The first contact point for me was Amazon, since a fast delivery and good customer service are guaranteed (in the case of Reklamtionen). After my choice was made I've bestelllt and have to say that I am so far disappointed in any way.
The slatted frame is solid, the engine is very quiet, the remote control does not look cheap and responds very well. You can either adjust only head or foot or via a third button both simultaneously. What immediately noticed very positive to me, is the angle of inclination of the head part. This is not simply erect (like my old slatted frame) but has in the upper part again an extra inclination (with rocker), as a headrest, so to speak. That's definitely very enjoyable and useful, because without this feature you sit upright while, but the head falls backward into the void or you have to pinch a pillow in between what one but often then coat the top and then falls away. I speak here from experience really, just that made me extremely disturbed at my old slatted frame, so that I no longer even set up the headboard in the form at the end.
From me, there are five stars, because there is also a critical eye not what I would have to complain about.
