Sturdy, soft, doesn't smell like some new semi-synthetics. The easiest way to put this together is to put the seat upside down on a chair with no arm. The instruction sheet (only 1 page & loose) is clear and concise but brief. Just sort the bolts, there are two sizes and it matters. Only 12 screws - 6 for the arms - EASY; 4 for that "lever controls module" heavy but easy when on the chair (only aligns one way so you can't mess it up) and finally the two for lumbar support also easy. Only one note - if you're less than 5' 2" your fee won't touch the floor, but you might rest your feet on the legs.
