The mats are good after a week or so of use. However they arrived rolled up in a box and took a long time to flatten out-- overnight with weights then under the desk chairs. These should be shipped flat. Other than the initial difficulty they are great-- they look nice and seem very sturdy.
Our librarian really likes the mat and I appreciate how easy it is to work with Staples when it comes to deliveries. You are very quick and efficient. Thank You!
