I work in a high activity workplace lots of hustle and bustle and chair movement. Our floor happens to be tiled with deep grooves for the grout in which our office chair wheels would get stuck in. Very annoying. Other chair mats we had would slide all over the place making them a safety hazard. This one sits in place actually nice to walk on (softer feel than tile) and so far provides a smooth rolling surface. The large area allows for not sliding off any direction I decide to roll too which is even better. Go big or go home!
Even on a flat pile office carpet this mat was too soft. Dents would form where my chair had sat even if I wasn't sitting in it at the time. I chose to exchange this for a firmer better quality and slightly larger version.
This chairmat is used weekdays and holds up well for it's heavy use. It doesn't get noticed which is how this type of product should work! We always buy them again when they eventually wear out but it takes a long time!
