"Perfect for my daughter to practice tap and ballet on. We are using it on top of carpet and the edges in snap with too much weight applied to them (my husbands weight) because of the give in the carpet. We chose the darker color and love it. The snap on border is great for preventing stubbed toes. We got 12 tiles so it's 3x4. It's perfect! Also the sales rep on the phone was amazing! Knowledgable and made sure I was getting the right number of male/female clip on borders and corners. Fast shipping! Had the Mat in 3 days." - Sarah https://www.greatmats.com/tiles/raised-floor-tiles-max.php
