I weight just around 70kg and I broke two in an hour by just standing on them. I'm quite scared using them now.

I don't think standing on them is what they're designed for, that strains even the best built chairs. The interesting thing about this chair I think is its relative strength compared to the absolute dearth of materials used, not its absolute strength, in my opinion — it won't ever be a strong as a steel chair, sure, but that is not why these things are remarkable.

  From my experience, they can be stronger than a steel chair. The cheap ones at least. I had many steel chairs break at the welds. Or have the legs bent. For example, if you balance on the back legs, both the steel and plastic chair may collapse, but the plastic chair will keep its shape afterwards, while the steel chair may stay bent or break.

My memories of monoblocs suggest that the problem is less that the chair can't take the strain of being stood on, and more that it can't take the strain of being climbed onto. They're not rigid bodies; getting on to one to stand up will shake the seat around like crazy. Most chairs are much more physically stable.

Chairs are designed for someone to sit on, not stand on. When the first chair broke due to the extreme concentration of weight in one spot, that should have been a sign not to abuse the second chair in the same way.

  If the legs broke it probably wasn't weight concentration but just embrittlement due to UV and weather exposure. In my experience that's how most of these chair break, at the legs not in the seat.

  Its a question of tolerances, if they break when someone stands on them they there is a decent chance they will break when you sit on them, or sit down too fast, or sit on them on uneven ground that distributes slightly too much weight to one leg, or they have been in the sun too long and have become brittle. I'm a relatively tall guy and am wary sitting on these, standing on them would be certain failure. They are essentially cheap trash that will spend ~12 months looking like a chair and 500 years looking like a broken chair in a landfill.

I've consistently weighed between 80 and 95 kg over the past 25 years, and have never broken one of these chairs by sitting in them. I don't think I would risk standing on one, though.
