The product is ok but all the floor mats seem to be the same standard size... I could use a larger one and putting two together just jams up the rollers on the chair when I try to move over the gap. Maybe because it's on carpet but then again if it were just another three feet longer it would be no problem.
Came rolled up so I could not use it for a couple of days. After that it worked fine however. I would recommend not using this on a hard wood floor though as it would scratch it. It is great for my carpeted floors though.
I'm using the chair mats in my sewing room which has berber carpet. I'm hoping these will hold up better than ones I've purchased in the past. The old ones cracked and chunks broke out of them after just a few months of use. These are really smooth and easy to clean and chairs roll really nice on them.
As it is thin chair wheels sink in at take a "set " which can make it initially hard to roll the chair. I suspect this will lead to it breaking down (they all do) faster needing earlier replacement. It is a nice size. The thicker (and more expensive) ones were much bigger.
