If you’re an engineering student or a new grad, your chair is probably whatever came with the apartment or what you grabbed from Target. That’s fine for a semester of occasional studying. It’s not fine for a full-time job where you’re at a desk from standup to EOD with maybe a bathroom break if you remember.
Poor posture from a bad chair is a real career risk. Back pain, shoulder tension, and wrist issues compound over time. The engineers I know who ignored this in their 20s are paying for it now.
Here’s the short version of what to look for — on a budget.
What Actually Matters
Lumbar support. Your lower back needs support, not air. If the chair curves away from your back below the shoulder blades, that’s the problem. Look for adjustable lumbar depth or a removable lumbar pillow as a cheap fix.
Seat depth. You should be able to fit 2–3 fingers between the front edge of the seat and the back of your knees. Too deep and you slouch forward; too shallow and you lose thigh support.
Armrest height. Elbows at 90° with your arms relaxed. Most budget chairs have armrests that are too high, which loads your shoulders. Look for height-adjustable arms — this is often the feature missing on the cheapest models.
Seat height. Feet flat on the floor, thighs parallel to the ground. If your desk isn’t height-adjustable, get a chair that goes high enough for your dimensions.
Budget Picks Worth Looking At
You don’t need a $1,400 Herman Miller to sit properly. In the $200–$400 range there are chairs with legitimate lumbar support, adjustable armrests, and decent build quality that’ll last several years of daily use.

The Honest Recommendation
Spend $200–$350 on a chair with adjustable lumbar, height-adjustable arms, and proper seat depth. That’s the minimum spec that prevents most posture problems. If you can stretch to $400, you open up chairs with better foam and more adjustment range.
Don’t buy a “gaming chair” that’s really a bucket seat — they look aggressive but have terrible lumbar support for sustained desk work.
Your chair is work equipment. Expense it if you can.
