The Songmics Sophia is a fixed 4-drawer shelf, no two units can be combined to form a 5-drawer system. Each unit consists of 4 drawers that do not stack into each other to create more drawers.

Yes, you can also assemble the Songmics Sophia niche shelf with just 2 drawers. The shelf consists of two stackable modules that are simply plugged together. If you only use one of the modules, you get a half-height shelf with 2 drawers. This gives you the flexibility to adjust the height to your needs.
