Now every time I look at an aluminium ladder I will be tempted to cut it into pieces with my einhand winklescheifer to build a Sprossenwand !another simple solution is getting a aluminium ladder ( a tested one about 150kg reliable, maybe sawed at length to fit into a room ), about 4 screws, a few washers, a few nuts, 4 dowels. A little bit of drilling ability, and ready to go.
All attached to a sturdy wall. I do not have experience with a freestanding rack, but I want a unshakable one.
