The product itself is very good ... one of the air mattresses of this type has held for 15 years with me. I always had joy in it. But this new one has very strong ausgedünstet biting odors. But it may be that I'm just become just more sensitive. Even on my attic the smell was still very corrosive. On something like this, I can not sleep! The price-performance ratio is very good. I also do not know if the smell would have given. Unfortunately I needed quickly a new mattress!
