Entäuschende Quality & Service

I bought this mattress because it is greatly reduced (permanently) and according to the description should have a pretty good quality.
I am also the many positive recessions have also affected purchase. (Where do these come I seriously)

The mattress had after 2 months already first dents where I was thinking but not yet in.
After a total of 4 months, I was permanently only on my bed base and now have extreme back pain.
German quality and Orthopedic mattress I doubt very much here!

The Customer has first return sent me a standard mail and wanted photos of my slatted.
I also see in the end that my a slatted frame is apparently unsuitable for such a mattress, but my slatted frame is a perfectly ordinary slats. Of course, this mattress will eventually be worn more quickly, but not after 2 months?
I weigh 90kg and have ordered a mattress for 110kg, how is that please be normal after 2 months of benefits saggy?

Dibapur? Once and never again! The money I could have the same fire.
