Are these safe to stack in storage, or would it cause damage to the lower box?

It would more sturdy than a cardboard box but it does have wheels on the bottom so the one without wheels maybe better for stacking

I have not tried it but I am sure if you put two heavily loaded Vaultz boxes on top, it will cause some damage. Big question would be how heavy will the top be.

Depending on the weight they should stack successfully. You haave to be aware of the csters though.

I would not climb or set on these because they are not made that sturdy. I don't think they would stack very well. They are all the same size. I like them for storage that are set in shelves.

Yes, no need to worry. I ordered one for my daughter. She loved it so much I am ordering two more, to do exactly what you want to do, stack them.

Yes, you can. They don't sit in each other completely but they do stack for storage.

I havn't tried stacking them...but I think they would stack very well...the rubberized material on the top would keep them from sliding, and there isn't anything that would interfer with the drawer opening/closing.

I'm not sure you can safely stack them. I don't think they're made to be stacked (they don't lock together for stacking). The unit isn't small .. it stands about 3' feet tall. My fear would be if you opened the top drawer on the one you stacked on top, the unit could fall on top of you.

Since there's nothing in them that's perishable u should be fine. When left unassembled they are stackable.

I have only placed them in the upper rack. I wouldn't put them in the lower one.

If I wanted to stack them and they didn't make good contact, I'd simply make my own connector and put it between them. I suppose as long as they're PCB protected, there should be no problem.

I think it would be fine to stack them, assuming they aren't packed with anything too heavy. The folders/frame don't hang over the edge of the file box, so they shouldn't be affected.

I don't think these are stackable. There is no mechanism that allows the top one to rest on top of the lower level. They would slide into each other.

I think if the bottom is weighted down good you could stack another on top with light weight items only, otherwise I would say No...I love these, but I would not trust them 100% for stacking. I have a whole wall of them in my kitchen for spare appliances, cookbooks, phone books, etc....it looks neat and organized.

They stack great. We have three of them, and there are no problems. The legs of each fit into slots in the tops of the others, making a very sturdy stack.

No, they would not stack well.....and you can make them into a good chair if you put in your own sheet metal screws in the underbar. Now, it is sturdy, where before it collapsed on us.....it just needs some TLC to be a safe product. Enjoy.

No. They stack on top. Whatever's inside would be safe as long as it isn't taller than the sides of the tray.

I personally do not stack mine. They are fragile. Plus, they are not all exactly the same dimension. They don't easily "fit" in one another. They're beautiful, but high maintenance!

I don't have any of the large flip top storage boxes so I can't tell you for sure but they stack VERY, VERY WELL with themselves. I wouldn't trust the "nesting" in an earthquake and I wouldn't expect them to remain stacked after a drive across Kansas but for sitting on the shelf or carrying several stacked units from the basement to the garage they stay together. I'll edit this answer to add that according to Amazon's reported measurements, the large box is longer (obviously) and wider. I'd bet the smaller box would stay put just fine with the feet on the larger lid, again with exception to earthquake, etc.
