I'm really glad I bought the bed base, the only of Fankenstolz (Frankenstolz 98160-60383-11 multizone base frame / fan Dream Flex Plus KF / 90 x 200 cm) but he was a disaster. In the first, and also at the 2nd (replacement of Amazon) slats were bent. Amazon was once again exemplary, sent back and purchase price refunded. So I was able to, thanks to the many positive reviews, order the great slatted frame and am more than satisfied. With me creaks or rattles nothing, head and footboard can be adjusted well. The many hardness settings in the pelvic area can be adjusted well and you can tell the difference. The Schultereinsinkbereich is perhaps a little too hard for me, but that is subjective. I do not know if there are bed frames where you can adjust the shoulder area individually, possibly yes, a little tip for optimization. But as I said I am very happy with the slatted base, and that made me also moved to write my first review. The delivery was also top, the driver has taken with the package even into the bedroom. The slatted frame was packaged very well. The many positive reviews are therefore absolutely justified and I can only say necessarily buy !!!
