I have purchased 2 of these in the last 3 years. One began to crack and turn brittle within 6 months. The other is about 2 years old and has to be replaced because it has pretty much disintegrated. I would not recommend this. In particularr don't use any kind of commercial cleaner on it as it will turn brittle and deteroriate faster.
Using this on recommended commercial carpet without padding but it's not thick enough to maintain a level rolling surface. Probably OK for super-thin carpet.
It bends easily so simple to handle and lay down. At the same time it's softer (more pliable) than it should be so indentations don't entirely spring back from chair casters even when first in use. That makes for a bumpy rolling surface over time. The one I replaced with this also Staples' cracked over time.
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.
