How to Set Up Your Chair for Optimal Ergonomics

Getting your chair height, lumbar, and armrests right makes a significant difference in comfort over long work sessions. Here's a simple step-by-step setup guide.

Step 1 — Seat Height

This is the most important adjustment. Your seat height affects your leg angle, hip position, and how you hold your arms relative to the desk.

1. Feet flat on the floor

Adjust the seat so both feet rest flat on the floor (or on a footrest). Your knees should be at roughly 90° and level with or slightly below your hips.
 

2. Check knee angle

A 90–100° angle at the knee is ideal. If your knees are higher than your hips, raise the seat or lower the desk.
 

Step 2 — Lumbar Support

The lumbar support should sit in the natural curve of your lower back — roughly at belt-line height. If your chair has adjustable lumbar height, slide it until you feel gentle, continuous contact without pressure. You should not have to lean back to feel support; it should be present when sitting upright.

Step 3 — Armrests

With 4D armrests (Apex Glyder), adjust so that:

  • Arms rest at elbow height when shoulders are relaxed (not raised or dropped)
  • Forearms are roughly parallel to the desk surface
  • No gap between your elbow and the armrest when typing

Step 4 — Monitor Alignment

Once your chair height is set, adjust your desk and monitor:

  • Monitor top should be at or slightly below eye level
  • Screen distance: arm's length away (roughly 20–28″) depending on screen size
  • If using a laptop, a laptop stand or external monitor at proper height is highly recommended
 

✅  Quick test: Sit in your normal working position, close your eyes, then open them. Your gaze should naturally fall on the top third of your screen. If you're looking down significantly, raise the monitor.
