Chair explodes

One month ago, in one of the Chinese offices a chair of an accountable exploded just few seconds after she stood up. It happened because of the gas cylinder that was in the base of the chair, the part that allowed the user to adjust the seat up and down.
The explosion was quite strong; it even left some scratches on the floor.
A happy woman was so glad not to be on that chair in the moment of explosion that she put these pictures on the internet as a warning of what can happen with these chairs.
Now I’m thinking, I have almost the same chair…
