Cautiously optimistic!  When I read some of the reviews I had mixed emotions about the product.  I liked the fact that it has different certifications.  I liked the fact that someone reported no off-gassing which I can confirm.  I was worried because some people reported they received the wrong size.  But I received the right one and I am over-the-moon happy with it.  Perfect size, firmness and quality.  Definitely recommend!
