My carpet is only 1/4” with an 8lb pad. I only weight 170 and the mat has depressions each day where the chair wheels were. Not very good performance for a mat that supposed to be for a medium pile up to 3/4”. Not sure it’s going to last very long.
The 36" x 48" clear chair mat is the perfect size for my rolling office chair at my desk. I recommend buying one to save your carpet and making it easier to roll with a chair or have a stationary chair.
This is a replacement for a similar mat we had for a few years. It is not terribly rugged but works for our purposes. Not quite sure how to remove the tabs on the edge used to hang it in the store!!
