IKEA makes some very functional, affordable and easy to assemble furniture. The IKEA Expedit bookcase comes in many different colors (beech, birch, black-brown and white) and sizes (8, 16 and 25 squares).
Make sure you read the directions. Do not tighten the outside the screws too tightly on the outside pieces during the final steps of assembly. This can sometimes cause problems since the shelves do not always line up. Make sure you have two people during assembly. This is very difficult to do with just one person.
The big 25 square shelving unit is almost impossible to setup with just one person.
