I like it. What I read on Amazon said lays perfectly FLAT, but it was not flat it was ROLLED UP be CAREFULL when you release the ROLL it's like Releasing a GIANT SPRING MY WIFE and I are happy. We had to use double back tape to hold the corners DOWN so NO ONE CAN TRIP. it's worth the MONEY make sure your floor is clean so the tape will hold.I would describe this material as similar to the panels used in florescent light covers only slightly less brittle. If you were to fold it in half, it wouldn't snap, but it would leave a cloudy line at the seam.My mat came dented in 2 places from being folded too hard during shipping. The box it was shipped in was very flimsy, and denting could have been avoided if they shipped it in a stronger box or if it were shipped flat. Luckily the dents were in inconspicuous enough places that I can live with them.I cut a 10" × .5" notch in mine to accommodate a table leg. I used sturdy scissors but it was pretty difficult, I'm surprised they didn't break and even more surprised that I didn't cut myself because the material is very sharp. I just didn't have a better tool on hand.I actually put this on carpet, although it's intended for hard floors, since it was the only one offered in this material in the large size I needed. It is sturdy enough that it doesn't sink in enough for you to notice or leave marks, and the chair glides easily.If you're putting this on nice, hardwood flooring, I'd absolutely sand down the edges, there's a very slight lip formed on the underside of the edges from the cutting process that would scratch up your floors if there was any movement.It doesn't lie flat-flat, the corners life up very slightly (just a quarter inch), it doesn't cause problems with my set up, but it may for others.Overall very happy with this purchase.I bought several of these mats and while they are pretty great overall, I did have a problem with one of them. Unfortunately, I didn't unbox the last one until well after I could return it for a refund or exchange - the office wasn't finished until recently and I didn't need it right away.The size I ordered, 60" x 48" was packed rolled up in a big box, which makes sense, I suppose (I ordered one size smaller previously and it came shipped flat), but made it unwieldy and hard to store until I needed each one.When I pulled the last one out of the box to install into my newly refurbished office, I could see where the product had been buckled in two places, (probably from trying to wrestle that big thing into the box) much like a photo gets buckled if you try and hold it with one hand, but I thought 'no big deal, it's going on the floor'. The first time I rolled over that buckle with my chair, it crushed the polycarbonate and will soon be a hole. I covered it with packing tape for now, but this one mat is something I wasted over 70 bucks on because I didn't inspect as soon as I got it. I am disappointed.The other mats are just fine and work great on hardwood floors.I thought this product would suffice for pine flooring but it does not.My pine floor is new, and I have a 5-wheeled office chair which, with my weight (175 lbs), will put grooves in the floor when I wheel around. I purchased this product to stop that.The material is about 1/8 inches thick. I thought it would be a little thicker. After putting it on the floor in a new area of the office, sitting in the chair, and simply moving around, I lifted the mat up and saw it definitely lessened the grooving, but still saw impressions. I speculate after a few months my floor would have deep grooves.I'm sure this would be fine for hardwoods as it is only as strong as the floor its on. Given its thickness, it does not have the strength to hold up on its own. Polycarbonate is made to stretch some, that's what gives it unique strength characteristic. For softer wood, a material like plexiglass is probably preferred since it doesn't stretch like polyC.I love the look of it on the floor. It allows the wood to show through with minimal distortion and intrusiveness.The smooth side is supposed to lie on the floor, allowing interaction with the surface creating a static bond. The top is rough to engage the wheels. If you put the smooth side down, the sharp edge will not be felt. I believe some people are putting the smooth side up which puts the sharp edge on top allowing it to be felt if you hit it, and thus risk getting cut.I'm debating whether or not to send it back because for my floor, it doesn't provide the protection I require. However for harder woods, this should would out perfectly.I just bought the 48 in x 60 in chair mat. While it is