers made my old ottomans look so much better, I am very pleased.  They fit great because they are litterally a large square of material that drapes over the top and a skirt on an elastic band that wraps around most any size ottoman.  My ottomans are very old and so not real big, but these covers still fit just fine.  They would also fit a much larger ottoman.  Since the covers were so easily adjustable, I actually decided to put my ottomans up on bed risers and slid the skirt down a little so the ottomans are now at a much more comfortable height.  The material is heavy and hangs nicely.  They are machine washable.  As I said, I am very pleased!
