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.
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.
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.
