"Backpack Storage Center"

Diy-ed it to be a backpack "locker" station for this upcoming school year since I'll have 1 in TK and 1 in 1st grade and I didn't want to have EVERYTHING from school land on the dinner table every day after school. Look's like it'll work to hold backpacks, jackets, and bins for paperwork etc...

Sturdy and easy to assemble.

This unit is the most sturdy I have put together in many years. I have recently moved and have put together many, many items like this recently. It is really sturdy and looks great. It uses actual screws and nails. The directions were easy to understand and follow. This was a great purchase!

Let me save you time. To build this with only 1 person, lay the top and sides near each other, then put the screws in so the top and sides stay together. Then add the center pieces on the row, then add the next shelf (C), put it in place then screw it in again. Other than learning how to build this the hard way, it's worth the money.
