Good quality fine for the intended use. Short term use in a "covid quarantine " bedroom office. If intended for a more permenant situation consider a heavier mat.
The hanging tabs created a problem as the furniture was precisely placed. The only way it fit was to turn it sideways but there was no lip for fitting under the desk.
My chair sank into the mat. It left deep indentations. One time i couldn't even rool out of the depression. The mat did not support my weight. I took it back and exchanged credit for other merchandise
