Input: Consider Input: Love the feel of the sheet set but very disappointed in the cooling effect that your website describe. It is not at all cooling when sleeping. In fact tit gets really warm and still waking up sweating. This purchase was completely unsatisfied. I washed it so I have to keep it. I am very disappointed in this product.

Output: negative


Input: Consider Input: So glad I bought this. I use a yoga mat most every day and this has become my favorite. It's not only beautiful, but it's thick, cushiony, and has great grip support for push-ups and yoga poses.


Output: positive
