So far so good - after just a week or two. Shipped flat so easy to start using without having to work to get it to be flat. The nubs on the underside are shorter and not sharp as compared to most mats - so no chance of scratching yourself badly. t does not have a lip - which I love. I got this one so I can slide side to side and still be on the mat - and to potentially have two chairs side by side on the one mat.
I purchased this mat to replace a Rubbermaid mat that lasted about 20 years. The new mat is of very poor quality and extremely thin. It sits on low pile carpet but my chair sinks into the mat and leaves divits. Of note is that I weigh 165 pounds and my chair has smooth plastic castors. This mat will likely be returned within the next two weeks.
I recently bought this mat to replace an old one that had seen better days in our home desk area! I’ve only had it for two weeks and it’s working well… my desk chair glides easily no indentations doesn’t slip on the carpet. I ordered online and picked up in store. Very easy process. The mat had minimal packaging and was flat not rolled up as others have commented. So far so good. We use the desk area space on a moderate basis. I would recommend this mat.
