"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!

they stack on top each other great, easy to assemble and holds many hard cover books without getting the sag and warp. they hold up extremely great, there is no difference between the ones I bought 5 years ago and the ones I just got which is fantastic for the growing home library that fills the wall in my daughter's room. the only thing I wish is the backing covered the whole back and not just every other cube. will definitely purchase again
