Circular Furniture Design: The Bascule Chair

Circular furniture design offers a more sustainable approach to creating comfortable, beautiful and long-lasting interiors. The Bascule lounge chair, designed by Studio Πfor Vitra, illustrates this approach through its sculptural form, removable upholstery and replaceable components. By combining comfort with repairability, the chair encourages architects and interior designers to consider how furniture can remain useful for longer.

The Bascule lounge chair, designed by Berlin-based Studio Πfor Vitra, offers an interesting example of this shift. Combining a relaxed, sculptural appearance with an innovative reclining mechanism, removable upholstery and replaceable components, the chair demonstrates how comfort and circular design can work together.

Presented at 3daysofdesign in Copenhagen in 2026, Bascule reflects a wider movement in contemporary furniture design: moving beyond the appearance of sustainability towards products whose construction supports longer use and more responsible material management.

For Interi(o)tecture, Bascule provides a starting point for exploring a fundamental question: Can the next generation of furniture be both desirable and designed for a more circular future?

What Is Circular Furniture Design?

Circular furniture design challenges the traditional model of producing, purchasing and eventually discarding furniture. Instead of treating a chair or table as a disposable product with a predetermined lifespan, circular design considers what happens throughout its entire life cycle.

This approach begins during the design process. Designers consider the origin of materials, how individual components are assembled, whether parts can be repaired or replaced, and how materials might be recovered when a product is no longer needed.

In upholstered furniture, these questions are particularly important. Conventional construction can involve permanently bonded materials, glued foam and covers that are difficult to remove. When different materials cannot be separated easily, repairing or recycling a single component may become unnecessarily complicated.

Circular furniture design offers an alternative. Mechanical connections, accessible components, replaceable upholstery and carefully selected materials can help furniture remain useful for longer while making maintenance and end-of-life processing more manageable.

However, circularity is not determined by a single feature. Material sourcing, manufacturing, transportation, durability, repair services and eventual recovery all influence a product’s overall environmental performance. A removable cover is a useful starting point, but the broader system matters too.

Bascule: Circular Furniture Design Meets Comfort

Designed by Lisa Ertel and Anne-Sophie Oberkrome of Studio Œ, the Bascule lounge chair brings together an expressive upholstered form and a construction intended to support maintenance and repair.

The chair’s defining visual feature is its relaxed textile covering. Rather than stretching the fabric tightly across a rigid structure, the designers allow it to wrap around the chair like a tailored jacket. This approach draws on techniques from fashion and tailoring, translating the familiar qualities of clothing into an upholstered furniture design.

Its appearance is soft and inviting, while its integrated mechanism allows the chair to move from an upright sitting position towards an almost horizontal reclining position. The mechanism responds to the user’s weight, combining functional movement with a calm, sculptural presence.

Bascule is available in highback and lowback versions, with different base options. These variations make it adaptable to different interior settings, from residential living rooms to hospitality spaces and workplace lounges.

Yet the chair’s most significant contribution to the discussion of sustainable furniture lies beneath its appearance.

According to Vitra and the German Design Council, Bascule avoids adhesives in its construction and uses separable components that can be repaired or replaced. Its cover can be removed for cleaning or replacement, while its cushions use recycled fibres or V-Foam, a recyclable polyurethane foam developed by Vitra and BASF.

These choices illustrate how circular thinking can influence the relationship between a product’s appearance, assembly and long-term use.

Why Repairability Matters in Interior Design

For sustainable interiors, circular furniture design can help reduce unnecessary replacement by making maintenance and component renewal more practical.

Furniture frequently remains in service within buildings long after individual components begin to wear. Upholstery becomes stained or damaged, mechanisms require attention, and finishes deteriorate through everyday use.

When a product is difficult to repair, a relatively small problem can lead to the replacement of the entire object. This creates additional demand for materials and manufacturing while sending usable components into waste streams.

A chair designed for repair offers another possibility. If its upholstery can be removed and replaced, the owner may be able to refresh its appearance without purchasing an entirely new chair. If a mechanism or other component can be exchanged, the rest of the product may continue to serve its original purpose. For interior designers, this has practical implications.

In residential projects, repairable furniture can support longer-term ownership and allow interiors to evolve without unnecessary replacement. In hotels, offices and hospitality environments, where seating experiences frequent use, access to maintenance and replacement parts can be particularly valuable.

For architects working on projects with long service lives, the ability to maintain interior components can also complement broader strategies for reducing material consumption and extending the useful life of buildings.

The important consideration is not simply whether a product can theoretically be repaired. Designers and clients should also ask whether replacement parts are available, whether repairs are practical, and whether the manufacturer provides reliable after-sales support.

Circular Materials and Responsible Furniture Design

Recycled materials are an important part of the circular economy, but they do not tell the whole story.

