Marvelux 47" x 53" Heavy Duty Polycarbonate Office Chair Mat with Lip for Carpets | Transparent Carpet Protector for Low, Standard and Medium Pile Carpeted Floors | Multiple Sizes

I was worried reading so many reviews stating their mat cracked, chair couldn't roll easily or had large dents from wheels. This did come rolled and had a warning to unpack very carefully due to it's being rolled under pressure. Unpacking was challenging and it did go flat immediately once released from it's binding. It was also challenging to place this very unflexible mat into the tight corner my desk is in, but I did manage it and since then I'm loving it. It is solid, no denting and my chair rolls easily. I have a large chair and I'm a hefty woman, so that is all a huge plus. I think the most important element to success with this mat is to be sure you purchase one for the correct depth of carpet. The spikes on the back of this mat seem to be the exactly right depth for my carpet to reach the flat subfloor and maintain a nice flat mat. Carefully measure your carpet depth and order the right mat and all will be right with your world!

Really wanted to like this mat, especially since it was firmer than usual soft mats you buy. I thought paying more would result in a mat that was thicker and would last a lot longer, unfortunately this was not the case. The mat cracked on both sides where the lip connects to the main body after a few months.Attempting to use duck tape on both sides to hold it together seemed to just make it worse over time, eventually tape got embedded in carpet, likely ruining that section of it. I don't believe this mat is worth the high cost given how quickly it fails.

Be careful opening it up since it will unroll like a tight wound spring and you can get hurt.!!!!Besides that, it instantly laid down flat, my chair is rolling freely and it is thick enough not to get indentations from the wheels like cheap maps get. Overall, highly recommended and I will replace the rest of the mats in office and working area with those.

This has been almost 8 months and it has broken however warranty on it got me another one but I don't think I'd buy another one after this one cuz they don't last very long not too happy with it

This mat works well on very low pile carpet. It is made from a crisp but somewhat flexible plastic (not rubbery). I ordered a different mat last week and had a horrible experience trying to unroll it - far too rubbery/firm and immediately got wheel-stopping divots.) This mat shipped flat, unlike so many other brands that are shipping rolled up. Thank you!The mat can be scored and snapped (if you know how to score and snap plexi you can custom cut this if you need to), but you will have to file/sand and torch the edges if you want to regain a smooth edge.I purchased the two pack version of this product "with lip", which I did not understand at the time. "With lip" simply means that there is an extra tab or notched out lip of plastic on one side of the mat, intended to go underneath you desk/seating area. It's fairly useless.Also note that the lip area is on the shortest edge of the mat, so the orientation of this mat is predetermined to be portrait/narrow instead of landscape/wide.I'm happy to have two mats "with lip" for nearly the same price as any other mat for sale on Amazon. If this first one fails, I'll use the second one until it fails. :D

Crack happened within 3 months of ownership. Bummed, no warranty beyond 30 days.

I've used this mat for months and it hasn't dented, gotten groves, cracked, yellowed or even shifted out of place. It still looks brand new! If you need a heavy duty, transparent, full size office chair mat that actually supports weight and will see a lot of daily use- this is the one. It's well worth the price. I put the second one under my craft room work bench. If I drop a tiny project component, I can easily spot it on the mat!

Help up for 3 months and then began to crack all over. Terrible product and would not recommend
