Experience the most durable chair mat on the market with this Chair Mat for Carpeted Floors! Here are answers to our customers’ most frequent questions. <br><br><b>WHAT IS THIS MAT MADE OF? </b><br> Our chair mat is made of 100% polycarbonate, making it the strongest and most durable chair mat on the market! The mat’s surface is super tough and thick, so it won’t break or curl. Because of the mat’s strong and solid surface, your chair’s wheels will easily glide across the mat, without scratching, sinking, or leaving indentations. <br><br><b>WHAT TYPES OF FLOORS CAN I USE THIS MAT ON? </b><br> This pad is ideal for most carpets (even high pile carpets)! The studded underside of the mat helps to keep it in place. We recommend following your carpet manufacturer’s directions before use to ensure the chair mat will not harm the carpet’s surface. <br><br><b>IS THIS SHIPPED FLAT OR ROLLED? </b><br> We ship our mats flat! Don’t waste a minute unpacking your chair mat. Simply take it out of the box, lay it flat, and you’re ready to go!<br><br><b> WHAT SIZE IS THIS CHAIR MAT? </b><br> The mat measures 36” x 48” with a lip, making it a perfect size to fit under most desks and protect your carpets. <br><br><b> CAN I CLEAN THIS MAT? </b><br> Yes, cleaning the mat is easy! Simply clean with water, rinse and air dry.
