It's too soft. my chair doesn't roll smoothly. While in your store your whole mat inventory was in a pile on the floor in no order. With no employee in sight I had to dig through the pile to find the right one which turned out to be the wrong one.
I wouldn't buy this again. It constantly moves since the spikes on bottom are so small. My chair wheels dent the vinyl and create grooves so it's difficult to move the chair.
