When you receive the package, the item is vacuumed sealed, so you will be surprised that when you unfold it there are markings at the center. But then it will be gone as soon as it expands to its original form. I am satisfied with the material, it is very soft, I can stay on my bed the entire day. I can't actually notice anymore my awful mattress from below which gives a backpain and for the reason why I bought this item. The only thing that I dislike about it, is the smell, smells chemical, its not the kind of smell of new clothes or any fabric but instead it smells chemical. I hope it will be gone after some days. Its been 2 days already since Im using it, and I can still smell it. I have sprayed perfume already in my bed, and I have two layers of bedsheet but the smell still lingers. Other than that, I am happy with my new topper. Im thinking of buying a new pillow.
