Well for quality:
Really solid metal frame, it should be noted that the bed should have a center support (160x200). The slats make a stable price for the impression. The tip of another buyer here to glue the frame with Filznoppen was really great. That part makes anyway no noise.
And the result:
We are finally comfortable and stable, wake up with back pain in a hollow without morning. In my old, saggy slatted frame with slats 160er without midsection last no longer beautiful. Is also pleasant that the respective side at waist level can be set separately in the hardness again.
Anyway, for the price an absolute buy recommendation! Even if the rust is worn out in a year, I have it only 80, - paid. Would I always order again
