Most developers blame fatigue on code, meetings or screens.
In reality, it’s often your chair setup quietly wrecking posture, breathing and focus.
Good news: you don’t need a new chair.
You need five correct settings.
Below is a developer-friendly, no-BS setup for long coding sessions.
The Goal (30 seconds)
Neutral posture. No pressure points. No forced “perfect sitting”.
You’re aiming for:
- Feet flat on the floor
- Hips slightly higher than knees
- Natural lumbar curve supported
- Shoulders relaxed
- Head floating above the spine
1. Seat Height (the foundation)
Rule: hips ~2–3 cm higher than knees.
Why it matters:
- Opens the hip angle
- Prevents lower back collapse
- Improves breathing and focus
Quick check:
- Feet flat
- No pressure on heels or knees
- Shins roughly vertical
Desk too high?
Fix the chair first. Then adjust armrests or use a footrest.
2. Seat Depth (the silent killer)
Wrong seat depth causes numb legs and slouching.
Correct setup:
- Sit all the way back
- Leave 2–3 finger widths between seat edge and knee crease
Too long = circulation problems
Too short = unstable pelvis
3. Lumbar Support (don’t overdo it)
Lumbar support should support, not shove you forward.
Correct feeling:
- Gentle, noticeable support
- No sharp pressure
- No forced hollow back
Strongest contact is usually around L3–L5, just above the belt line.
If it hurts after minutes, it’s too much.
4. Armrests (shoulders decide)
Armrests are optional. Shoulder tension is not.
Set them so:
- Forearms rest lightly
- Shoulders stay down
- Elbows stay close to the body
Pro tip:
Smaller keyboards (TKL / 65%) reduce mouse reach and shoulder load.
5. Backrest & movement
Static sitting kills even perfect setups.
What works:
- Backrest resistance matched to body weight
- Lean back regularly
- Micro-movements every 20–30 minutes
Think movement frequency, not posture perfection.
The 1-Minute Developer Check
Once a week:
- Shoulders creeping up? Fix armrests.
- Lower back pressure? Adjust lumbar height or depth.
- Haven’t leaned back in an hour? That’s the bug.
Why this actually matters
In teams we typically see:
- Less lower back and neck pain
- Longer focus windows
- Fewer end-of-day crashes
All from 20 minutes of setup and tiny movement habits.

No fluff. Just mechanics.
Final thought
The best chair is the one that’s correctly adjusted and used dynamically.
Your code isn’t the problem.
Your chair probably is.
