Before you start browsing different models, it's essential to think of what exactly you're going to need your nightstand for:
If you're mainly after some extra storage room, look for nightstands with two or more drawers or, for taller items, with doors;
If you want to keep a few books next to your bed or would like to showcase a few selected items, go for a model with open shelves;
the combination of a small top drawer and a bottom shelf is one of the most popular layouts.
