However, I could not solve the problems: slatted gekürtzt by 1 cm (sawed = Bye guarantee), screws tightened (but can not be tighten properly) and the Verstelllaten I removed.
In my opinion, the adjustment is unnecessary and rather disturbing. With a 7-zone latex mattress, I had always felt to me like someone print in the ribs or I would hang out with the back of a stone. No matter what setting I tried, it did just the Verstelllatten remove (these are the slats, which are also among the ordinary slats and are held by the Verstellgummis). Now I'm lying but super!
One could do without the adjusting un-Kompfort - and the rust it can offer a few euros cheaper.
