I purchased to use in my home office to protect the carpet as I slide my chair away from the desk. The shape and size work well providing a good fit for the "tongue" under the desk and a large protected area under the chair. The material is translucent plastic which is highly durable and let's the carpet color to show through. The bottom has little "spikes" that keep the mat anchored securely to the carpet. This is a well made product that serves it's utilitarian purpose well. I am fully satisfied with the product
