“This is the second runner I purchased. The first one was to test if the mat "moved" over time. It did not so I purchased the 36x144 runner. My old mat inched every few days and I had to keep moving it back to its original spot. Laid down the 144" runner two days ago and it hasn't moved. Having knee surgery soon and was worried about tripping/falling on the older runner. This product is a winner for my safety. Easy to clean too.”
