Mammoth Corner Desk/L-Desk PVC Plastic Chair Mat for Medium Pile Carpeting, 48x60 Inches (V4660TMP)

This mat does everything we wanted it to do, owing to intelligent design with a dose of simple good sense. The material is an extra-thick polycarbonate that can take the weight of normal use with out developing creases or unsightly "drag" marks. It's also textured for extra sureness of grip, but also easy to keep clean. The bottom is cleated with just the right sized little points that grip the carpet without ripping the pile. We were afraid the mat might be too fragile to last for than a year or two, but of course, all such fears were put to rest when it arrived.Best of all, it flairs a bit, allowing the smaller end to be placed under the desk while providing sufficient protection of the rug below. It's one of those common sense things that, oddly enough, is hard to find amongst similar Amazon listings for the same product. We were putting this over a custom-designed rug that cost us more than we would care to admit, so having the right amount of coverage while also having exposure of the carpet's design was a goal this product met quite nicely. Unlike other "T" shaped mats, this one is sparing enough to allow the underlying floor to be appreciated rather than obscured, a difference that changes the look of the whole office.My packaging review for this purchase (not usually available to the public) takes Amazon LLC to task for actually forcing this material into a rolled cylinder that resulted in what may be a permanent misshaping of the product. However, we have found that hitting stubborn areas with a blow dryer helps relax the vinyl a bit, but it's slow-going. That's not the manufacturer's fault.I'm pleased to recommend this product and manufacturer. Great job!

Yea folding it can be rough, but as with any plastic a little heat and time will flatten it out. I got it flat after about a week and a space heater. In the summer any sunny place can do (garage mentioned in another review. However, the quality isn't very good. I'm average height and build, and after three months on 1/4" carpet, it's already cracked in several places. Normal wear and tear, no office Olympics. Too bad, I like the shape. I'll be looking for a thicker mat, or one made with more durable material soon.

I couldn't find the measurements of the narrow end so it was wider than I wanted but I attempted to use it anyway. I used this at a desk where I did not roll straight in and out so mat tended to slide to one side and ride up the desk. The carpet was a tight nap so maybe the pile needed to be longer. In any event it cracked after 3 weeks of use so I moved it to another area with less use and not a corner unit. It is holding up but does not receive daily use. I would not purchase this for a corner desk but it might be fine for a straight desk.

This thing is way too thin to work on non-office building type carpet. It constantly shifts around, I've never been able to make it to lie flat, despite trying all of the techniques discussed in other reviews. It's useless to me.

They shipped the mat folded accordion style! Would not even try to flatten out. Sent it back. $89.00 for a mat that turns out to be a "roller coaster" is a joke. Stay away from this product!

I have L-shape desk with my printer cart off to the side....this large mat allows me to slide over to retrieve copies. Stays flat on my med pile carpet.

It was folded and placed in a small box such that it will never be without unevenness!

I returned. Weird size. Odd size is posted, but, key wrord isTRAPEZOID!
