Most desks are 28 to 30 height and I'm a short person at 5'7 so that's annoying. I keep this desk around 26 tall so my elbows are at the appropriate angles while typing now.
There's plenty of room for me to eat on it and keep a keyboard, mouse, macbook pro, and some books on the corner, nothing stacked. Really, so spacious.
It's not the easiest thing to adjust the height, but I don't plan on doing that too often. Assemblydisassembly is done with the allen wrench Ikea style. The top is pretty heavy, but with the back beam attached the legs are really stable.
