It's a good value for a small space. This mat isn't huge but for a small space it does a great job. Chair rolls smoothly over it and it does protect the floor without calling attention to the mat.
I don't know if any other mat would be better--I just noticed this mat's info says to use with short commercial type carpet and I have thick pad/carpet. My chair does not roll easily. Probably my own fault for not checking the details before I purchased.
