The stair treads are nice. The color is a little darker than what I wanted but acceptable. The thickness is also as described. 
We have purchased some double stick carpet tape to add to the backing as my cats end up flipping one or two as they race up and down the stairs!!
I am satisfied with the product and would buy them again if needed.
And delivery was a day early.
Shopping at Wayfair is very easy, just too many choices!
