As soon as I received this mat I could tell it was a high-quality item. I unrolled it to let it air out because it was a bit smelly (as are most new yoga/pilates mats). Fortunately, however, the odour dissipated within hours. I'm using this mat on my hardwood floors. I like the extra length, but I really appreciate the extra thickness of this mat! I'm pleased -- it's a great quality mat for a great price.
