+200 lb guy siting on a wheeled chair makes the wheels sink in a little bit and hard to start moving but once I am going it rolls fine. I think if it were a little thicker it would help stand up. Also was very dirty when I got it delivered. I had to clean it 2-3 times before the papertowel came back clean. Forget trying to clean the bottom spikes make that impossible. Maybe with a hose outside but its winter now... dirt was mostly dust and grit. Looked like someone had dragged it through a dessert before puting it on the truck. icecream and chocolate sauce everywhere.
I bought this because of the hardwood floors in my office. It doesn't have a beveled edge like one we bought before from Staples so visually it's not as nice and I guess there would be a bit of a drop-off if the chair were to roll off the mat. It works fine though. I was worried about how it would arrive since we had to have it shipped. It came folded in the box on a cold day. We left it warm up before slowly bringing it the flat state. I was surprised that it did go flat and shows no bumps or other issues.
