Aeron Chair Serial Decoder

A single-purpose web app that decodes Herman Miller Aeron chair serial numbers to reveal their complete configuration and specifications.

What It Does

Enter an Aeron chair serial number (found on a label underneath the seat) and the decoder will reveal:

• Model - Work Chair, Stool, ESD variant
• Size - A (Small), B (Medium), or C (Large)
• Height Range - Low, Standard, or High
• Tilt - Standard, Tilt Limiter, or Tilt Limiter + Seat Angle
• Arms - None, Fixed, Height-Adjustable, Pivot, or Fully Adjustable
• Back Support - Basic, PostureFit, Adjustable Lumbar, or PostureFit SL
• Finishes - Frame, Chassis, Base, and Armpad colors
• Casters - Type and floor compatibility

How It Works

The decoder parses serial numbers by sequentially extracting configuration codes and validating them against data from the Herman Miller Aeron Chairs Price Book (October 2025).

Serial numbers encode product configurations in a specific order:

AER1 B 2 3 D A LP VPR SNA SNA DC1 DVP
│    │ │ │ │ │ │  │   │   │   │   └─ Armpad finish
│    │ │ │ │ │ │  │   │   │   └───── Casters
│    │ │ │ │ │ │  │   │   └─────── Base finish
│    │ │ │ │ │ │  │   └─────────── Chassis finish
│    │ │ │ │ │ │  └─────────────── Frame finish
│    │ │ │ │ │ └────────────────── Back support
│    │ │ │ │ └──────────────────── Armpad upholstery
│    │ │ │ └────────────────────── Arms type
│    │ │ └──────────────────────── Tilt
│    │ └────────────────────────── Height adjustment
│    └──────────────────────────── Size
└────────────────────────────────── Model

The decoder handles:

• Variable-length codes (2-3 characters per field)
• Size-dependent validation (height ranges vary by chair size)
• Conditional fields (armpad finish only appears when arms are present)
• Invalid combinations (not all finish combinations are valid)
