I'm pissed, have this part used only once, and it's broken. Since I bought this mattress a few weeks ago and was able to try just now I did not even get my money back from the seller. I can only advise everyone of this part to stay away. I have only the mattress located (I weigh 65 Kg), am not sure rumgeklettert or otherwise and after one use, the seams were already broken. Since I had the 25 Euro also may be the same kick out of the window. Am absolutely disappointed even by the seller.
