On the basis of existing reviews (thanks again for that!) I ordered 2 of these bed frames. Previously, I had some experience with a "Mixrost" of Dunlopillo with disc springs and book slats. Even that was all right, but still getopt due to the all-over suspension with spring plates. As mattress serve 2 Schlaraffia Giga Plus + HG2 3. A dreamlike sleep feeling and comfort. Since I have 2 lumbar surgeries I prefer a harder attitude and have asked the lumbar area on hard thanks to the enclosed adjustment key. (There's just hard or soft!) The delivery was fast, but bad repackaged and damaged, but fortunately nothing of the grates. The freight forwarder and his other additional cargo vehicle together with something more rustic of the variety. But this will certainly vary by region. Conclusion: I have 2 Top Plate racks, perfect sleep quality. Processing, function perfectly. Equivalent grates cost of the known brand manufacturers multiples.
From me a clear recommendation Gut's Nächtle ........
