Floortex1115015023ER Floor Protection Chairmat, XXL, 60-Inch x60-Inch , Clear

Despite advertising claims to the contrary, vinyl chair mats -- even "heavy duty" ones" -- always seem to end up cracking, so I decided that this polycarbonate alternative might be worth a try despite its relatively high cost. Yes, it does creep around just a bit, but I can live with that as long as it doesn't crack, and in that respect this mat has performed as I hoped. But four months isn't long enough for a thorough evaluation. Time will tell more, and I will update this review if any problems surface in the future.UPDATE, September 8, 2012: A little more than a year has passed, and I have not yet had any problems with cracking.UPDATE, October 26, 2014: Still no cracks.UPDATE, August 8, 2016: Still no cracks.UPDATE, April 4, 2021: Cracks and a small hole. But that's after ten years! Paid $30 for a warranty replacement. Will update again after it has had time to prove itself.

I bought this mat for very high-pile carpet, then ended up using it on very low-pile carpet. It's only been a couple of weeks, but so far I'm extremely happy with it. My chair's casters slide on it super easily, and it feels as durable as permanent vinyl flooring. I'm glad I invested in an extra-large size, because it allows me to rearrange my workspace without worrying about floor coverage. I use this all day, almost every day, and will absolutely update this review if or when it shows signs of failure.Updated 1 year after purchase:I'm very disappointed; after about 8 months, the mat started to crack in a heavily used section. Now, a little over a year later, there are numerous cracks and an area about a food in diameter where large ragged shards of plastic are sticking up, catching not only the chair rollers but also my stocking feet - OUCH! I'm going to try a trick I heard about, attaching self-stick vinyl tiles over the entire mat surface, but obviously that was not the intention when I bought the mat.

I purchased one of these mats in January 2015. It has survived 2 moves and full-time office use. Chairs roll smoothly over it. Love it.It was delivered to me packed flat between two pieces of cardboard and the fufiller was Amazon. This is a key bit of information.Fast forward to November 2016. I needed another mat, so I searched my order history and ordered another one. I didn't realize this was coming from a different sell even though I ordered from the same product page that I used before. This one showed up rolled up in a small cardboard box. The creases haven't come out. Using a chair on it for less than 5 minutes created a dent. Can't roll on it because the plastic is too flexible and sinks into the carpet. It's on the same carpet as the other one that has no problems. I do not have two identical products despite what was advertised.Comparing the two, the good version will stay rigid if you pick it up off the ground. The bad version will flop. The good version is too thick to roll up and fit into a 5" box.Bottom line: if you get the version that I've had for almost 2 years, it's a great product. If you get the rolled up in a box flimsy version that was just delivered to me, it takes less than 5 minutes to realize what a poor quality product it is.I'm hoping that the problem is the fulfiller sending a knockoff and not that the company has started to manufacture products that are not up to the same quality as they were last year.

I really hesitated to make this purchase...[...](with free shipping at Amazon) for a mat sounded like a lot of money so I used Google and could not find the same mat for less money elsewhere. I have no regrets making the purchase. The mat looks great, stays in position, allows my chair to both move and stay where I want, has not cracked or broken.The details:The mat arrived flat and in excellent condition between sheets of cardboard.The mat is laid on a Berber carpet with no padding between the carpet and floor. The carpet is firm and does not collapse when being walked on.The chair used on the mat has 5 individual rollers spaced evenly from one another. Each of the 5 rollers are about 1 ½ inches wide. I weight about 200 pounds. The mat flexes very slightly under the wheels of the chair. The textured surface and amount of flexing allows the chair to move around easily when I want the chair to move... and keeps the chair from rolling around when I want the chair to remain still. (There are no ball bearings in the wheels of my chair...each wheel is on a shaft).The material of the mat is clear without any tinting and would be transparent except for the rough texture on the upper side which causes a slight diffusing of light. Although it is obvious there is a mat on the floor, the mat and carpet under the mat blends very well with the rest of the carpet in the room.On the bottom, the mat is smooth with numerous individual "spikes" that cover the entire bottom and are located about 1 ¼ inch from one another. The lengths of the spikes are about 1/8 inch. The mat holds firmly in place and does not "float"... the mat is in the same location now as when I first laid it on the carpet. The edge of the mat lays down flat and I do not see any tripping hazard.I hope you will find this review helpful.
