Most furniture doesn’t have a backstory worth telling. The Maniac Chair does. It looks, from across the room, like it wandered out of a 1950s Danish design studio — until you get close enough to realize it’s built from the same bloodline as a $2.35 million hypercar.
Oilstainlab is the California-based studio founded by Ukrainian-born twins Iliya and Nikita Bridan — high school dropouts trained in Italy and California, responsible in their previous lives for 6.5 million street cars. In 2018, they started Oilstainlab with a single promise: never to be sane. The result was the HF-11, a limited-production hypercar of which only 25 will ever exist. The Maniac Chair is the furniture-world extension of that same obsession, sold through House Dé Stains, Oilstainlab’s lifestyle brand.
Designer: Oilstainlab
The chair’s shell is built on a CNC-machined aluminum frame wrapped in a hand-laid carbon fiber shell. That detail matters. Hand-laid carbon fiber isn’t a production shortcut — it’s the language of motorsport, of race seats and monocoques shaped around bodies doing 200 mph. Here, it’s shaped around a body doing nothing more than sitting. That deliberate mismatch is the whole point. The midcentury silhouette is familiar enough to read as furniture; the material is foreign enough to make you question what you’re actually looking at.
The name traces back directly to the HF-11, which Oilstainlab offered in an exclusive “Maniac” package for 11 of its 25 cars. The chair carries that identity forward — it’s not merchandise, it’s an extension of a design philosophy that treats excess and restraint as two sides of the same surface. The carbon fiber reads as raw and technical; the form reads as warm and considered. Neither cancels the other out.
What Oilstainlab has done here is something furniture designers rarely attempt, and automotive designers rarely bother with: they’ve made a chair that has genuine provenance. It isn’t inspired by cars in the way that means “we added some aggressive lines.” It shares DNA with an actual race seat.
The prep process before upholstery even echoes motorsport fabrication. For a studio built on the idea that sanity is optional, the Maniac Chair is a surprisingly coherent object. It knows exactly what it is — a piece of furniture for people who want to sit inside a design argument — and it doesn’t flinch.
