The mat "walks" on the carpet. I have to adjust it a couple times a day. I don't have a deep pile rug and the wheels sink in. I tried to save a few bucks now I'll have to spend more for a better one.
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.
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.
