K&M's build quality is superb. I have a pair of low stands I use for on-stage (K&M 25950, I think) that are really solid, like nuclear bomb solid, and the knobs and other hardware are made well too. I honestly think that someone tripping over one would be more likely to go down themselves than to knock over the stand. They are heavy as hell, though. I used to have a ~4+ meter stand of theirs that was also solid as a rock. I am pretty sure that thing weighed over 20 pounds, though. If weight is a concern (I usually take public transport to shows, so I'd rather not carry a 20 pound stand), make sure you check before you order...
