The mat definitely stays in place but because the it's relatively thin and fairly flexible my desk chair still forms divots. The carpet we've got is semi-low pile but not very low so that probably doesn't help. I'm going to have to get a thicker mat.
Works fine. Was concerned if the thickness would be sufficient to support a rolling chair. It is a sturdy solid mat that works great for a rolling chair on a carpeted area. Would recommend and buy it again.
Mat came with the big Staples sticker on the shiny side instead of the back side of it. It left stickiness on there that I cannot get off no matter what I try. Also the mat is too soft I only had it for 2 days and I see indentations from the wheels.
