Lots of adjustable settings - seat height, seat slope, back height, back slope. Armrest height is adjustable, too, although the lowest setting might be a little high for a really short person (I'm 5'10"). The highest armrest setting would accommodate a NBA player.Only used it for 2 days so far, but seems very comfortable and sturdy. A cinch to assemble; took maybe 15 minutes with only the supplied Allen wrench needed. Took longer to remove all the packing.
