The only reason I didn't give this 5 stars is because it's made of plastic so I know it will eventually break (as did my last one); however I expect it to last a long time as did its forerunner (at least 2 yrs). I like the small size as this is used in a small room so I don't feel overwhelmed by the size of the mat.
I decided to save money and bought this flimsy mat. I see that the chair is already leaving marks that don't go away. That's why I retired the old one I had. It makes it difficult to navigate the chair when there are dents that don't disappear.
