📐 Ideal Sitting Posture
Monitor at Eye Level
Top of screen at or slightly below eye height. Your eyes naturally look 15° downward.
Arms at 90–110°
Elbows close to body, wrists straight and neutral — not bent up or down.
Natural Spine Curve
Lumbar support fills the inward curve of your lower back. Don’t slouch or over-arch.
Hips at 90–110°
Thighs roughly parallel to floor. 2–3 finger gap between seat edge and back of knees.
Feet Flat
Both feet rest flat on the floor or on a footrest. No dangling or crossing.
✅ Do This | ❌ Not This
Monitor Height
✅
Eyes look slightly DOWN
Screen at or just below eye level — natural, relaxed gaze
❌
Head tilted down = PAIN
Laptop flat on desk forces 40° neck bend all day
Keyboard Position
✅
CLOSE — 4–6 inches from edge
Elbows bent, shoulders relaxed, forearms supported
❌
FAR AWAY = shoulder strain
Reaching forward constantly overloads neck & shoulders
Chair Height
✅
Feet FLAT on floor
Thighs parallel to floor, weight evenly distributed
❌
Feet dangling = back pain
Chair too high compresses thighs and strains lower back

👀 The 20-20-20 Rule (Eyes)
20
Every 20 minutes
20 ft
Look 20 feet away
20 s
For 20 seconds
Prevents eye strain and gives your neck muscles a vital rest
💺 Chair Adjustment Points
Backrest — 100–110° Recline
Slightly reclined reduces disc pressure. Avoid sitting bolt upright (90° is too tense).
Lumbar Support — at Belt Line
The lumbar pad should fill the inward curve of your lower back — not your mid-back.
Armrests — Lightly Supporting
Forearms rest lightly — not propped up. Shoulders should remain relaxed and down.
Seat Depth — 2–3 Finger Gap
Fit 2–3 fingers between the edge of the seat and the back of your knee.
Seat Height — Feet Flat
Adjust so both feet rest flat. Thighs roughly parallel to floor. Use a footrest if needed.
💻 Laptop Setup = 3 Essentials
1
Laptop Stand
Elevates screen to eye level. Eliminates neck flexion. Essential.
2
External Keyboard
Positioned close to your body — 4–6 inches from desk edge.
3
External Mouse
Placed directly next to the keyboard. No reaching.
⚠ WITHOUT THESE = GUARANTEED PAIN
✋ Quick Measurements
Arm’s Length
Monitor: 50–70 cm
Fingertips should just touch the screen
Two Fingers
Seat-to-knee gap
2–3 fingers between seat edge and knee
Hand Width
Keyboard edge: 4–6 in
Your hand width = keyboard-to-edge distance
Eye Level
Top of monitor = eye height
Close eyes, open — that’s your level
🚨 Pain Warning Zones
Neck Pain
Monitor too low or too far away — forces forward head posture
Shoulder Pain
Keyboard too far away — constant reaching strains traps & rotator cuff
Lower Back Pain
No lumbar support or slouching — disc pressure increases 40% when slouched
Wrist Pain
Keyboard feet raised (tilted up) — keep keyboard flat or negative tilt
Leg / Foot Pain
Chair too high, feet dangling — compresses thighs, restricts blood flow
Eye Strain
Screen too close, glare, or brightness — use 20-20-20 rule
✅ 30-Second Posture Check
Run through this every 30 minutes:
Feet flat on floor?
Sitting back fully in chair (back touching backrest)?
Shoulders relaxed and down — not hunched?
Head balanced over shoulders — not poking forward?
Wrists straight and neutral?
Elbows close to your sides?
Eyes looking slightly downward at screen?
IF ANY ANSWER = NO → ADJUST IMMEDIATELY
⚡ Most Common Mistakes
1
Laptop flat on desk — no stand, no external keyboard
→ Guaranteed tech neck and upper back pain
2
Perching on the edge of your chair (not sitting back)
→ No lumbar support = chronic lower back pain
3
Keyboard pushed far away — reaching forward to type
→ Shoulder, upper back, and neck overload
4
Sitting for hours without movement breaks
→ Everything hurts — discs, joints, muscles, eyes
5
Monitor too low — looking down all day at laptop screen
→ Each inch forward = 10 lbs extra on your spine

🏥 When to Get Help
See an osteopath if you experience any of the following:

⚠ Frequent headaches — 3 or more per week
⚠ Lower back pain that worsens during or after the workday
⚠ Wrist pain, tingling, or numbness in the hands or fingers

Don’t wait for pain to become chronic. Early treatment = faster, more complete recovery.
