I adore this mat! It does have a rubber smell when you first start using it, but I didn't find it over powering. The smell does go away after the first week of use, I promise. I use this mat five days a week.Please don't leave in the sun it will crumble for it is real rubber. To clean you can put it in the tub and air dry, but I would roll in a towel as well to get all the water out.You will get a lot out of this mat, and I would proudly recommed it to a friend!
