I'm using two sets of 39 x 18 and 39 x 24 stacked on top of each other in my closet. If you then extend the Nitori [stretchable closet hangers] to their maximum width and place them on top, you can get the perfect length. By hanging T-shirts etc. on the hangers at a lower position and storing trousers, socks etc. in the storage case, we were able to transform the closet into one where our two young children can easily choose their own clothes. We added the optional casters, so it's easy to move around and clean. It was cheaper than buying wooden drawers, and if the drawers become too small as the children grow, you can buy more and stack them on top of each other, so I'm very satisfied. Please keep selling this for a long time!
