The assembly was for me, as practiced Ikea customers, not too heavy. If it is possible to combine the first floor, on it goes quite well, only you have to bend slightly right with your fingers the tabs to fit into the column also. The floors are also quite good, but the whole structure must be anchored to the wall, otherwise 175 kg (ie CA 30.kg/Boden) pure Ilussion. If you are not careful, the tongues can bend quite ugly, so you need also a vice or pliers good. In any case, as a couple, the structure is a game I have also managed to hold objects.
