Vintage Koken barber chairs are identifiable by serial numbers typically stamped on the underside of the seat frame, wood base, or metal frame. While exact factory records are scarce, collectors use sequential production ranges to estimate age. Koken Serial Number Aging Guide (Approximate)
Manufacturing years are estimated based on these sequential ranges: 1 – 999: c. 1881 (Earliest reclining models).
1,000 – 9,999: c. 1885 – 1888 (Introduction of swiveling features).
10,000 – 25,000: c. 1895 – 1905 (First hydraulic models). 25,001 – 50,000: c. 1906 – 1915. 50,001 – 85,000: c. 1916 – 1925.
85,001 – 125,000: c. 1926 – 1935 (Art Deco styling peak). 125,001 – 175,000: c. 1936 – 1945.
175,001 – 225,000: c. 1946 – 1955 (Post-war production). 225,001+: c. 1956 – 1960s (Late-stage production). Key Identifying Features by Era
Beyond serial numbers, specific mechanical and design shifts help verify the age of your chair: Key Features Late 1800s
Wood frames (oak or walnut), elaborate carvings, manual reclining only (pre-1892). Early 1900s
Introduction of the hydraulic lift and "joystick" side lever for control. 1920s–1930s
Transition to porcelain and chrome finishes with Art Deco aesthetic. 1940s–1950s
Simpler mid-century designs, often with less ornate metalwork and more vinyl upholstery. Historical Context Determine Koken Chair Age by Serial Number - Expert Guide
While there is no single, publicly accessible master "serial number list" for vintage Koken barber chairs today—as many factory records from the original St. Louis-based Koken Barbers Supply Company were lost when it went out of business in the 1950s—serial numbers remain the most reliable way to estimate a chair's production era when used alongside stylistic cues. Collectors typically cross-reference these numbers with known patent years and historical sales records to date their pieces. How to Find Your Koken Serial Number
Before you can date your chair, you must locate the stamped identifier. Koken typically placed these numbers in consistent locations:
Underside of the Seat Frame: This is the most common location. You may need to remove the seat cushion or flip the chair carefully to find a stamped number on the wood frame or the metal base plate.
Main Iron Base Casting: Many models have numbers molded directly into the cast iron of the base or near the hydraulic pump.
Metal Identification Tags: Some later models (circa 1920s–1930s) featured a small metal tag riveted to the frame under the seat or on the back of the footrest.
Note on Casting Numbers: Be careful not to confuse casting numbers (e.g., "52CB") with serial numbers. Casting numbers are part identifiers used during manufacturing and are shared by all chairs of that specific model, whereas serial numbers are unique sequential identifiers.
