The plastic on this mat is very strong and holds my chair with very slight indentations, however, the little gripper teeth are too tiny to get a decent hold on the rug

Clear plastic looks great, and the product works very well with our thick pile carpet.

Feels like hard plastic, not sticky soft rubbery plastic like oldschool chair mats.

Good plastic, but it's only 59 x 47.5 in size.

The plastic is fairly clear, allowing it to blend into the environment easier than other mats

Extremely heavy duty hard plastic that seems pretty indestructible to anything in an office or furniture setting

This one is heavy duty, very hard plastic that accommodates my heavy rolling chair and does not leave marks on the surface.

With the mats I got from those places, the plastic would always deform under the wheels of my chair, leading to small cracks and eventually, large scale failure.

This mat is much better than the typical plastic mats available in the office supply stores.

It's a bit pricey for what amounts to a sheet of tough plastic

The only minor irritation is that it tends to move around on my medium-cut carpet, despite the formidable little plastic spikes that protrude from the bottom

It is far stronger than the cheap plastic mats you can buy at your local office supply stores.

It needs replacement because the cracks are now a hazard ( plastic pops up )

Polycarbonate seems to be a hard plastic that's much more resistant to deforming compared to other, less expensive, plastics

It is a very hard plastic that does not bend when moving around with my chair on thick carpet

lb and the 5 castors on my chair were also upgraded to 3" "rollerblade" type wheels... which probably helps to avoid the pressure points that could cause cracking with standard hard plastic wheels.

Well, it's a plastic

The plastic is strong enough to bear 200 pounds

This is a great very durable plastic covering for an office with plush carpte

It is a very sturdy and strong clear plastic, and no issues with cracking or denting as others have stated (I am also 5'1" and under 115lbs)

why would anyone ever buy a trashy cheap plastic mat when you can have this!!!

They are a very sturdy and heavy plastic of good quality and does not warp under weight.

Compared to the various softer plastic mats readily available at retail, the Ultimate actually delivers on its function.

Well worth its higher price, though not that much higher than what you would pay for the best soft plastic mats at retail.

Great deal and worked out exactly as we needed!

There are no craters from wheels, or cracks as of yet

Works as it is intended.

It will works as it's not cracked to the edges

The chair doesn't sink into this as it is very sturdy.

Still as smooth as when I first put it down eight weeks ago.

The desk chair moves on it almost as well as when on a floor
