On a basement carpet without much padding this mat is a bit more soft than I'd expect or prefer. Chair wheels make small divers which are easy enough to roll out of buy enough that it holds your chair in that position until you push your way out. This isn't uncommon with these cheaper mats but disappointinh none the less. On the plus side there is no cracking yet (1 week in)
Not a good purchase. Quality of material used is not good. In short time of purchase holes/dents in mat makes it hard to move office chair around on the mat.
