The material is soft and plush. Easy to install, even if you misalign they pick up and can be relocated easily. 
I do however have 15 steps so I had to leave one of the stairs at the top empty. 
These are newly installed so I'm not exactly sure of the durability or how long I'll keep them on. I do feel these are more expensive compared to the other stair treads and would like an option of 14-16 when ordering.
