These storage boxes have to be assembled and it will take you one or two box assemblies to get the hang of it. I had previously purchased another brand name box(Bankers Boxes) and these Staples boxes were cheaper when they went on sale so I thought I would give them a try. The box itself seems to have the same qualities as the Bankers Boxes and they are also cheaper and appear to have the same qualities. They appear to support one another when stacking them for storage. So I would recommend them.
These boxes suit my need very well for balancing economy with doing the job. I store standard files and folders that I will hopefully never need again but must keep for legal reasons. They stack well two or gingerly three high. I would NOT recommend any higher for papers or the bottom row may collapse.
