DO NOT buy if you have a textured tub
In theory this item would be a good idea but there are two major flaws with it.  The suction cups will not stick at all if the floor of the tub is textured.  The mat will attempt to float and is very uncomfortable when it does making it unusable.  The second major flaw is the bubbles that the mat releases are cold which not only defeats the purpose of a warm bath when it makes the water cool down.  I will be returning this item.
