It was unexpectedly heavy when I got to lift it. But it's very solid I needed help to unravel it in the correct way. But it does the job, my new carpet is protected and I can use my office chair much easier. Great purchase! So far so good!

This is the most comfortable desk chair I’ve ever owned. The lumbar support is incredible. The arms lift up and down and they can go sideways. Easy to fit under a desktop very comfortable and very sturdy. I’m 6’1 395. The strongest chair I’ve ever seen looks amazing. 

I use the mat in my home office. It’s the perfect size for the space. It is sturdy and doesn’t curl. It shifts slightly over the course of a week or so. But I attribute that to the thickness of my carpet. I would probably look for a mat with deeper studs on the back if I had to purchase again. That might be something to consider when purchasing.

As a rule I don't do reviews but this mat was so exceptionally bad I had to warn potential buyers on this one. One star only because I can't give it no stars. It arrived July 9th. Within only 2 weeks of normal office use (I weigh about 180 lbs) 2 very visible cracks appeared. It is now Sept 16 and now there are about 11 cracks average 6"-7" wide. The photo doesn't ven cover all the cracks after a couple of months. Even if I was offered a brand new one I wouldn't take it. No more polycarbinate stuff. Going back to my vinyl. This was flat out awful.

Fantastic mat for the thickness of the polycarbonate and the price. Will update if anything changes.
