Comfortable lying, but odors

It is a relatively small package, so that the first impression is that the wrong size was delivered. Unpacking and find that everything is normal. The mattress topper is very shriveled and one wonders whether this is a mistake, because the left and right missing 20 centimeters. After about 2 hours everything has dissolved into thin air. The mattress has unfolded and there is a lack not centimeters.

The main purpose is fulfilled. Lying is a lot more pleasant than before. The back pain have subsided. The mattress adapts to the body. For this aspect, I give 5 points.

A significant drawback is the smell. The entire mattress stinks strongly of ammonia or the like. Despite winter I had to leave the window open all day.
I immediately washed the reference to reduce the odor.
It will not shake the feeling that this can not be healthy, just because you have to inhale these smells / fumes 8 hours.
Even after days of pungent smell is still there.
All in all, I would not buy the mattress because of the smell again, but would rather spend a little more money to sleep easier can that one has produced no other health problems. Therefore, the product gets only 2 points in the entirety.

PS: after a few weeks the stench is gone. Sleeping comfort is very acceptable.
