Ikea used to make little sets of drawers for storing paper/office stuff, no idea if they still do.
The first ones I got were quite sturdy and had three shelves, but then they switched to two shelves and a thinner wood, not quite so good as they are a bit "sticky". Each draw is bigger than A4 surface, and about 10cm deep. Approximately an army per shelf, depends on what it is though. They look fine on wooden bookcases or similar.
A fellow wargamer here buys these things (I think it's this maker, I'll ask):

Same idea, just more flexible. There's a shop in Leeds
If you really wanted something that would look nice, but pricey, it would be map drawers. Especially an antique one.
