About this product
Quadrant Soft Modular Sofa — Sustainable, Flexible Seating for Workplaces & Learning Environments
Originally inspired by the relaxed comfort of baggy jeans, the Quadrant Soft Sofa is Koskela’s iconic modular seating solution for corporate workplaces, universities, creative environments and homes. Designed and manufacture in Australia since 2009, it brings together long-lasting comfort, reconfigurable design, and creative expression.
Each module is crafted from dense yet extremely lightweight foam, making it easy to move, reconfigure, and adapt to evolving needs — no tools or heavy lifting required. Whether you’re refreshing a breakout area, creating a quiet reading nook, or rethinking an entire floor plan, Quadrant is built for agile spaces.
What sets Quadrant apart is its creative flexibility — mix and match fabrics across modules to create a bespoke look tailored to your interior scheme. Over time, you can easily swap out covers to refresh the aesthetic or adapt to changing seasons, with the option to purchase extra covers for summer and winter styling. This reduces waste and extends the product’s life while offering practical, low-cost ways to rejuvenate your space.
Covers are removable and dry-cleanable, making maintenance simple. And thanks to Koskela’s repair and renew program, parts can be replaced individually, minimising environmental impact and keeping your sofa in use for longer.
Leather cross-stitches and embossed handles provide signature design touches that speak to quality and craft.