Bascule demonstrates why designers should consider material composition alongside construction. Its use of recycled fibres and recyclable foam is accompanied by an approach that avoids permanently bonding the chair’s components together.

This distinction matters because a product made partly from recycled materials may still be difficult to repair or recover at the end of its life. Conversely, a product designed for disassembly can make it easier to separate materials for different maintenance or recovery pathways.

For architects and interior designers, material specifications should therefore address several questions:
Where do the materials come from, and what proportion is recycled or renewable?
Can upholstery, padding, frames and mechanisms be separated?
Are individual components available as replacement parts?
What maintenance is required to preserve the product?
Can materials be recovered through realistic collection and recycling systems at the end of use?

These questions encourage a more complete assessment of furniture sustainability. They also help avoid treating individual environmental claims as proof that a product is sustainable in every respect.

The next step is to consider how a piece of furniture performs within its actual context: how intensively it will be used, how easily it can be maintained, and whether it will remain desirable and functional over time.

Designing Circular Furniture for Longevity

One of the challenges facing sustainable furniture design is the perception that environmental responsibility requires compromising visual quality or comfort.

Bascule challenges that assumption. Its loosely draped upholstery gives it a distinctive character, while its reclining mechanism prioritises comfort. The chair’s circular design features are integrated into its construction rather than expressed through a visibly technical or industrial aesthetic.

This is an important lesson for contemporary interiors. Sustainable design does not have to be visually austere, nor must it rely exclusively on natural colours, unfinished materials or minimalist forms.

Instead, designers can integrate repairability, material transparency and adaptability into products that remain emotionally appealing. A piece of furniture that people enjoy using and want to retain may have a better opportunity for a long service life than an object that is quickly discarded because it no longer meets their needs.

Longevity nevertheless depends on more than appearance. Structural quality, comfort, maintenance, availability of parts and changing user requirements all contribute to whether furniture remains in use.

For this reason, circular furniture design should be understood as a combination of technical decisions and human experience.

What Interior Designers Can Learn from Circular Furniture Design

The Bascule lounge chair offers several useful principles for professionals specifying furniture in sustainable interiors.

1. Prioritise repairability from the beginning. Ask manufacturers how components are connected and whether damaged parts can be replaced independently.
2. Specify removable and replaceable upholstery. Where appropriate, choose furniture that can be cleaned, refreshed or reupholstered without replacing its entire structure.
3. Evaluate material systems, not isolated claims. Recycled content is valuable, but designers should also investigate durability, separability and realistic end-of-life options.
4. Consider the full service life. Purchase price alone does not capture the value of a product that can remain functional through repeated maintenance and changing interior requirements.
5. Request evidence. Product documentation, material declarations, repair instructions, spare-parts information and relevant environmental assessments can support better-informed specifications.
6. Match products to their intended use. A lounge chair selected for a private residence may face different demands from seating in a hotel lobby or shared workspace. Durability and maintenance requirements should reflect the actual setting.

These principles can guide furniture selection well beyond lounge chairs. They are relevant to dining chairs, office seating, sofas, modular systems and other interior products that combine multiple materials and components.

The Future of Circular Furniture Design

As expectations evolve, circular furniture design will increasingly depend on combining lasting aesthetic appeal with accessible repairs and responsible material management.

The Bascule lounge chair is one example of a wider movement towards furniture that considers its life beyond the moment of purchase. Across contemporary design, manufacturers and independent studios are exploring separable construction, bio-based materials, recycled resources and alternative production methods.

The German Design Council’s report, Circular Approaches in Copenhagen, documents this broader range of approaches showcased at 3daysofdesign in 2026, including furniture designed for disassembly and materials developed from waste streams.

Together, these examples suggest that the future of sustainable interiors will depend on more than choosing products labelled as environmentally friendly. It will require thoughtful decisions about how objects are made, maintained, adapted and eventually recovered.

For architects, interior designers and environmentally conscious consumers, the essential question is therefore changing. Rather than asking only what a piece of furniture looks like or what materials it contains, we should also ask how long it can remain useful and what happens when its individual components need attention.

Bascule offers a compelling case study in that shift. By bringing together comfort, sculptural form and repair-oriented construction, it demonstrates how circular principles can become part of the design experience itself.

At Interi(o)tecture, we believe that the future of interiors depends on looking beyond the finished object. Furniture that is designed to last, maintained with care and supported by responsible material choices can contribute to spaces that are not only beautiful and functional, but also more thoughtful about the resources they consume.

Effective circular furniture design considers the entire product lifecycle, from material sourcing and assembly to repair, reuse and eventual recovery. The next generation of sustainable seating will not be defined by appearance alone. It will be defined by the ability to combine design quality with a longer, more responsible life.
