Folding chairs have a reputation problem. For most of us, they conjure up images of bare banquet halls, plastic legs scraping across gymnasium floors, or that wobbly stack in the back of a relative’s garage. They are furniture by necessity, not by choice. So when a design studio manages to make one that you’d genuinely want to keep out in your living room, it’s worth paying attention.

That’s exactly what PLANK and designers Matteo Thun and Benedetto Fasciana have done with the Theo folding chair, quietly one of the most interesting pieces to come out of Salone del Mobile Milano 2026 this past April. Not because it does something shocking or avant-garde, but because it does something much harder: it makes the utilitarian feel considered.

Designers: Matteo Thun and Benedetto Fasciana for PLANK

PLANK has been at this since 1953, and that legacy shows in how Theo is built. The frame is solid oak, which already puts it in a different category from the folding chairs most of us know. The seat and backrest are made from molded plywood, shaped with a gentle curve that reads as both ergonomic and graceful. The folding mechanism uses natural or black oxidized stainless steel, and it integrates into the structure so cleanly that you almost forget it’s a functional joint and not just a detail. The chair opens and closes without any of the awkward fuss you’d expect. It simply works, and it looks good doing it.

I’ve always believed that the real test of a design isn’t how it performs in ideal conditions but how well it disappears into a life that isn’t perfectly curated. Most furniture is designed with a room in mind. Theo was designed with reality in mind. It’s built for contract spaces, meaning restaurants, event venues, conference rooms, places where chairs get used hard and stored constantly. But the visual language doesn’t give that away. If you didn’t know, you’d assume it was a permanent resident of whatever room it happened to be in.

The finish options only add to that versatility. You can get Theo in natural or stained oak veneer, or in a matte open-pore lacquer in Walnut, Brown Red, Olive Green, or Black. Each feels deliberate rather than decorative. The seat cushion options go even further: a 100% wool Moessmer Dolo Loden fabric in four colors, or Dani Florida leather in 96 colors. That last number sounds excessive until you realize it’s actually kind of brilliant. It’s the difference between a chair that fits into a space and one that was made for it.

There’s also a companion Transport Trolley that was developed alongside Theo, designed to stack and move up to eight chairs at once. It’s a practical addition that rounds out the system nicely, especially for the hospitality and event sectors where Theo will likely see the most use. But even outside those contexts, the Trolley signals something important about how PLANK approaches design: everything has to work together, not just look good in isolation.

Matteo Thun is no stranger to pieces that carry a quiet authority. He’s had a long career built on the idea that good design should be sustainable, functional, and beautiful in equal measure, and Theo reflects all three. The fact that PLANK uses solid wood and always-recyclable materials isn’t incidental. It’s the whole point. Longevity is designed in from the start, not marketed as an afterthought.

What makes Theo genuinely compelling is how little it asks of you. It doesn’t demand a particular aesthetic or a specially styled room. It doesn’t need to be the centerpiece. It can be stacked in a closet and brought out for dinner parties, or it can live at the head of a table year-round, and it holds up either way. That’s a rare quality in furniture, and it’s even rarer in a folding chair.

The best designs tend to solve problems you didn’t realize had elegant solutions. Theo is a folding chair that looks like it was never trying to be anything else, and that, more than any other detail, is the thing that makes it worth talking about.
