Poor durability slides around the rug under chair. Needs to be repositioned at least every 2-3 days. Wheels of chair made imprints in it on day one making it difficult to move around. Would not recommend.
It's described as being 36" x 48" inches. The description is accurate. It is described as being "Crystal Clear." It's more translucent than clear but it is exactly as I expected. If it is like the mat it is replacing it won't last forever but it will last for five or ten years. There's really not much else to say. But Staples told me they really wanted my review (I bet they say that to you too when you purchase from them) so here it is.
