Ploum (small sofa low-back version)

Ronan et Erwan Bouroullec

The Ploum Sofa small low-back version, designed by Ronan Bouroullec and Erwan Bouroullec for Ligne Roset, is the result of an extensive research project focused on creating an entirely new level of comfort in contemporary seating.

The concept of the Ploum sofa is based on an innovative combination of two materials: a highly stretchable upholstery fabric and ultra-soft multi-density foam. This unique pairing allows the sofa to adapt naturally to the body, creating an exceptionally comfortable and flexible seating experience. The generous proportions and organic form encourage a variety of relaxed seating positions, whether used alone or shared.

Following the designers’ vision, the sofa features a subtle asymmetrical construction: one side of the backrest is slightly higher than the other, while one side of the seat is slightly deeper. This asymmetry enhances the sense of freedom and movement while maintaining visual harmony.

The slightly inward-angled seat encourages closer seating positions, fostering interaction and conversation between users. With its extremely soft contact and free-flowing shape, the Ploum sofa feels like a true nest of comfort, where the same enveloping softness can be experienced across the entire surface of the seat, including the armrests.

Available in a selection of specially developed stretch fabrics, the Ploum sofa integrates beautifully into contemporary interiors while adding a sculptural and welcoming presence to the living space.

Sisu is an official Ligne Roset retailer in Brussels, conveniently located for clients from Brussels, Walloon Brabant and Flemish Brabant, including Zaventem, Kraainem, Tervuren and Waterloo. The Ploum sofa can be discovered in our showroom or ordered online with delivery throughout Belgium and Luxembourg.
