Super easy to put together. All parts labeled with diagram, worst thing was alan key screws. Connectors for each part are metal, so it won’t fall apart when the larger cats jump on it. Ours is strapped to the wall in a stud so it won’t tip over. They’ve only managed to turn it slightly. Only one bit of fabric has come loose from a leg – easy fix with a heavy duty staple gun. Our guys and girls seem to be enjoying it!
