Perfect size for in between Autonomous desk legs. Chair rolls nicely. No problem rolling around in chair after 15/20 minutes or longer of sitting. Had to lay it on floor for 2 days before final placement. Thankfully the sticker came off easy with no residue. Great product. No complaints.
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.
I would have preferred this pad be thicker as I placed it on top of thick carpet. For the moment it seems to be doing fine supporting me and my desk chair.
I had to replace a chair mat that I had used for many years and this was the perfect replacement. I always get great help at The nearby Staples store and I got what I needed.
