The chemical smell is just too much to bear and I got a bad headache after a few minutes. And, although both mattresses were aired two weeks each in the garden house with plenty of fresh air.
5 stars there but for Amazon, which could pick up again without discussion both mattresses. The service staff of the Hotline were both super friendly and had understand that I could not use the mattress due to chemical stench.
Of course I also draugelegt me to test times ... the hardness would have already agreed, but the smell was unbearable.
