Input:
I am a 55 year young woman who was encouraged by my personal trainer to take Pilates to strengthen my core and improve my balance. The mats provided at the gym were meant for Yoga, and while they kept me from slipping on the floor, doing any sort of exercise where we were required to lie on our sides just killed my hip joints.  This thicker mat was a lifesaver. It was thick enough to cushion my hip joints as well as enable me to exercise barefooted, something I had great difficult doing due to massive amounts of foot surgery (don't you just love high heels?). I had read a review that the mat could only be rolled one direction because of the built in straps, thus creating a permanent curl.  This was easily remedied by flipping the mat over when using it, and I had no problem with the mat slipping when being used on the opposite side.  For me, it accomplished exactly what I wanted it to do - protected my bones while I got the exercise I needed.
