Australian made sustainable comfort for everyday homes.

Originally inspired by the relaxed comfort of baggy jeans, the Quadrant Soft Sofa is Koskela’s most loved and versatile lounge system — perfect for homeowners seeking contemporary style, lasting comfort, and sustainable design.

Designed and manufactured 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 & 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.

The Quadrant Soft Sofa range can be mixed and matched with the Curved Quadrant range
