Nothing jars you like your chair giving way, grumbling that they should have made it out of metal, and going to inspect the damage, only to find it is metal, and the weld's given way.
Sheesh. I'm not above this thing's weight specs either. I mean, I'm right on that line, and I do wish I'd gotten the XL, but its proportions might have made things worse anyway, so... Weird limb proportions gets me again!
Thankfully I got that free 5 year extended warranty though. Would have been almost exactly 3 months after the original 3 year warranty would have ended, and that would have been some bullshit.
