Floortex ECM121345ER Cleartex MegaMat Heavy-Duty Polycarbonate Mat for Hard Floor/All Carpet 46 x 53

Quality-wise, this is great. Thick and holds up both my desk, chair and myself. Chair now rolls around fabulously showing how garbage my previous chair mat was. This is a solid alternative to tempered glass ones. I had thought about those but found limited info whether it can support both desk and chair on uneven carpet. Reviews said this still slides but I used some extra futon grip pads I had. The mat has not budged one bit and since I'm not in the running for prettiest office so this works out perfect. Like what others said, the packaging leaves much to be desired. It's just two cardboard piece stapled along the edges. Not a deal breaker since the mat looks like it can withstand rain and animal chewing.

I have had many different chair mats and this one doesn't sink in my low pile rug. This mat is thick and sturdy for hard floors and most carpets. It has a 500lb weight rating, but if you are near that limit, I would not use this on thick carpet, because it will not meet expectations. I can feel it slightly flex as I walk on it at around 250lbs on a low pile rug with a rug pad. The flex is not there when I am in my chair and the chair rolls with little effort, even after being stationary for a period of time. This pad has no grips for carpet and will walk. There is a slight lip around the mat to prevent stubbing or cutting toes and doesn't curl when the chair rolls near it. I have it slightly under my desk to stop the walk and it doesn't warp under that weight. Will update on any issues, if they occur, but I don't see that happening anytime soon. This is worth the price and isn't as scary as a glass mat. This is not rolled and will arrive in a flat box.

Very sturdy! no cracks no breaks ..it does slide around a little but other than that is nice. I am a 230-40lb male and it is holding up quite well.

Seems really sturdy for use under a large person but slides all over carpet. It's just thin office carpet that might as well be an ice rink. So here I am shopping for something to keep the blasted thing in place. If it didn't slide, it would be 5 stars.

I LOVE THIS MAT! I have used a lower quality vinyl mat for so many years that allowed my wheels to sink. Rolling my chair was always a chore. Now my chair makes no indentation whatsoever, and it glides with no effort! I've only had it since yesterday, but so far I haven't noticed any movement. It's laid over medium pile carpet.I chose the MegaMat over the Ultimat because some of those reviews mentioned slight indentations and cracking after a few years. I work at home and use it 8+ hours/day, and I want this thing to last as long as possible.10/17/2017 - A year and a half later, my mat's still in great condition. It does move a little, which isn't surprising considering it doesn't have any spikes. It's easy enough to move back into place. It's still the best chair mat I've ever owned.

If you are tired of replacing your desk chair floor mat every 1-2 years because of cracking, this is the mat for you. Yes, it is expensive, but when you consider the durability and expected lifetime of this item, it will pay for itself over the years. This is a rigid, hard and thick plastic that does not bend. It is shipped in a large, flat package which is a good sign (if they cannot bend it for cheaper shipping, then it's the real deal). I've had this mat for about 2 months now and am very satisfied with the quality. The edges are beveled to allow for easy on/off of chair casters and the surface has a very slight 'bumpy' pattern (doesn't affect movement at all) to provide a little grip so you're not sliding all over the place. I expect this will be the last desk floor chair mat I will ever need to buy.

Sturdier and thicker chair mat than even other Cleartex mats. I had their standard chair mat on my carpet, and it would crack after a year or so. I've only had this for a month or so, but it's definitely much sturdier. It's 2 inches smaller, so I wish the size was the full 48x60. The lip around the edge keeps me from catching the edge with sock or the vacuum. There was a black fleck inside the mat, so I can't wash it off. Annoying, but I had issues with their shipping that I decided to keep the mat despite the spec. The "box" that it's shipped in is just two pieces of cardboard and then stapled/taped around the edge. The mat is heavy and just cut through the staples. First one was dented on the edges because I'm sure it fell out a few times. The edges were sharp around the dents, so I had to return. Second shipped in same inadequate "box", but it did survive well enough. Overall a good mat if you can get it shipped safely.

I have been through several chair mats over the years. They end up with cracks, divots, etc. and I have to replace. This one is the Cadillac of chair mats! No dips when you are rolling over it and it is very thick so I can't imagine it cracking. I feel like this will last a very long time and I am so happy with my purchase!
