Construction: Single.
The steel frame was assembled quickly, 20 screws with nuts withstand a lot of strength. Took about 15 minutes. Although in theory the steel frame could go beyond the 2m this is actually definitely limited because the central piece of the metal frame.
Hällt you look at the good and illustrated installation instructions you are done with the rest (much Fummelarbeit with the band in the middle) for another 45 minutes.
Quality (material):
Metal Frame: The frame is made of steel. The screws are thick. Nuts went well on the screw top turn. Material is also very good, the included Allen key and the combination wrench are well taken and are not slipped.
Slats: The slats themselves are quite thin and inflexible. The ends of the slats are frayed here and there and have a little chipped. Therefore, better use a mattress Schohner.
Plastic Parts: Partly lousy quality, twisted and compressed. Reinzubekommen The slats there was ne Qual. Thick minus point.
Quality (Liegekompfor):
I was rather skeptical when I saw the thickness of the individual slats. But it is pretty good. The adjustment of the lying surface in the height of the pelvis also works quite well by Steinhart to excessive force (which my mattress only to nem conscience zuläst point) is very well adjusted.
Conclusion: Very good value for money. Deductions gabs only because I was ordered to struggle myself with the plastic parts.
