Anatomical Ergonomic Chair Concept

This project explores what happens when a chair is designed like a human skeleton rather than a rigid piece of furniture. The Anatomical Ergonomic Chair uses articulated joints that mirror the motion of real human joints, allowing the seat, backrest, and arm supports to move naturally with the user.

The chair structure is built from multiple modular components that can be 3D printed individually and assembled afterward. Each segment corresponds to a major part of the body: a flexible spine-like backrest, shoulder-style arm joints, and a hip-style pivot between the seat and stand. These articulated sections allow controlled movement while maintaining support.

At the base of the design is a pivotal stand that acts as the central balance point. The stand allows tilt and rotation so the chair can be adjusted to different sitting angles. Locking joints enable the user to fix the chair in a comfortable position or allow slight movement for dynamic sitting.

The model is intended as a conceptual exploration of ergonomic furniture and human-inspired mechanical design. It is suitable as a display prototype, a design study, or a modular experiment for testing articulated 3D printed joints.

All parts are designed to be printable on common desktop 3D printers. The model can be printed in sections to fit smaller build plates and assembled using pins or screws depending on the builder’s preference.

Normal supports work best for 3d printing this project as i can guess because i am unable to slice this on my pc to tell accurately because of my shitty gpu.
