qqThese mats are actually more comfortable than I thought. I had trouble with my previous kitchen mats due to them constantly shifting around and the corners curling up causing me to trip from time to time. But these mats wont give me that problem because they seem to hug the floor and stay there. 
The comfort is great as well. I was working in the kitchen most of the day and I didnt have any pain shooting through my heels nor trying to take sit down breaks. Im back to enjoying being in the kitchen again. Get you a set if you want to get rid of the kitchen fatigue.
