When I first assembled it, I was worried about the strength of the chair because the top and bottom pedestals were not fixed in place, but only held in place by the rods. After assembling it, I tried carrying it while holding down the pedestals, which came loose, and setting it up, but it wouldn't stand up at all! I panicked. After a few attempts, I placed the bottom part in the desired location, then extended the top part slightly longer than planned, and when I put it in the position I wanted to set it in while it was still contracted by the spring force, it was firmly fixed in place. I have the impression that it is worth the price.
