Smaller one cracked after 3 months, got this new thicker/bigger one and its working well 3 months in.

Others are ineffective for chair movement and have cracked soon after purchase.

After a few months, they all developed cracks and ultimately broke through in the worst contact areas.

Like a lot of people, I'm sick of chair mats that crack.

I did a lot of research before replacing my cracked and broken 9-year old chair mat

This was rated for 1/2 inch plush but was used on commercial grade carpet, still failed (cracked)

no dents from wheels and no cracks

Lasted 5 years in a lightly used (2 to 3 hours per day) home-office environment on a low pile carpet (in front of computer) - then developed significant cracks

Has broken/cracked on me multiple times

Durable, sturdy, no cracks or issues; very easy to clean.

It still looks brand new, no areas where there is cracking or where the chair is sinking into the mat

With enough of fractures lining up, it can create a larger crack and even break.

Like a lot of people, I'm sick of chair mats that crack.

Its sturdy, so far it has not cracked anything.

Over time, this crack has worsened and is now large and unacceptable.

Amazon was kind enough to replace the cracked original( the manufacturer pretended to allow returns but really just makes the customer jump through multiple hoops even though I sent them clear photos of the cracking - their policy seems to be: assume the customer is lying ) but now, approximately 18 months later, the replacement is starting to crack ( I weigh 190 lbs, so it isn't me causing a problem ).

No dents from my chair, no cracks, no scratches.

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
