Not much better than no mat - needs to be thicker and more rigid. It’s so thin it must be kept flat or it will be bumpy or fold on itself. I would not recommend.
The mat works almost too well. I had some difficulty in placing it fully under my desk because the little pins close to the carpet are hard to move and thus edge the mat under the desk. But once placed the mat stayed put and works really well.
It was delivered in a tube but unfortunately it was wrapped with the rough side out. It will not lay flat after using it for 2 weeks. The quality seems nice so I will return for an even exchange.
The mat does the job. After I watched my wife struggle with a straight-backed chair to provide her with a small office I lent her my roll-about chair and mat I had bought at Staples a couple of years ago. She like both so well that we returned to Staples and bought another chair and mat. She likes both and finds the chair to be more comfortable and the mat to permit ease of movement.
