Chair Adjustment Guide
Personalising your seating experience
Your Chair is Pre-Customized
Your chair's seat foam density, cylinder sizing, and armrest width have been custom-set to your measurements. This guide covers the adjustments you can personalize yourself. Allow 7-14 days to find your optimal settings.
Key Ergonomic Principles
The 100-110° Rule
Avoid sitting at exactly 90°. A slight recline (100-110°) reduces disc pressure by up to 25% and promotes spinal health. Have someone check your angle from the side.
Partner Check
Ask a partner to visually check your posture from the side. They can confirm your hip angle, lumbar curve, and whether your ears align over your shoulders.
Headrest Purpose
The headrest is designed for reclined positions only — breaks, calls, or reading. During active desk work, your head should be self-supported.
Movement Matters
No posture is perfect for 8 hours. Shift positions regularly, use the recline feature, and take micro-breaks every 30-45 minutes.
Start here — these form the foundation of your seating position
Seat Pan Adjustment
Height & Depth Control
Seat Height
Locate the lever on the right side of the seat. Pull up while seated to lower, stand and pull to raise.
Seat Depth
Pull the slider handle under the front of the seat to unlock. Slide forward or back (5cm range), then release to lock.
✓ Goal
Feet flat, knees below hips (100-110°), 2-3 finger gap behind knees.
Lumbar Positioning
Lower Back Support
Height Adjustment
Grip both sides of the backrest firmly and lift. You'll feel it click into position. Lift all the way up to reset to lowest position.
✓ Goal
Lumbar curve should fill the hollow of your lower back without pushing spine forward.
Recline Control
Backrest Angle
Lock Mechanism
Locate the wire loop on the left side. Pull up to unlock recline, push down to lock. There are 4 locking positions.
✓ Goal
Slight recline (100-110°) reduces disc pressure by up to 25% vs sitting at 90°.
Back Support Tension
Recline Resistance
Tension Knob
Locate the knob under the seat. Turn clockwise to increase resistance, counter-clockwise to decrease.
✓ Goal
Match to your body weight — supportive enough to stay upright, easy enough to recline smoothly.
Fine-tune these for additional comfort
Armrest Height
Vertical Adjustment
Up & Down
Press the button on the outside of the armrest while pushing up or down. Release button to lock.
✓ Goal
Elbows at 90-100°, shoulders relaxed (not hunched or raised).
Armrest Depth
Forward & Back Position
Slide Adjustment
Simply push or pull the armrest pad forward or backward. It will slide and hold position.
✓ Goal
Support forearms near keyboard without pushing shoulders forward.
Neck Rest Height
Vertical Position
Up & Down
Grip the neck rest and push up or pull down to adjust height. It will hold position.
ℹ️ Important
The neck rest is designed for reclined positions only — use during breaks, calls, or reading. During active desk work, your head should be self-supported.
✓ Goal
Position at the junction of head and neck (between skull base and shoulders), not mid-skull.
Neck Rest Tilt
Angle Adjustment
Forward & Back
Tilt the pad forward or back to angle it. Match your natural head position when reclined.
✓ Goal
When reclined, supports neck without pushing head forward. Maintains neutral alignment.
Troubleshooting
Lower back aching after sitting?
→ Raise the lumbar support. It should fill your lower back's natural curve, not sit below it.
Shoulders feel tense or hunched?
→ Lower the armrests. They should support your forearms without lifting your shoulders.
Numbness or tingling in thighs?
→ Slide the seat pan back or lower the seat height. Ensure 2-3 finger gap behind knees.
Neck strain when working?
→ Don't use the neck rest for upright work. It's designed for reclined positions only. Check monitor height instead.
Chair tips forward when you recline?
→ Increase the tension knob (turn clockwise) to match your body weight.
