Review on Premium Non-Slip Yoga Mat With Carrying Strap And Bag - 72"L X 32"W, Ideal For Exercise And Fitness At Home - Gruper Thick Workout Mat by Justin Wehrman

I have had this mat for a year. It has never stayed in place (i have even tried flipping it over. No luck). I have to put 40 lb weights on the corners to keep it in place. It stretches when you apply pressure; so down dog, mountain climbers and any sort of lateral jumping are all incredibly unstable. I don't usually use shoes while exercising, but the few times I have worn shoes they have left some serious gouges in the foam. It is however very thick and comfortable, so if you are planning to use it for light stretching activities it might work.
