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

Curves That Your Body Reacts to First

The Ploum Large sofa high back is less of a 'central living room furniture' and more of a lounge that expands the patterns of sitting behavior. Rather than correcting posture by adding more cushions, the sofa itself is designed to absorb posture. The high back version increases the support area for shoulders and head, placing emphasis on extended rest.

Ligne Roset's Manufacturing Context

Ligne Roset is known as a brand that has evolved from a 19th-century woodworking workshop and continues to emphasize both its manufacturing base in France and its collaborative designer system to this day. In particular, it is characterized by relatively detailed disclosures about production sites and handcrafted 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 having been developed by Ronan & Erwan Bouroullec with 'research on comfort' as its starting point. The brand highlights the combination of elastic covering and very soft foam as its key feature, focusing on expanding the spectrum of movements such as sitting, leaning, slouching, and semi-reclining. The official description and designer information for this product line can be found at PLOUM, and designer background at Erwan Bouroullec.

Asymmetry Creates Conversation

A particularly interesting point about the Ploum Large series is that it deliberately avoids 'perfect symmetry of form.' According to the official description, the large settee has a higher right backrest, a deeper right seat, and the rear zipper is also slightly off-center. The seating assumes subtle angles that face each other, so when multiple people sit, their body direction naturally gathers inward. Early introductory articles mention that this sofa was unveiled at imm cologne and Maison&Objet, emphasizing the impression of a 'croissant-shaped' form that wraps the body (designboom). For a closer look at the product, it's helpful to check the composition and images together at the product retailer.

First Impression After Installation: Terracotta Tone Makes Curves More Distinct

According to buyer reviews, this sofa was delivered on December 3, 2025, and the purchaser chose a warm terracotta fabric. What is striking is that when the 'body-wrapping' surface created by the high back and deep seating meets the color tone, the bulk appears more organized. Despite being a large sofa, the varying heights of the backrest line prevent the eye from being drawn in only one direction.

What Spaces Does It Suit?

The Ploum Large sofa high back is not a sofa for 'sitting properly,' but rather one that accommodates the actual postural changes that occur repeatedly at home. It suits living rooms where you look in one direction like TV watching, but its advantages are particularly pronounced in conversation-centered living rooms or bedroom lounges where people spend extended time. When placed with adequate space (traffic width) to read the asymmetry and curves rather than pushing it flush against a wall, the design's intention becomes clear.
