Check documented compatibility
Read exactly which units can be stacked and how the manufacturer describes the connection. Similar-looking shelves from the same brand are not automatically compatible, and a generic product photograph does not establish every permitted configuration.
Compare the upper access
Assign actual shoes to the proposed upper levels and consider how you will retrieve them. Expansion that adds mostly inconvenient shelves may solve less than a wider lower unit placed along an available wall.
Include all setup requirements
Review assembly, placement and any attachment directions for the complete arrangement. Keep those requirements alongside the room measurements so you are comparing usable configurations rather than an idealized pile of empty frames.
Plan the expansion trigger
Decide what change would justify adding a unit: another person, a seasonal collection or a larger active rotation. If the current problem is simply unresolved shoes accumulating at the door, more shelves may delay the needed collection review.
A two-unit stack may suit a narrow wall when its documented setup and upper access work, while one wider low rack could be simpler when wall length is available.
