The Vitra Unix — versatile Swiss design that stacks, flexes, and adapts. Its signature cantilever frame provides a gentle bouncing flex that encourages active sitting, while the breathable mesh back keeps you cool. Stackable for compact storage, available with standard glides or smooth-rolling casters. Professionally refurbished, 6-month warranty.
Key Features
Cantilever Frame — Gentle Flex
The Unix's cantilever design is its defining feature. Unlike rigid four-leg chairs, the continuous curved frame provides a subtle, spring-like flex as you shift your weight. This micro-movement encourages active sitting — engaging your core muscles and reducing static pressure on your spine throughout long meetings and conferences.
Breathable Mesh Back
Tensioned diamond-pattern mesh backrest provides ventilation and light ergonomic support. Cool, breathable, and comfortable for hours of conference or training room use.
Stackable — Store With Ease
Designed for multi-purpose spaces: stack the Unix chairs compactly when not in use, deploy them in minutes when needed. Perfect for conference rooms, training venues, event halls, and visitor seating that needs to disappear between uses.
Swiss Design Heritage
Vitra — the legendary Swiss furniture maker behind the Eames, George Nelson, and Jean Prouvé collections. The Unix reflects their commitment to clean lines, functional design, and enduring build quality. A chair that looks as refined in a corporate boardroom as it does in a creative studio.

FAQ
What is a cantilever chair?
A cantilever chair has no back legs — the frame curves continuously from the front legs, under the seat, and up to form the backrest. This creates a gentle flex that moves with your body, unlike rigid four-leg chairs. It's a hallmark of mid-century modern design and particularly comfortable for meetings and conferences.
Can I stack these chairs?
Yes — the Unix is designed to stack up to 6 chairs high for compact storage. The standard glides version stacks cleanly. The wheels version is best for individual mobility rather than stacking.
What is the condition of these chairs?
Professionally refurbished — thoroughly cleaned, frame inspected, mesh checked, and functionally tested. The cantilever frame is extremely durable and shows minimal wear even with years of use.
