Yes! I have 2 of those SAME EXACT chairs! Sitting in one and leaning back, the backrest area starts to twist slighly and feel like it could move to the left or right with very little pressure.
I have used this chair as a stepladder, standing on the seat area, and I couldn’t consentrate on the task I was to perform just above me because all I could think about is that this flimsy chair is going to explode into many green plastic pieces any second!
I plan on giving them away to a long time friend that I realy don’t like anymore.
