Description

Glass Chair Mat Tabbed Glass Chair Mat Glass Fireplace Screen Glass Desk Pad Casters Will this chair mat crack, warp, or turn yellow over time?

Backed by a Limited Lifetime guarrantee, no warping, no discoloration. Does this mat work on carpet and hardwood floors? Yes — it's designed for all floor types. It works on low, medium, and high-pile carpet (the tabbed lip grips carpet to prevent sliding) as well as all hard surfaces including hardwood, tile, vinyl, and laminate. No tabs are needed on hard floors. Will my office chair roll smoothly on this glass mat? Yes. This mat features patented 1" beveled edges with rounded 3" radius corners so your chair glides on and off smoothly in every direction, no wheel catching, no cupping, no mat shifting. Chair wheels are protected, and the mat stays in place. How much weight can this glass chair mat hold? This mat supports up to 1,000 pounds thanks to its ¼" premium tempered glass construction.

  • 1000% better than vinyl chair mats! The beveled edge works perfectly and is important
Color: Clear (Standard Clear) Size: 45" by 53" Non-Tabbed
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. ... show more

  • Top quality, heavy, crystal clear, chairs roll like they are on ice
Color: Clear (Standard Clear) Size: 36" by 46" Non-Tabbed
Weary of low end plastic mats for my carpeted office, I purchased this tempered glass version. The 3’x4’ size was ideal for my office. My office chair rolls on the glass like it’s on ice. The tempered glass is easy to install once you get it unpacked. It is robustly packed and arrived in perfect condition. It appears very durable, is crystal clear and the sale price made it a must have for me. Even the best cheap plastic mats crack over time on carpet. This mat will not. There is an unmarked brown envelope on the packaging. It contains a series of round clear silicone self adhesive feet. They went flying around the room when I opened the envelope so use care when opening. Even the smallest 3’x4’ chair mat is quite large in the package. It may require 2 people to take a larger one to a second floor. Very happy with product. It looks great, is performs well and I hope it’s the last one I ever buy. ... show more

  • So far- a total winner and happy to protect my LVP flooring!
Color: Clear (Standard Clear) Size: 46" by 46" Non-Tabbed
Like so many people who invest in luxury vinyl plank flooring, I (wrongly) assumed that the planks were impervious to the vagaries of desk chairs rolling over them. A supervisor at Home Depot told me point blank (after purchase) that I need to protect that gorgeous floor! So I started looking at old-school plastic mats, which I realized were not going to stand up to a 230+ lb guy rolling back and forth on a daily basis. I about choked when I started looking at the price point for the glass chair mat here on Amazon, but the reviews were clearly over-the-moon, so I shut my eyes and pulled the order trigger. A few days later, here was a GINORMOUS package waiting for me on my doorstep, and I mean this was BIG and this was HEAVY and this was SUPER WELL-PACKED to protect during shipping! I live alone, and so I made a decision to unbox it outside my front door then carry this bad boy with some trepidation into my home office, and lay it carefully down on the floor. I purposefully shot the photos to get some reflection off a couple of the images to show it is GLASS (tempered, NOT "Safety" glass!) and the one with my tennis shoe is more a top-down (almost) angle to show the flooring beauty). It stays put- it does NOT slide around AT ALL! The glass was immaculate and CLEAN after unboxing, it will be interesting to see how it holds up over time with dust and such, but on day 1, all I can say is BUY IT! I absolutely love how good looking glass is compared to plastic, on a hard surface like LVP, laminate or real wood - I believe this is a totally justified investment to protect your floor! I'm 75 and it's hard to admit that after all these years, I am in chair mat Nirvana! The beveled edges make it simple to bring your chair back onto the glass if you go too far, but the easy solution is buy a BIGGER MAT. I got one that is 42 x 42 inches which is perfect. If I push back away from the desk to stand up, it doesn't roll off the glass at all. It doesn't move around if I don't want it to, but when I do it's like 'on glass' and smooth as silk to maneuver. I am totally enamored with this purchase! ... show more

  • Even better than expected!
Color: Clear (Standard Clear) Size: 46" by 46" Non-Tabbed
I didn’t know how tempered glass on carpet would feel walking and rolling on. But turns out it’s perfectly stable and firm under foot, and the chair rolls so smoothly, yet controllably. For reference, the chair is from the 50’s/60’s and has hard rubber wheels. Yes, as always, be careful when sitting on your rolling chair, but I was relieved when it didn’t feel like I was on an ice rink (!) - actually very easy to do. The mat is beautifully made, and the patented edge bevel is much safer (and more attractive) than non-beveled. Also, I had a question for customer service, and Hiram answered the phone after only a few rings, and took care my question quickly and professionally. He was also a nice guy who appreciates their customers. This purchase was a great experience all the way around. ... show more

  • Definitely worth it if you are willing to spend the money.
Color: Clear (Standard Clear) Size: 36" by 46" Non-Tabbed
Overall good. The surface is quite smooth, but shouldn't be too much of a concern when sitting, but if you like laying back, I recommend adding a rug for some friction. It is heavier than I thought it would be, so I would recommend having 2 people unpack it, but it is still doable for 1 person if you have the tenacity. ... show more

  • Great Computer Chair Mat with Beveled Edges
Color: Clear (Standard Clear) Size: 36" by 46" Non-Tabbed
Great addition to the home office. We just had our carpet replaced, and this mat effectively protects the carpet while making it easy to move around in our new computer chair. The beveled edges are an excellent feature. It looks great too.
