Question about Karup Design Japan

I just received the bed and I asked myself the same question as I live on the 5th floor without a lift. I have scanned the instructions for you, here: https://drive.google.com/file... . There are a lot of wooden dowels that you have to assemble with glue, but the bed should be stable enough without glue. The slatted frame should also not be fixed with nails. You cannot use a cordless screwdriver because the screws can only be tightened with a right-angled spanner.
