Are these sturdy enough to resist to multiple fall down?

I feel they are. We have hardwood floors and my 3 year old little boy drops them all the time. Granted it isn't from very high up :)

They are fairly sturdy but they really aren't designed for side stacking. If you are using them for something light you might be ok but I would look to in the least tie them together.

They are resistant enough to not break if dropped, and to deflect a small stone that might get kicked up while riding. This is as far as I have tested them.

I can only tell you that I had one fall off of an 8' shelf onto a hard floor, and it ended up just fine. That is the best I can offer in regard to your question, I hope it helps.

Not sure how much weight they can withstand but they are pretty sturdy. They are all metal.

They are sturdy, but they won't stand up to being thrown around. Depends on the kid.

They are fairly sturdy. Depending on how much you throw your backpack around, they should be ok.

No. They would likely fall. While I like them, I have had clothing occasionally fall off.

They're pretty thin. Maybe but would probably fall down easy. Maybe with a little double sided tape they would be ok?

They're very sturdy. Mine are stacked 4 high so far, and I would go higher if need be. I seem to recall when I was doing my research on them that someone who had written a review for Amazon talked about how high he had stacked them, so you might check out older reviews.

I've had no issues putting them on and I've dropped them a few times and no issue. I would describe myself as a bull in a china cabinet when it comes to how gentle I am with things. I would not describe these as fragile, but wouldn't expect them to completely survive a really hard slam on concrete either

They are very sturdy, like a very strong milk crate. I do not know what the safety measures are in the amount you can stack, but I would stack five with out worry.

I agree with Bruce. They are fairly sturdy, if you lay them flat they are more rigid...I would say if the weight is distributed evenly and no sharp indentations are made, they could probably support 20-30 lbs each without being damaged.

They are sturdy. As long as you don't lean on your computer they should be fine. I think they do help with air flow.I forget about the feet sometimes. I have been using the feet now since i received this email from you. lol

No, they are very sturdy, they are amazing, no issues with popping off or balance issues with the liner.... I'm very happy with them!!!! Hope this helps.....:)
