I LIKE THE MAT BUT WAS A LITTLE DISAPPOINTED WHEN I PLACED IT ON THE FLOOR AND IT WAS SMALLER THAN MY OLD ONE. YOU CAN SEE THE OUTLINE OF MY OLD MAT ON THE CARPET AND THIS MAT FITS INSIDE OF IT.
Looked down at the old mat one day and noticed that it was cracked in addition to having dimples where the casters would roll into when I slid forward. Decided that it was time for a change and since the old one (from Staples) performed well replaced it with a similar mat from Staples. Am also pleased with the new one.
