So I already had an office chair mat that technically did the job, but I really didn't like how it indented when you stopped moving, which would make it hard to reposition myself due to my chair being sunk into the mat. So when this mat went on sale, I thought I would just try it out and see if it was an improvement over my current one.The mat came packaged in a box and rolled up. Just like the other reviews say, the unboxing process does need some care due to the mat having a lot of tension when you remove the packaging. I did notice that the edges were pretty raw and looks like they were just cut from a roll, but definitely not so sharp that I needed to be careful. My older mat definitely had a nicer machined edge than this one.When I placed this one down next to my original mat, I was immediately skeptical because touching it, I could already tell that this new one was slightly thinner and more flexible in my hand. Regardless, I still switched it out for a proper test drive. I pulled my chair back on it, sat down, waited a moment, and then repositioned myself... and I rolled perfectly smooth without any indentation resistance! I was pleasantly surprised to see that even though this material is technically thinner, I think it has more rigidness to resist chair wheels sinking in.Visually, the mat has a "crystallized" texture that makes it shimmer, but still maintains a clear transparency without being foggy or frosted. The back side has knobs that hold the mat against carpet. I did see reviews that complained about cracking so I will keep an eye out for durability and update this review if I have any issues. So far, I am extremely happy because I've tried a couple mats and this was undoubtedly the best option considering price, quality, and performance. So far, so good!
