The package weighed about 40 kg (2x2m, including packaging. Specifying 85kg * is corrected *) and I've worn alone and built up in my apartment. Takes about 30 minutes and you should have a wooden or rubber mallet to secure the feet.
So far, the bed makes a very stable and solid impression.
Point deduction there because of the lack of instructions. Although there are indications to the material wood in 3 copies here, but where that screws come, you have to find out for yourself. That's the other reviewers, as well as me did succeed manual belongs to yet.
UPDATE: An employee of the seller now has contacted me and explained the discrepancy of weight. Very attentive and customer-oriented!
Due to the good customer service there despite the lack of instructions 5 Stars.
