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.
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.
