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.

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.

easy peasy

Very simple to put together I purchased this for my 68 year old mom to organize her closet. She had no issues. I believe one of the edges were a bit raised, she had no real concerns other than that. She appreciated the video that was placed on the listed.
