Query: Comfortable, but falls short

This fitness mat is thick and cushy, but I find myself having to make a lot of adjustments during my workout because it's about a foot too short. My biggest complaint is that the 'washable' cover (a major reason I selected this product) shrank to a completely unusable size when I washed it (in cold water, line dried). Now I'm left with just a piece of foam that is inconvenient to transport and somewhat uncomfortable.
