I purchased this mat to replace one I'd had for over 15 years. Sadly I went off price instead of quality or reviews. This is a basic mat but it does not stay in place and moves around as you move around on your chair. It is on industrial carpeting as was my other mat but this one does not have any cleats so there is nothing to hold it in place. If you can afford more I would go for one up. I'm reordering with another company that offers a cleated one for less.
The product was shipped promptly - with a cardboard wrap that was 8" too short so it stuck out. No issue however as it wasn't damaged - just uncaring and unprofessional. The stickers on the mat were attached with adhesive that was difficult to remove. Even with spray Goof-Off removing the residual adhesive was time consuming and much more difficult than it should have been. The web specs said that the mat was for carpet up to 3/4" thick exactly the thickness of my carpet. Upon delivery the tag said it was for berber carpet (not mis-shipped - the correct item number). I believe berber carpet is typically thinner and more dense than pile carpet. The mat is 'soft' and my chair sinks into the mat making the chair difficult to move. The mat might work better on berber carpet so the fault is with Staples for providing incorrect specifications.
