These chairs require careful assembly and calibration to ensure optimal functionality and user experience. This guide provides detailed, step-by-step instructions for assembling and setting up both the Aeron Classic with PostureFit and the Embody chair, based on the official documentation and assembly instructions available from Herman Miller and its affiliated resources.
Whether you are a first-time user or an experienced DIY enthusiast, following these instructions ensures a smooth and safe installation process. The guide includes detailed breakdowns of unboxing, component identification, assembly procedures, and final setup, with specific focus on the unique features of each model.
Unboxing and Component Identification
Before beginning the assembly process, it is essential to verify that all necessary components are included in the packaging. This step ensures that the chair can be assembled correctly without the need to source additional parts.
Aeron Classic with PostureFit Edition
The Aeron Classic PostureFit model comes in a box containing the following components:
- Fully assembled seat and base
- Separate backrest
- Casters
- PostureFit lumbar system
The seat and base arrive pre-assembled, but the backrest and casters must be attached manually. The PostureFit lumbar support is an optional feature and requires specific installation depending on the model (Model A or Model B).
Embody Chair
The Embody chair includes a more complex set of parts, as it is designed for advanced ergonomic customization. The box typically contains:
- Chair parts: Spine, back, and backrest
- Assembly tools: Two Allen wrenches (T27 and T40), back bolts, metal rod for spine assembly, two plastic hinges, and screws
- BackFit adjustment knob
All tools required for assembly are included in the box, and no additional hardware is necessary.
Installing the Casters on the Aeron Classic
One of the first steps in assembling the Aeron Classic is installing the casters, which provide mobility and stability. The process is straightforward but must be performed with care to ensure proper seating.
- Flip the chair upside down to access the caster attachment points.
- Insert each caster into its socket until it clicks firmly in place. This ensures that the caster is securely attached.
- Flip the chair back upright once all casters are installed.
This process ensures that the chair is stable and ready for the next steps in the assembly process.
Attaching the Backrest to the Aeron Classic
The backrest must be securely fastened to the chair frame to ensure proper support and stability. The following steps outline the process:
- Remove the four screws from the chair frame.
- Align the backrest with the holes in the frame.
- Insert and tighten all four screws securely to fasten the backrest in place.
If the backrest does not align properly, refer to the troubleshooting section for adjustments.
Installing the PostureFit Lumbar Support on the Aeron Classic
The PostureFit lumbar support is a key feature of the Aeron Classic and must be installed correctly to ensure proper functionality. The installation process varies slightly depending on whether the model is A or B.
For Model A:
- Insert the PostureFit cable into the support box.
- Remove the middle screw below the box.
- Create a small opening above that screw in the back mesh.
- Slide the cable through the mesh opening.
- Mount the central bracket and tighten it to secure the PostureFit system.
This ensures that the lumbar support is properly aligned and ready for use.
Assembling the Spine and Backrest for the Embody Chair
The Embody chair requires careful alignment of the spine and backrest to ensure proper structural integrity and ergonomic support. The process involves the following steps:
- Position the spine under the antler and dome of the backrest.
- Take the metal rod and carefully align it with the hole in the spine.
- Push the rod through the spine until it fully extends to the other side.
This step ensures that the backrest is properly connected to the spine and provides the necessary support.
Securing the Hinge Covers on the Embody Chair
The hinge covers are an essential part of the Embody chair's assembly and must be installed correctly to maintain the chair's structural integrity.
- Identify the two plastic hinge covers, noting that they are left- and right-specific.
- Align the rod inside both hinge covers and push them firmly into place.
- Ensure the hinge covers snap securely around the rod.
Once the covers are in place, the chair is ready for the next step in the assembly process.
Locking the Spine Assembly on the Embody Chair
After the hinge covers are in place, the next step is to secure the spine assembly using the provided Allen wrenches.
- Insert bolts into the holes on the left and right sides of the hinge covers.
- Use the T27 torque Allen wrench to tighten the bolts securely.
- Apply downward pressure while tightening to ensure a snug fit.
This step is crucial to maintaining the chair's stability and preventing any movement during use.
Attaching the Backrest to the Base on the Embody Chair
With the spine and hinge covers in place, the backrest can now be attached to the chair base. The following steps outline the process:
- Align the two holes at the bottom of the backrest with the protrusions on the chair base.
- Push the back firmly into place, ensuring a proper fit.
This ensures that the backrest is securely attached and ready for final tightening.
Securing the Backrest to the Base
Once the backrest is in position, it must be secured to the base using the provided bolts and Allen wrench.
- Insert and tighten the bolts to fasten the backrest to the base.
- Ensure all bolts are tightened securely to prevent any instability.
This step is essential for ensuring the chair's stability and long-term durability.
Final Assembly and Calibration
After all components are assembled, the chair must be calibrated to ensure optimal comfort and functionality.
- Test all chair functions, including height adjustment, lumbar support, and recline.
- Ensure all bolts are tightened securely to avoid any instability.
For the Aeron Classic with PostureFit, it is important to confirm whether the model is A or B and follow the appropriate calibration steps. This ensures that the PostureFit system is properly adjusted and functioning as intended.
Troubleshooting Common Issues
During the assembly process, some challenges may arise. The following are common issues and their potential solutions:
- Misalignment of the backrest: If the backrest does not align properly with the chair frame, refer to the troubleshooting section for adjustments.
- Loose bolts: Ensure all bolts are tightened securely to prevent instability.
- Caster movement or instability: Check that each caster is securely inserted into its socket and that the chair is placed on a stable, flat surface.
If issues persist, users are encouraged to refer to the official Herman Miller support resources for additional guidance.
