I was very disappointed by the quality of the mat. If you stand on it with bare feet, you can clearly feel the fabric. Guess if you have your feet wet, you will also see it. The floor is not tight enough. Sent them right back. However, noteworthy is an excellent customer service, which is approached in Eigenintitative to me, and told me, despite my subjective criticism, reimburse the return costs. I've never experienced.
