BesWinOffice Chair Mat for Carpet, 48'' x 60'' Clear Floor Mat for Low and No Pile Carpeted Floors, Thick and Sturdy Carpet Protector for Work, Home, Gaming, Easy Glide and Flat Without Curling

My husband loves this mat going underneath his chair for the computer and also for his TV tray table works very well. It’s we have a deep carpet and it holds the deep carpet.

Unrolled it and placed 2 dining room chairs on it, 1 on each end. It was flat and ready to go in a couple of hours.

Came rolled in a box . Some what difficult to unroll . Must put a heavy weight on end then roll it a little then put more weight until completely unrolled. It was somewhat flat after 48 hours with the temperature high about 58. The sun came out , then put in the sun . That works the best . After about 6 hours was flat enough to place on floor. it does what I bought it to do . Just be aware it is not open then use . Must be allowed to flatten with heavy weight. Thickness is good .Not rigid .

great fit for my ex's small apartment

I bought it in mid February. It was almost impossible to roll out and lay flat. It was so stiff I had to wrestle it and spread paper boxes full of books at all four corners to keep it flat. After a week I tried to use it but it curled up into a roll almost as tight as when I received it. I had to leave it for a few weeks until it stayed relatively flat. It still tries to curl up on the edges. Now, after only using it for a few weeks I see cracks at the area where the chair's wheels ride as I move in and out from my desk. I'm only 185 lbs and the chair is a good quality office chair with 5 sets of double wheel rollers. I tried reaching the BesWin service website and it doesn't work.

This chair mat is not as firm as my other chair mat. the wheels of the chair get stuck and has indentations. And, the edge curls a little bit and it has been flattened since it arrived two weeks ag

Great mat for under an office chair on carpet; my only issue was getting it unrolled by myself and weighted down to keep it flat. Once that was done it’s great.

This isn't going to be a comment on the performance of this mat as it's been less than a day since I received it, and, according to the enclosed flyer, it may take three days before I can use it. No, this is a comment on the horrible packaging of the mat and the 90 minutes it took for me to open the boxes and unspool the large 48"x60" mat. It's customer abuse. It makes the most complex IKEA assembly look like putting together a child's wooden puzzle.First off, I received a tall, brown, corregated box (7"x12"x58"). It bore no Amazon markings or Amazon tape so I assume the box was from the manufacturer. (I, of course, don't know that for a certainty.) I opened it. Inside was another tall, brown corregated box (5.5"x5.5"x48"). I opened it. Inside was the wound mat, curled up like a small rug or bolt of cloth. I took it out and Immediately tried to unwind it. It didn't open easily so I searched for tape or some other binding holding the mat so firmly wound. Nope. It was just super tightly spooled and not going to be unspooled easily.To be clear, I'm not talking about a soft, pliable sheet. No, as described on the site, this is a hard, 2.2 mm thick, "premium PVC" mat with 3 mm spikes. Irony alert: "The rolled up package is easy to carry," says the Amazon site. "But it is easy to flatten, just add as much weight as possible to the corners and it will flatten." The enclosed flyer adds: "Your mat will gradually regain and retain it's [sic] flat state. The could take up to 72 hours..."I won't describe in detail the improvised process I used to unroll the mat, only to say that it took about 6 inches at a time to unspool it, leveraging two small boxes to wedge against the roll to keep it from reversing and rolling back up while I employed octopus-like contortions to simultaneously position heavy objects on the mat and unroll it while kneeling or standing on the unspooled portion. All while those 3 mm spikes were ripping into me and whatever heavy objects I tried to use. The five-pound sacks of gardener's pebbles were no match to the stiff premium PVC. I wound up securing the four corners with two large tool boxes, a box of photographic equipment supplemented with a bag of coins, and the two-volumn condensed Oxford English Disctionary.So that's how things lie right now. The flyer suggests that the flattening process might be speeded up a bit by placing the weighted-down mat "in a warm room or near a sunny window." Well, it's 13-degrees here as I write this review; the heat's at full blast, and I'm still wearing a thick sweater here at the keyboard. Warm and sunny are relative, I guess, but I don't think I'm going to make a lot of progress on that front. I might, however, give my wife's hair dryer a try.Addendum: It's been two weeks now since I unspooled the mat and 10 days since I placed it. It's lying mostly flat, but about one-third of the total area--not permanently secured by the wieght of the desk and my occupied chair--remains noticeably bowed. The bow on leading (unsecured) edge is one-and-a quarter-inch off the carpet.
