This "office chair" from Ypsilon looks like it is ready to transform into a kitten-eating robot at any second. All of those knobs and levers don't morph this thing into a robot, they simply adjust the 10 different setting that can be adjusted. Here be the big list of everything that can be tweaked: seat height, depth, height of back, headrest, backrest pressure, backrest position, lumbar support, armrest height, armrest angle and armsupports. Rest assured that after you get this chair tweaked to your liking, after hours of sitting up and down testing it, it may actually be comfortable.
