Most chair marketing describes features. What you actually need to know is which features change how you sit, and that is a much shorter list.
Start with your measurements, not the chair
Two numbers decide most of it: your height, and your lower-leg length from the floor to the back of your knee. The second determines the seat height you need, and it varies more between people of the same height than you might expect.
If your seat cannot go low enough for your feet to sit flat, you will perch forward off the backrest all day and the chair’s lumbar support becomes decorative. If it cannot go high enough, your knees rise above your hips and your pelvis rotates back.
The four adjustments that carry the benefit
- Seat height — feet flat, thighs roughly parallel to the floor.
- Seat depth — two to three fingers between seat edge and knee.
- Lumbar height — support landing in the curve, not above or below it.
- Armrest height — forearms supported with shoulders relaxed down.
Everything else is refinement. Useful refinement in some cases, but refinement.
What the recline mechanism tells you
A cheap chair reclines against a spring you tension with a knob, and you have to re-tension it whenever the load changes. A better one is weight-responsive: it uses your own body weight to set the resistance, so it is correct without being adjusted. This sounds like a small convenience. In practice it is the difference between a chair you recline in regularly and one you set upright and leave.
Working out your budget honestly
Divide the price by the expected service life rather than comparing sticker prices. A chair with a twelve-year warranty at four times the price of one with a one-year warranty is not four times the cost per year — it is roughly a third of it, assuming both last as long as their warranties imply.
That calculation only holds if you actually keep the chair, so be honest about whether you will.

How many adjustments does a chair actually need?
Four carry most of the benefit: seat height, seat depth, lumbar height and armrest height. Beyond those, additional adjustments have diminishing returns for most people. A chair with those four and nothing else will fit a wider range of bodies than a chair with ten adjustments that omits seat depth.
Does chair weight capacity matter if I am well under it?
Yes, indirectly. Weight rating is a proxy for frame and cylinder construction. A chair rated well above your weight is usually built with a stronger base and a better gas lift, which is the component most likely to fail. It is a rough signal, not a precise one, but it is a real one.
