Under $200 you are not buying a Herman Miller. You are choosing which compromise you can live with for eight hours a day, and the chairs that do this well are the ones that spend their budget on adjustment rather than on looking expensive. That is the useful filter. A chair with a moulded back and a chrome base looks like a $600 chair and fits exactly one body shape. A plainer chair whose lumbar pad slides up and down, whose armrests move in three directions, and whose seat height covers a real range will fit you specifically. The four below all sit between roughly $130 and $170, and they differ in which adjustments they chose to include.
The armrests fold up out of the way, and that single feature decides whether this chair works in a small space. With them up, the chair slides fully under the desk instead of stopping four inches short. If your desk is in a bedroom corner or a hallway nook, that four inches is the whole argument. The S-shaped backrest and mesh panel handle a normal working day fine. What you give up is armrest adjustability: they flip, but they do not move in and out or rotate, so if you want your elbows supported at a specific width this is not the one. Good pick if floor space is tighter than your back is fussy.
Most chairs at this price have a lumbar bulge in a fixed position, which helps if your lower back happens to be where the designer assumed. The Ticova's lumbar pad adjusts for height as well as depth, so you can put the support where your spine actually curves. That is the adjustment worth paying for, and it is usually the first one cut. You also get a headrest that rotates and armrests that move in three directions, plus a 130 degree recline if you want to lean back and read. The mesh is firmer than the plush look of the photos suggests. That is not a fault - a seat that sags by mid-afternoon is worse - but do not expect an armchair.
This chair has been sold long enough that its failure modes are known rather than guessed at, which is worth something in a category full of six-month-old brands. A 330lb weight capacity also implies a gas cylinder and base built past the minimum, and the base is where cheap chairs fail first. The tilt lock is the underrated control here. Being able to fix the recline at a chosen angle, rather than only upright or free-rocking, is what lets you settle into a position and stay there. Armrests are 2D rather than 3D, so they move up and in but do not rotate. If you type with your elbows angled outward you will notice; most people will not.
This is the one that fits you rather than the average of everyone. Both the lumbar support and the armrests adjust in three dimensions, which means you can set the support where your back curves and the armrests where your elbows fall, independently. It is the most expensive of the four and the newest, so there is less long-term data on how it wears. The V-shaped back is a genuine design choice rather than styling - it leaves room for shoulder blades to move instead of pressing them forward. Worth the extra if you are tall, short, or otherwise not the build these chairs are designed around, because that is exactly when fixed adjustments fail you.
Buy for adjustment, not for looks. In this price range the chairs that photograph best are usually the ones that fit fewest people, because moulded shapes are cheaper than moving parts. One measurement before you order. Sit on a dining chair at your desk with your feet flat and your elbows bent to ninety degrees, and measure from the floor to the top of the seat. That is your target seat height. Every chair here lists a seat height range - if your number sits at the very top or bottom of it, pick a different chair, because you will spend the whole time at the end of the adjustment instead of in the middle of it. And if your feet do not reach the floor once the armrests are at desk height, you need a footrest more than you need a better chair.
