Cassette Sofa – Established and Sons
Designed by Ronan and Erwan Bouroullec. Bringing together contrasting materials and a simple form, Ronan and Erwan Bouroullec have created a statement sofa that offers solidity, versatility, comfort and contemporary style, with a slim steel frame and deep upholstery.

For Established & Sons’ 2018 collection, launching at Milan design week, the brothers have created Cassette, a sofa that has been four years in the making. It is an evolution of a basic principle that was explored with one of those earlier collaborations, the Quilt sofa from 2009. Now a 21st-century design classic, the honeycomb-upholstered Quilt grew out of the idea of creating a seat that was as welcoming as a duvet or a blanket. At first glance, the relationship between Cassette and Quilt might not be obvious. Where Quilt has curves and is covered in plush, bouncy upholstery, Cassette has straight lines, with an entirely exposed structure and deep, rectangular cushions. But it offers a different kind of flexibility – Ronan suggests taking the generous cushions off the sofa and arranging them on the floor to create a bed – and there is no compromise on comfort.
