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.

Happy w/ 12 Cube Storage

I'm familiar with these units and was worried about damage upon delivery, unit stability and ease of assembly. Well it arrived in perfect condition. Just be careful opening and cut very close to edges because there was no easy way to open. Had some small minor surface scratches from factory but can hide during install. Directions were really clear and easy to follow. Nice to see sturdy plastic dowels. I always hated trying to use those small nails to hammer in the back panels but this item has that covered. Theres a nifty plastic nail holder that you hold to edge of shelf and keeps nail in place and every one went in with ease. For the price I am happy with purchase.
