Comfortable and secure
I have a bench seat built in to my shower.  But, it becomes slippery during a shower.  This cushion is exactly what I was looking for as a secure option.  The bumps on top are not uncomfortable, and I have very sensitive skin.  I just received it  and have only used it once, so I cannot speak to durability over time.  But I am very satisfied with the safety component.
