If you’ve ever stumbled upon a heavy, cast-iron, porcelain-enamel barber chair in an old shop or an estate sale, chances are you’ve met a Koken. For decades, the Koken Barber Chair Company of St. Louis, Missouri, set the gold standard for barber furniture. Today, restoring a vintage Koken is a labor of love for many collectors.
But one question plagues every new owner: "How old is my chair?"
Unfortunately, unlike guitar collectors or car enthusiasts, Koken enthusiasts face a challenge: there is no single, publicly available "master list" of serial numbers published by the original manufacturer. However, by using patent dates, model features, and community data, we can build a "serial number list" framework to help you date your chair.
Here is how to decode your vintage Koken barber chair.
Because no official book exists, collectors rely on shared data. Below is a list of known serial numbers and their associated patent dates/models to help you compare.
| Serial Number (Approx.) | Latest Patent Date / Model | Estimated Era | Key Features | | :--- | :--- | :--- | :--- | | 1 - 5,000 | Oct 23, 1900 | 1900 - 1905 | Bicycle seat style, cast iron, very rare. | | 12,000 - 20,000 | June 9, 1908 | 1908 - 1915 | High back, ornate porcelain base, footrests with coin trim. | | 45,000+ | Aug 12, 1919 | 1920s | Heavy wood arms, "Koken" cast into the iron back plate. | | Varies (Model 11/12) | 1920s - 1930s | 1920s - 1930s | Distinctive flat armrests, single porcelain footrest. | | High 5-Digits | 1940s Patents | Late 30s - 40s | Transition to "President" model, streamlined metal. | | 6-Digits | Mid-Century | 1950s+ | Thick leatherette, more plastic components, "Imperial" styling. |
Note: This table is based on collector observations. Koken reused patent plates for years, so always trust the latest date stamped on the plate.

Late-stage Koken before the 1969 Takara-Belmont acquisition. How to Locate and Identify Your Serial Number
Primary Location: Look for a stamped number on the underside of the seat frame or on the iron base casting. You may need to lift the seat cushion or flip the chair to see it clearly.
Secondary Marks: You may also find "casting numbers" (e.g., 52CB or 1174). These are generally part numbers or model identifiers rather than unique serial sequences, though they can still help identify the model via period catalogs.
Model Indicators: Koken's name is usually prominently cast into the footrest. Value and Authenticity
The value of a Koken chair is heavily influenced by the working condition of its hydraulic lift and the rarity of its materials (e.g., quarter-sawn oak, original tufted leather).
Restored Condition: Professional-grade restorations can range from $2,000 to over $12,000 depending on the model's rarity.
As-Is Condition: Unrestored chairs with rust or upholstery issues often sell for under $500. Determine Koken Chair Age by Serial Number - Expert Guide

Mid-century styles; final years of independent Koken production. Where to Find the Number
If you cannot find the serial number, check these three common locations:
Under the Seat Cushion: The most frequent spot. It is typically stamped into the metal frame or the underside of the wood.
The Pedestal Base: Look near the bottom edge of the vertical column, where it meets the floor plate.
Underside of Footrest: Flip the footrest up; some models have a sequence stamped on the back plate.
Important Note on Casting Numbers: You may find numbers like "52CB" or "505KO". These are not serial numbers; they are "casting numbers" or part identifiers used for the manufacturing molds. A true serial number is usually a longer, 4- to 6-digit sequence stamped into the metal rather than raised in relief. Dating by Visual Clues
Pre-1892: These chairs generally lack a hydraulic lift system (the lever won't pump them up) and rely only on mechanical recline.
1892 Onward: The introduction of the patented hydraulic lift system revolutionized the brand. Most chairs with a working pump are post-1892.
Materials: Victorian-era chairs (late 1800s) often feature ornate wood carvings (oak/walnut). 1920s chairs shifted to heavy porcelain, while 1950s models utilized more chrome and vinyl.

Because serial lists are inexact, look for these physical clues mentioned in guides from LoveToKnow and JustAnswer:
Hydraulics: If the chair has a working hydraulic lift, it was likely manufactured after Ernest Koken's 1892 patent.
Materials: Wood-heavy frames (Oak/Walnut) with ornate carvings usually date to the late 1800s or early 1900s. Porcelain-coated cast iron became standard for the 1920s-1940s "white" look.
One-Lever Mechanism: Introduced around 1900, this allowed the barber to control all chair functions with a single lever.
