I bought one of these travel mats before a trip, and love it. I worked well as all the places I stayed were carpeted, and this mat works well on carpet -the sticky side stays in place fairly well, and the softer side is nice against your skin, but still not slippery. I liked it so much then I now use it at home and in class on top of my standard mat -it gives me an extra little layer of cushion, and feels so much nicer than that sticky mat feel. It absorbs perspiration and can be thrown in the washing machine on delicate if it becomes dirty. The other reviewer mentioned that it did not stay in place well, and it doesn't stay as well as a traditional mat, but I have very little trouble with it moving, and I do not find that my feet slip, and a little movement is a small price to pay for having a mat so portable. With all the restrictions on airline luggage, a regular mat would sure take up a lot more room!!
