This was perfect for my home office. It is thin enough to still show the carpet underneath - in fact unless you know it's there you don't notice it - yet durable to let my chair roll around on it. It suits my needs perfectly.
I am using this in my home office. I have it on a deeper carpet than the product recommends but it works ok. It doesn't slide and my chair rolls better on it than on the carpet. It's not the best rolling surface but I am on a tight budget and it was a great price. All of the other similar mats (or even smaller ones) were MUCH more expensive and I didn't see the need for paying so much more. This isn't the best thing since sliced bread but it works for me and my situation.
I purchased two for the office just for the high traffic areas where the chairs tend to move alot more. Every time i get close to the mat the corner tends to ride up alittle and well there i go falling on to person next to me.
