We can not say anything negative about the mattress. I was a bit skeptical of the price due to some previous review, but they arrived on time (as always with Amazon), unpack it smelled absolutely not unpleasant and remained that way. Since I was pleasantly surprised ....
After a day of "development" was placed in a cot, and I, I have also once put it. I think I (nearly 80 kg) could rumkriegen well with the pad a night ... Our child is in any case so very happy.