sheer, but not clear, the wood can be seen through it, and was a lot cheaper than a glass. It came loosely rolled up, but flattened out immediately. Mat seems hard and durable. So far it is working perfectly, looks good, and I am very happy about this purchase. I would highly recommend.The 47 x 35 was shipped flat and the edges did not curl up. I was happy about that so I ordered the 48 x 60 and was disappointed to find that size product was shipped rolled up in a box. It would not lie flat, even after putting a raiser underneath and weighing down the edges with heavy books for 2 days. However, this helped (not 100% so far, but much better): I rolled it in the opposite direction than the way it was shipped and put it back in the box (not so easy to do unless you have some help), strapped it in with velcro straps in rolled form (this step probably not essential) and left it there for two days. The edges are only slightly raised now and more functional. Note to seller: please try to find a way to ship it flat, even if you charge an extra surcharge for that. Thanks for a good product, however!Für meinen Geschmack dürfte die Floortex Bodenmatte gerne noch deutlich dicker sein. Aber gemessen am Preis kann man eben keine Wunder erwarten.Nachdem meine letzte Bodenschutzmatte (aus PP) krumm wie eine Banane war und an allen Seiten 10-25cm hoch ragte, ist die Floortex Polycarbonat Matte ein echter Lichtblich. Die Matte lag nach dem Lösen des Spanngurts sofort perfekt flach auf dem Boden, wie man das von einer Bodenschutzmatte eigentlich auch erwartet. Wie haltbar die Matte bei Belastung durch einen Bürostuhl ist, wird erst die Zukunft zeigen.Angesichts des Preises und der Planheit der Matte ist sie für mich aber eine klare Kaufempfehlung und den billigeren Matten aus PP haushoch überleben.I have no issues with this mat. Its a hard plastic, unlike my previous mat which was also for hard floors but was rubbery. Because this one is hard, it doesn't migrate around like my previous mat. I love the large size, it fits my work area perfectly and I don't roll of the edge. After about two weeks it has a slight downward curl on the one end, but its only up 1 or 2mm, so no issues. My other mat didn't lay flat either after 11 months. I'm going to park my chair on the end at night and see if it fully flattens. I could also rotate the mat 180 degrees so the curl is under my desk and it would be completely unnoticed. Long story short, I would recommend and would purchase again. My only regret is not buying this in the first place.My Cleartex Ultimat Chair Mat was shipped flat, so installation was simply placing it on my office hardwood floor with the clear, flat side down. I also order the bigger size 48" x 60" and I'm glad I did so I can move around a bit more on my chair. Quality is excellent for this premium clear polycarbonate mat, although it's not clear like glass. I'm pleased with this purchase, and expect this mat will last for a long time. Thanks.Who would have thought that a hard floor mat would require so much research? And I do appreciate ALL the information Floortex gave when helping with the decision of a high traffic, hard floor mat.Item sprung open ( as per warning ) when last tie was cut and sits mostly flat.As well, item was delivered the very next day! Inside of a twenty-four hour turnaround!I like the fact this is a high quality floor mat for hard floors. I use it on hardwood. I am disappointed with it because contrary to what the company says, the mat came rolled up and despite the fact it sprung straight when unwrapped, it did not lie completely flat on one end. The other thing about this is the dimensions were not as advertised. It said it was 48 inches by 60 inches and the actual size is 47 inches by 59 inches. Not a big deal but not what was advertised. I reordered it to see if the first one I got was an anomaly but the second one was the same size and actually worse at lying flat. I followed the instructions and gave it over 72 hours on a heated floor to straighten out but still did not faltten out. I returned the second one and kept the first one as I needed something and this was better than other products I tried from other stores. This was expensive for a sheet of plastic at $149USD. I would have returned it had I gotten the advise I did later that to solve the problem of protecting hardwood floors, all you need to do is buy roller blade type wheels with rubber around the wheels and replace the chair wheels and bingo you'e done. Cheaper too at less than $40 bucks. I got the wheels for other chairs in other rooms so in the long run I save money.
