I’m really impressed with this tempered glass office chair mat. It looks sleek, feels very high quality, and it’s been super durable under my chair on carpet. It doesn’t flex, crack, or slide around like the cheaper plastic mats I’ve used in the past. Now for the unexpected “durability test”… The delivery company decided to place the box directly on my driveway in front of my garage door (bold choice). Then it snowed. My wife didn’t see it and drove right over the box with her Honda. I fully expected to open it up and find a million pieces of glass. Nope. Not even a crack. So if you’re looking for a chair mat that can handle daily office use and survive being run over like it’s training for the Olympics, this is the one. Highly recommend! Read more

Discovered box. It was a little chewed up in places. Glass inside showed no flaws. Looks great but I bought it for functionality (fly tying station/craft table under construction). I'm a senior of average build. I was able to pick it up and carry it by myself 6' tall. Shorter folks may have trouble moving it solo unless they're in shape. I did open it on carpet and could glide it to location. For moving it across hard surfaces I definitely recommend two people. It's only 65lbs I think. But it's awkward to move. I almost discarded the pads until the little packet fell out out box. You definitely need room to unbox it. Looks and feels high quality. Time will tell on durability but I wouldn't hesitate to get another. Large size 65 X 50. Nice rounded corners and a slight bevel all around. Read more

I’m not docking stars for my own back pain. That to me isn’t ethical. The quality of this is excellent, it doesn’t slide on the floor, very scratch resistant and overall is a good value for what you pay. However, if you have back pain, this will cause more pain because your body will have to adjust to the very hard surface. Do not get it if you have back pain. If not, 100% great buy Read more

I've used several plastic chair mats and they don't look good nor hold up. Decided to spend the extra bucks and buy this tempered glass chair mat. It is the BEST! Smooth, non-marking, and just looks good. Highly recommend. Read more

It was well-packaged, and I will save the packaging for an upcoming relocation. I use this over a dense, but not thick, carpet, and it stays in place. It is thin, but heavy, very clear, and barely noticeable. The corners are rounded but the edges are not beveled. The lack of a bevel is not an issue because my workspace is compact and the mat is large enough to preclude the need to roll over the edge. My chair rolls very smoothly over the surface. Not inexpensive, but worth the money. Read more

I purchased Koonmi glass chair mat a few weeks ago. It has worked well, my chair slides rolls easily on it, and the glass is of quality that it hasn’t shown scratches. The only slight disappointment is that the mat slides over time and I keep moving it back an inch out so. It is on a plush carpet. Read more

Delivered in flawless condition. The box was a bit mangled, but it didn't impact the glass inside. Glass looks great, perfect size for my need, and is holding up strong. I have about 500 lbs on it at all times and upwards of 800 lbs on it and it hasn't had any problems with the weight. It does slide a little bit over time, but it's easy enough to reposition and hasn't really been an issue. It has completely fixed my problem with trying to roll on carpet and I couldn't be happier.
