Great as a TV stand

I flipped it on its side and used it as a TV stand. It's not the sturdiest thing in the world but it did come with a wall mount and putting books on the lower shelves helped a lot. I like the wood finish. The instruction video was easy to follow. Overall I'm really happy with it.

The Mainstays 12 Cube Storage Organizer is sturdy, easy to assemble, and looks great once set up. The cubes are spacious and fit baskets and décor perfectly, helping organize the room without taking up too much space. Great value for the price and exactly what I needed.

Just what i needed for my sewing room. One suggestion for those that purchased this, because of the dowels i used a glue when inserting my dowels to help keep them in place when assembling the cubes then i let the glue dry overnite before moving on to the sides ,top and bottom of the unit. made the rest of putting it together easier, nothing was slipping out of placement.
