Disappointed that it is very soft and does not stay in place. I have had others similar to this one purchased from Staples and they have been fine. Waiting for family to come and help life desk so we can anchor it in place in the hopes that it will stay put.
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
