Kariev,
I got mine from www.matsmatsmats.com and it's the black aerobics/fitness mat and I love it. I also have tile floors so I put a yoga mat underneath this black mat to keep it from slipping because it will still slide especially when you are doing lateral moves (Heismans, 123s, etc.) without the yoga mat. I forgot whether I have the 1/4" or 3/8", but will check. HTH
jennifer, what size mat did you get?
