Steelcase Leap V2 holds first at 9.4 and the ranking carries forward. The Herman Miller Fall Sale at 25 percent off runs five more days to 22 September, and plenty of readers will have a new chair arrive in the next few weeks. So today is about the ten minutes after unboxing, because a premium chair set up badly feels like a cheap one.
Do it in this order. Start with seat height: feet flat, thighs roughly level, knees at or slightly below hip height. Then seat depth, which most people skip. Sit all the way back and leave two to three finger widths between the seat edge and the back of your knee. The Leap V2 and the Aeron both let you get this right, which is a large part of their 9.7 and 9.5 ergonomics scores.
Next, lumbar. Move the support until it meets the curve just above your belt line. On the Leap V2 you also set lower back firmness separately, and I would start soft and add firmness over a week. Then armrests: lower them until your shoulders drop and your elbows rest lightly at desk height. Arms set too high are the main cause of the neck ache people blame on the chair.
Finally, recline tension. Lean back and adjust until the chair follows you with light pressure and holds you upright without effort. A chair that locks you rigidly upright loses most of what you paid for, since movement through the day is the point of a good mechanism.
For shoppers still deciding before 22 September, the Aeron at 9.3 leads fit at 9.7 with three shell sizes. On a budget, Steelcase Series 1 at 8.7 carries a 9.7 value score and covers every adjustment above.
