Why it matters

Even a well-engineered chair won't help if it's set up incorrectly — you'll carry the same aches into a new chair. This guide covers the small, high-impact adjustments that fix the cause, not the symptom, so your chair delivers the comfort and support it's built for.

How you receive it

Place any order and we'll email your download link as soon as your order is confirmed. Open it on your phone, tablet or laptop and follow the steps as you set up your chair.

The Apex Ergonomics Pack is available only to Apex Comfort customers — not included when the same chairs are bought from general retailers or marketplaces.
