Pre-loved Quadrant Soft Single Sofa - High Seat - 450Hmm

The perfect modular sofa for commercial environments, the Quadrant Soft combines flexibility, comfort and durability for workplaces, education spaces and collaborative environments. These pre-loved Quadrant Soft sofas have been carefully sourced from commercial fit-outs and are presented in excellent condition, with no obvious flaws.

Each module is sold individually and is crafted from dense yet lightweight foam, making it easy to move, reconfigure and adapt as your workplace evolves. Whether creating breakout areas, quiet zones, waiting spaces or collaborative settings, the modular design allows you to reconfigure your layout as your needs change.

As part of our Rehome program, every pre-loved sofa has been professionally cleaned, rigorously quality checked and is ready for its next workspace.

Upholstered in a recycled wool fabric, the textile appears solid from a distance while revealing subtle colour variation and texture up close. Its tight, refined weave and melange yarns create depth, durability and timeless appeal.

This is a genuine pre-loved Koskela piece, inspected and resold to extend its life. It includes our 7-Year Rehome Warranty together with access to our Repair & Renew program.
