My fault for not measuring first but this is about 6" more narrow than the last one I had and that 6" makes a difference when swinging (or trying to swing) the chair around. Also mat is too soft and chair wheels sink in.
This is a decent mat best used for hard surfaces or very thin carpet. The thickness is minimal & if you are of decent weight on moderately thick carpet your chair wheels will sink somewhat into the mat. I am able to slide around alot better than without it & it's better than nothing. A thicker mat is best for thicker carpet. Not sure how long it will last though. It's good for the price I paid though
This chairmat does not match the slightly smaller"standard" chairmat that I bought at Staples. It works. I do like the size but it's not smooth. The chair doesn't glide very easily makes a rumbling noise and when I'm barefoot the texture is like walking on concrete. It's also not as translucent as the "Standard" chairmat which means it is more visible on the nice hardwood floors. And as stated in the description it's square and it has a "cliff edge" which means it doesn't have the nice taper region on the "standard" mat. That makes more of a difference than I thought.
I use this for our small home office it is small and adequate but with our thicker carpet it tends to give under the wheels of the chair. Would reccomend this be used on shorter carpet.
