This is a lovely, thick, quality rug.  The colors are even nicer than the photos.  The grey is soft and warm and goes perfectly with our tile plank flooring. I bought a set of three for the main entry area.  The large rugs heavy enough to not slide. I added the sticky-grip tape to the ends of the small one at the foot of the stairs.  

The only thing some may not like is that with these being wool, they do release a lot of fibers.  Not optimum with crawling children.  It's important to give the rugs a very thorough vacuum before putting them down.  Then, especially if you have pets that love to roll on them, you'll need a weekly vacuuming (more when your pets heavily shed).

I fully expect these to last for many years.
