36" x 48" with 12" x 20" Lip (High-Pile)

Really like the mat for my carpeted office. My desk chair does still sink into the mat a little bit, but it is way better than what I had.

This is a thick and, theoretically, sturdy mat. Unfortunately, despite the website stating that this model is good for high pile carpet and a hefty sitter, I have been fighting wheel divots from the very beginning. Given the price point, I admit to being kind of disappointed. There wasn’t a specific weight rating anywhere I could find in the website and that gave me pause. I should have gone with that instinct. I am over 250 and It would be really great if the fact that this mat can’t hold up to that weight on really fluffy carpet was made clear on the specs.

I was very skeptical about purchasing this product for the cost after buying 2 other mats online from different sources that never held up. However, I immediately could tell that this blew both the other mats out of the water. It has held up great so far and worked really really well on my high-pile carpet.
The fact that this was a local (to me) company made it that much better.
One recommendation would be to have the spikes on the bottom a bit longer, as my mat moves a bit over time and I have to readjust occasionally.
