Design smarter. Prototype faster. Build with intent.

Developed as part of Skeehan Studio’s Meta Chair Project, this Chair Ergonomic Jig bridges the gap between digital design and hands-on making. Whether a furniture designer, student, or maker, this open-source CAD file gives you a practical framework rooted in human-centred design.

Inside, you’ll find:

• Ergonomic reference points that align with industry-standard postures
• Flexible configurations for various chair styles and use cases
• A repeatable workflow that enhances both digital modelling and physical testing

Crafted to be easily fabricated, this jig allows you to confidently explore comfort, posture, and proportion across your chair designs. It’s a go-to resource for speeding up your prototyping process and making your iterations more intentional.

This isn’t just a file, it’s a design foundation.
