You’ve seen them in the corner of a dusty "shabby chic" boutique or sitting under a pile of lace at an estate sale. Usually, they’re chipped. Often, they’re painted a shade of mint green or hospital white that hasn't been popular since the Truman administration. They look cool, right? But honestly, an antique metal high chair is a complicated beast. It’s not just a piece of furniture; it’s a heavy, clunky, often dangerous slice of industrial history that tells us a lot about how we used to treat babies—and how much we valued "sanitary" surfaces over actual comfort.
People buy these today for the aesthetic. They want that farmhouse vibe. But if you're planning on putting a real human infant in one, you need to pump the brakes. There's a massive difference between a mid-century Chrome-craft and a Victorian wrought iron piece. One is a vintage décor win. The other is a literal "pincer-hazard" waiting to happen.
Why the Obsession with Metal Anyway?
Back in the early 1900s, mothers were terrified of germs. And rightfully so. Before the widespread use of antibiotics, a simple case of "summer diarrhea" or scarlet fever could be a death sentence for a child. Wood was seen as porous. Wood was "dirty." It had cracks where crumbs and bacteria could hide.
Enter the metal era.
Companies like Koken Companies in St. Louis or the Cosco brand (which basically ruled the 1940s and 50s) started churning out steel and chrome models. The logic was simple: you can scrub metal with boiling water and lye. It’s sterile. It’s "modern." By the time we hit the 1950s, the chrome-and-vinyl high chair became the suburban standard. These things were built like tanks. You could drop them off a roof and they’d probably just dent the pavement.
But here’s the thing. They weren't exactly "cozy."
Imagine sitting on cold steel in a diaper. Not great.
The Safety Reality Check
We have to talk about the elephant in the room: lead paint and finger-pinching hinges. If you find an antique metal high chair with its original finish from before 1978, it almost certainly contains lead.

Lead is sweet. Kids lick things. You see the problem.
Beyond the toxicity, the engineering was... let's say "optimistic." Modern high chairs have five-point harnesses and crotch posts to keep babies from sliding out. A 1930s metal chair? It usually has a single leather strap that’s probably rotted away, or a metal tray that slides on a track with enough force to take off a fingertip. I’ve seen some models where the tray "locks" via a spring mechanism that is basically a bear trap for toddlers.
If you're looking at a Simmons or a Thonet metal piece, check the joints. Rust isn't just an "aesthetic patina." It’s a structural failure. If the tubular steel has rusted from the inside out—which happens if they were stored in damp garages—the legs can buckle without warning.
Spotting the Real Deals (Value and Identification)
Collectors generally look for three specific types of metal chairs.
First, there’s the Victorian Wrought Iron style. These are rare and usually incredibly ornate. They weren't mass-produced in the way later models were. Often, they featured scrollwork and looked more like garden furniture. They are heavy. Extremely heavy. If you find one with the original porcelain or enamel tray intact, you’re looking at a piece that can fetch $300 to $500 at a high-end antique mall.
Then you have the Art Deco / Machine Age chairs. Think streamlined steel. Tubular frames. Brands like Loyal Knight or Storkline dominated this era. They look like they belong in a 1930s diner. The value here is in the "look." Designers like Gilbert Rohde influenced this era, focusing on the beauty of the material itself.
Finally, there’s the Mid-Century Chrome. This is the Cosco era. These are the ones your grandma had. They usually have a flip-over tray or a tray that slides on side rails. They often came with bright red or yellow vinyl padding. While these are the most common, they are also the most functional for modern repurposing. A mint-condition 1950s Cosco chair with original "cracked ice" vinyl can still pull $150.

How to Refurbish Without Ruining the History
If you've picked up a rusty antique metal high chair at a garage sale for twenty bucks, don't just hit it with a can of Krylon and call it a day.
- Test for Lead. Get a 3M LeadCheck swab. They’re cheap. If it turns red, you need to rethink your DIY strategy. Sanding lead paint releases dust into your lungs and your home. If it's lead-positive, your best bet is professional powder coating or a chemical strip performed by someone with the right gear.
- The Magnet Test. Is it actually steel? Most are. But some "metal" chairs from the 70s were actually aluminum or cheap alloys. A magnet will stick to steel. If it doesn't stick, you might have an aluminum piece, which won't rust but can be much harder to weld if it’s broken.
- The Tray Mechanism. Most old trays used a "squeeze and slide" or a "gravity drop" latch. Over 70 years, these springs get tired. You can usually find replacement springs at a hardware store, but don't force a stuck tray. You'll bend the rail, and once a metal rail is kinked, it never slides smoothly again. Basically ever.
Creative Repurposing: Don't Put the Baby in It
Since most antique metal chairs don't meet modern ASTM International safety standards (specifically F404 for high chairs), what do you do with them?
Plants.
Seriously. A white enamel high chair with a cascading fern where the baby used to sit is a classic interior design move for a reason. It adds height to a room. It provides a "pedestal" feel without being a literal pedestal.
I’ve also seen people use them as eccentric "entryway catch-alls." Put a bowl on the tray for your keys. It’s a conversation starter. It’s weird. It works.
Another popular move is the "garden focal point." Since they're metal, they can handle the elements better than wood. Let a clematis vine wrap around those Art Deco tubular legs. In five years, it’ll look like a piece of living sculpture.
What the "Experts" Get Wrong
A lot of antique dealers will tell you that "all metal chairs are more durable than wood."

That’s a lie.
Steel fatigues. Welds snap. A wooden chair from 1890 held together with hide glue is often easier to repair than a 1940s steel chair with a cracked weld. Unless you know how to TIG weld, a broken metal frame is basically scrap.
Also, watch out for the "reproduction" trap. In the late 1990s, there was a surge of companies making "vintage-look" metal high chairs. They look old, but the metal is thinner, and the screws are modern Phillips heads instead of the flat-head screws you’d see on a true antique. If the metal feels light or "tinny," it’s probably a modern knock-off.
Market Trends for 2026
The market for the antique metal high chair is shifting. We’re moving away from the "perfectly restored" look. People want the "as-found" condition—as long as it isn't literally falling apart. The industrial aesthetic is still holding strong in urban loft designs.
If you’re selling, don't over-restore. Clean the grease off. Remove the loose rust with a wire brush. Apply a coat of clear wax (like Minwax or Briwax) to seal the original paint and stop further oxidation. This preserves the "story" of the chair while making it clean enough to touch.
Practical Next Steps for Owners
- Audit the hardware: Replace any rusted-out bolts with "distressed" new hardware if the original is stripped. It keeps the piece stable.
- Check the feet: Most of these chairs had rubber or wooden "glides" on the bottom. If they're missing, the metal legs will scratch your floors like a diamond. You can find "retro" replacement feet online that fit the standard 1-inch or 7/8-inch tubing.
- Identify the maker: Look under the footrest or on the back of the main seat frame for a stamped logo. Finding a "Made in Occupied Japan" stamp or a specific US patent number can triple the value of the chair to the right collector.
- Safety first: If you absolutely insist on using it for a child, it must be retrofitted with a modern T-strap harness. No exceptions. You'll have to drill through the metal to anchor it. It ruins the collector value, but it saves the baby. Honestly, just use it for a plant. It’s safer and looks better anyway.
Metal high chairs are a window into a time when we thought we could "engineer" away the messiness of childhood. They are cold, loud, and heavy. But they have a soul that a plastic Graco just can't match. Respect the rust, check the welds, and keep the lead away from the kids.
