Can these mats be easily cut with a utility knife (or similar) to fit around any odd room shapes?

Our EcoRX Rubber Mats can be cut with a sharp utility knife and a straight edge, but we wouldn't say it is easy. These mats are very thick, so you will have to make a few passing cuts to cut through the mat. You can also use a large bread knife or a bandsaw to cut these mats as well. Always make sure to measure twice, cut once.
