Sturdy, great price.. good deal!

We stacked two of them and put them at the end of the hall, perfect fit for this awkward nook and now we've got tons of toy storage and spots for decor. These are heavy, nice and sturdy and come with the anchors you need to secure them. Great buy! (Just pay attention to the wood grain on the backing and make them all the same way… my husband didn't do that😅) Easy and quick build though at a great price!
