Im sitting on a Staples 5 spoke base choir with 2 rollers on each spoke. I weigh today 153 lbs. & the wheels still sink in to the chair mat ...making the chair harder to move! dcg
Floor rep inquired if I needed help. I told him what I was looking for. It was not on the floor but he looked it up & saw it was in the back. He went and brought it to me. What more could you ask - perfect experience.
Size too small for me Frequently rolling over the edge and then having a difficult time rolling back onto the mat. There is a slight pile to the carpet ... maybe to much for the mat type.
