The slats are of good quality and it is well on it. Since there are "Basic" bed bases, I did not expect miracles, but good sleeping comfort is guaranteed. Who has specific back or other problems, maybe you should take up out uchteren variants. For the assembly of two bed frames (80 x 200), we have two of about 2.5 hours. Required (without electric screwdriver). Anyone who wants to avoid blisters on the hands, but should consciously consider the purchase of such into consideration! The instructions with color photos is a help for artisanal clever like me, after a few considerations of the assembly even without instruction possible. Technically untalented but must be something reinhängen in the manual in order to understand them. The main flow, we have somewhat simplified. 1. First, use all the rubber caps. 2. frame, incl. Header, screw together. 3. Insert the slats one side. 4. Thread the center strap. 5. Insert wooden slats on the other side. 6. Insert Fittings. 7. middle chord tension and tighten. No witchcraft. Downer: the bolts are of very poor quality. Two of them are broken. And I have not applied any force! Only screwed up to the stop, as it should be. The holes are drilled borderline, so very close. When screwing in the screws can heat up so much that they just break. I recommend you have access to a few emergency screws in the background. Otherwise, good price / performance ratio. Can be recommended.
