Good Afternoon,
Thanks for taking the time to write a review.
I am sorry to hear you're unhappy with your mat. As mentioned on our website, Turtle Mat backings are anti-slip and engineered to minimise movement as much as possible; however we cannot guarantee there will be no movement as there are so many different floor finishes and carpet finishes and piles.
Sadly, I can't find any details that this issue has been raised to us prior to this review. Please kindly contact us on info@turtlemat.co.uk and we will be happy to assist you further.
Kind Regards,
Turtle Mat - Laura
