I am so happy, and relieved, to have found this bath mat! I love the large size, but mostly that it is made of rubber. It really stays in place, as it is heavy and has a huge number of small suction cups. My feet don't slip at all due to the surface texture, even when I use hair conditioner. I have been searching for a long time and have tried a handful of mats. One of them cost twice as much, and although very pretty, was almost as slippery as the tub surface! And you can't beat the price!
