Before I write an opinion, I wanted first of all to make sure the bed slats and a little test. We have this bed frames had said now since 2 weeks and as already all previous speakers or prescribing: order issued, the call forwarding with delivery specification (3 days), on-time delivery directly to the doorstep. Great service! I was a bit skeptical about whether the new bed frames let us really sleep better, since we have the conventional LIDL mattresses lying in bed. If necessary, we would else bought later new, quality mattresses, but that's not necessary at all. The different zones of the bed slats can be adjusted very easily and I'm pleasantly surprised, in which small angles you can make the head portion upward. We sleep very well and finally have no more back pain. So "thumbs up" on this product!
