I like the idea of a stackable units, so I can build my own, but the hollow core construction, its a idea, just bad idea. Makes this feel cheap and non-durable. Got it and found the hollow pieces were all broke. The hollow pieces are the bottom and top pieces, so things can easily break through. Too much pressure on the hollow parts and it will go right through, the paper lining is the only support.If your eyeing this, please get it for light use, maybe stacking sweaters and light cloths, not good for heavy items or toys. Also be ready to get broken pieces.I was going to exchange, but now I am going to seek refund and go with a solid unit.
