When it comes to furniture design, lightness is usually a metaphor. For Isomi’s Knit One Chair, designed by Paul Crofts, it’s a material reality. Gone are the layers of foam and heavy upholstery. In their place, a 3D-knitted skin is all that’s needed to balance comfort, structure, and sustainability in equal measure.
Removing the materials that traditionally add plushness might sound counterintuitive, but Knit One proves that comfort doesn’t rely on excess – it comes from smart design. “With the Knit One chair, we wanted to break away from wasteful, resource-heavy upholstery,” shares Paul Crofts, Design Director at Isomi. “The frame simply bolts together on site, while the knit sleeve, woven with mono-filament structural fibers, drops into place –minimal waste, maximum impact.” It’s proof that comfort doesn’t depend on layers, but on the integrity of materials and the innovation behind them.
The chair’s knitted sleeve is made from Camira’s SEAQUAL® Collection, a textile crafted from post-consumer marine plastic waste – up to 35 recycled bottles per meter. The material is shaped using advanced 3D knitting technology, which eliminates excess fabric waste and ensures precise construction. Fully recyclable and replaceable, the sleeve extends the chair’s lifespan while removing the need for adhesives or foam. A lightweight metal frame supports the knit structure and allows the chair to be shipped flat-pack, further reducing the overall carbon footprint and making local assembly effortless – a rarity when it comes to large-scale furniture.
The Knit One Chair is part of a modular seating system that includes a lounge chair, straight ottoman-style module, angled module, and a solid wood side table. Together, they form a flexible arrangement that adapts to any space, from open-plan offices to relaxed residential interiors. Each piece is fully reversible, allowing endless configurations that shift from solo lounging to group seating with ease, reflecting the same thoughtful versatility that defines Isomi’s approach to design.
Sustainable design can take many forms. Sometimes it requires redefining what is “excess,” removing it entirely, and reimagining how we can still experience comfort through simplicity. The Knit One Chair embodies a less is more philosophy, where designing with minimal materiality creates more space – for innovation, longevity, and a lighter impact on the planet.
