Ligne Roset Ploum Large High Back Sofa: Asymmetrical Lounge Created by the Bouroullec Brothers' Research on 'Seating Freedom'

Curves That the Body Responds to First

Ploum Large sofa high back is closer to a lounge that expands the patterns of sitting rather than serving as a 'central living room furniture.' Rather than correcting posture by adding more cushions, the sofa itself is designed to absorb posture. The high back version increases the area of support extending to the shoulders and head, emphasizing extended relaxation.

Ligne Roset's Manufacturing Context

Ligne Roset is known as a brand that started from a 19th-century woodworking workshop and has continuously emphasized both its manufacturing base in France and its collaborative designer system to this day. In particular, it is characterized by relatively detailed disclosure of production facilities and handcrafting processes through its own channels. The brand's 'Made in France' manufacturing context can be found in History, Made in France.

Ploum's Definition of 'Comfort'

Ploum is introduced as a sofa where Ronan & Erwan Bouroullec took 'research on comfort' as their starting point. The brand highlights the combination of elastic covers and very soft foam as the key, and focuses on expanding the spectrum of movements such as sitting, leaning, lounging, and semi-recumbent positions. The official description and designer information for this product line can be found at PLOUM, and designer background at Erwan Bouroullec.

Asymmetry Creating Conversation

The particularly interesting point about the Ploum Large series is that it deliberately avoids 'perfect symmetry of form.' According to the official introduction, the large settee has a higher right backrest, a deeper right seat, and the rear zipper is also slightly off-center. The seating is premised on subtle angles that face toward each other, so when multiple people sit, their body directions naturally converge inward. Early introductory articles mention that this sofa was unveiled at imm cologne and Maison&Objet, emphasizing the impression of a 'croissant shape' that wraps around the body (designboom). To see the product in more detail, it's faster to check the configuration and images together at the product purchase page.

Impression After Installation: Terracotta Tone Makes Curves More Distinct

According to buyer reviews, this sofa was delivered on December 3, 2025, and a warm terracotta fabric was selected. What is impressive is that when the 'enveloping surface' created by the high back and deep seating meets the color tone, the bulk appears rather organized. Despite being a large sofa, the backrest line varies in height so that the eye doesn't focus on just one side.

What Spaces Does It Suit?

Ploum Large sofa high back is not a sofa for 'sitting properly,' but rather one that accommodates the actual changes in posture that occur repeatedly at home. It works in living rooms where you look in one direction like watching TV, but its advantages stand out in spaces with longer dwell times such as conversation-focused living rooms or bedroom lounges. When placed with space that reads the asymmetry and curves (passage width) rather than pushed flush against the wall, the design's intention becomes clear.
