Very good bed with good instructions but they are in German (but pics easy to understand).  Tip: when making the triangles for the upper part, take care to ensure the holes at the apex on each triangle align to allow you to fit the support bar correctly.  There are two holes (dowl and screw) with a corresponding set of holes at the end of the support bar.  Get them the wrong way round and the bar won't fit.  Tip 2: use a cordless drill with allen key attachment, there is a lot of screwing.
