This product is under my office chair (a high backed task chair)at my computer desk on laminate flooring. It stays put and allows for some control over chair movement (i.e. chair doesn't 'take off' or slide as it does on laminate floor.)
I have only had this chair mat for a week but so far it is living up to the claim that it will support the chair and not dent in. It arrived in a flat shipping container.
