Sturdy metal construction, easy assembly, durable parts. If I have any complaints, it's that the seat height adjustment is a bit sluggish. This is nothing more than a threaded rod that attaches to the seatpost. My son is tall and heavy (at 3 most people think he's 5) and the stand tends to sag and needs to be lifted every few days. It's fine and a functional solution to "infinite customizability" but annoying, to say the least. Phone call. it's good that "lost" during assembly. ;-)
