Exclusive Beveled Edge Glass Chair Mat for a Smooth Glide and Easy Roll On/Off by Clearly Innovative, Ultimate Office Chair Mat for Carpet or Hardwood Floor, 48×52 Tabbed

1000% better than vinyl chair mats! The beveled edge works perfectly and is important
I can’t express enough how happy I am with this new glass chair mat vs. a previous *thick* vinyl chair mat of the exact same size this glass mat replaced! Like night and day having a rigid surface to walk and roll the chair on, vs. the vinyl which continuously deforms. The room is carpeted. That previous mat was pretty much the best and most expensive vinyl mat out there when I bought it, 1/8 inch thick with rug grippers. Even so after several years the middle section had lots of cracks and chunks were even falling out. It wasn’t until I used this glass mat that I realized even when new that vinyl mat was deforming a bit under the chair wheels, making it harder to roll around.I’m leaving the 5-star review even though, as many have noted, the outer box packaging is inadequate. Showed up with big sections torn out since it is only a single-wall box for something this heavy. The UPS driver had even left a mea culpa note saying he had written in their notes the box was shredded. BUT… the god news… the inner packaging around the glass mat is as good as the outer packaging is bad. That saved it. Heavy press-board rails with a thick rubber strip around all 4 glass edges. Then thick heavy foam material over both glass faces. The inner packaging came through just fine. I have a theory. In China the mat and the inner packaging are probably one company, the manufacturer, but then that goes to another company to add the outer box for transport. Company #2 dropped the ball, apparently. Long story short, don’t let the bad packaging on the outside stop you from purchasing, but do take photos when it arrives in case something has happened to the inner packaging.A note about the beveled edges. I was having the hardest time deciding between buying this glass mat and another similar one on Amazon without beveled edges, but was less money. In the end I decided that since I walk around with bare feet , having a non-beveled edge would be uncomfortable. I can see I was exactly right. 🙂 I’m sure the edge on the other glass mat is rounded and not a danger in terms of cutting a foot, but still it is a 1/4 inch bump to walk on that this mat doesn’t have. This one sinks into the carpet enough that I don’t even feel that edge with bare feet.As far as sturdiness goes, I’m a large guy and I even have two table legs on the mat (although using the kind of coasters with carpet on the bottom, so as not to scratch). Works great. If this glass mat hasn’t broken with me it probably won’t with you, either. 🙂 I’m using the typical 5 leg office chair, but long ago I replaced the standard hard plastic wheels with the rubber tipped kind rated for 350 lbs dynamic load each (3 inch wheels, from Amazon here). The plastic 2 inch wheels would always eventually break on me until years ago I started replacing them with the higher-weight-rated wheels. Added benefit of the rubber on them.In summary, every single time I walk on this hard-surface glass mat or easily roll my chair around in it I just smile, comparing it to the vinyl mat that this one replaced. So much better. Worth every penny of the cost.
