I put her to the mat to home to do a little yoga and Pilates. We have very cold floor, whatever kept me from above. But the mat is perfect. She arrived after only 2 days, the refrig holds and is super soft. It adapts to the curves, but not a bulge but the bumps disappear after less than 10 minutes. You can of course roll up again and has quasi something ausgedünstet only the first 5 minutes, but the smell disappeared after about a quarter of an hour. It is one of the cheapest mats that I have found and no matter how satisfactory, so 5 stars! Would she recommend to camp as a sleeping mat!
