6trees is a German design and manufacturing company that specializes in wooden furniture and lifestyle accessories. Founded in 2010 by Hans Jansen and Lena Meyer, the firm established a reputation for combining minimalist aesthetics with environmentally responsible production practices. Each product is typically crafted from a single tree, a principle that underpins the brand’s commitment to traceability, reduced waste, and the celebration of natural grain patterns. Since its inception, 6trees has expanded its catalog to include chairs, tables, desks, lamps, and a range of household items, while maintaining a focus on clean lines, functional form, and durable construction.
History and Background
Founding and Early Development
The origins of 6trees trace back to the early 2010s when Jansen, a former industrial designer, and Meyer, an environmental engineer, met during a conference on sustainable design. Their shared interest in wood as a renewable resource led to the conception of a company that would produce furniture from a single tree. In 2010, they secured initial funding from a venture capital firm that shared their eco-conscious vision. The first prototypes were crafted in a modest workshop in Hamburg, with a focus on ergonomic chairs that could be mass-produced without compromising artisanal quality.
Growth Trajectory
By 2012, 6trees entered the European market through partnerships with boutique furniture retailers. The company’s minimalist aesthetic appealed to a growing segment of consumers seeking sustainable yet stylish home décor. The introduction of the “Single‑Tree Chair” series in 2013 marked a significant milestone, garnering attention in design magazines and securing a place in the portfolio of several design schools. Expansion into the United States began in 2015 through a collaboration with a New York–based distributor, followed by a gradual increase in production capacity to meet rising demand.
Recent Milestones
In 2018, 6trees launched an online platform that provided detailed information on the sourcing of each tree, the processing stages, and the finished product’s life cycle. The platform also offered customization options for color and finish, aligning with the company’s commitment to individualized design. By 2020, the firm had opened a second manufacturing facility in Leipzig, enabling the company to meet both European and North American orders without significant shipping delays. In 2021, 6trees introduced a line of modular office furniture, positioning itself within the corporate sustainability market.
Design Philosophy
Minimalist Aesthetic
The core visual language of 6trees emphasizes simplicity, clean lines, and the inherent beauty of natural wood. The design team avoids excessive ornamentation, instead allowing the grain patterns and subtle variations in tone to become focal points. This approach is consistent with the principles of modernist furniture design, where form follows function and material honesty is paramount.
Functional Ergonomics
Functional ergonomics play a central role in the development of each piece. Designers conduct user studies that evaluate seating angles, lumbar support, and load distribution. Adjustments to leg length, seat depth, and backrest height are informed by anthropometric data, ensuring that the furniture accommodates a wide range of body types. These ergonomic considerations are especially evident in the company’s chair models, which are designed for prolonged use in both domestic and professional settings.
Sustainability as Design Criterion
Design decisions are evaluated against environmental impact metrics. The selection of wood species, the choice of finish, and the manufacturing process are all assessed for their carbon footprint. The company favors fast‑growing hardwoods such as European beech and maple, which provide structural strength while allowing for rapid regeneration of forest resources. Finish choices prioritize non‑toxic, low‑VOC coatings, ensuring that indoor air quality is maintained.

Manufacturing Process
Source Verification
All timber used by 6trees undergoes rigorous verification to ensure it comes from certified, sustainably managed forests. The company works with suppliers that hold certification from recognized bodies, such as the Forest Stewardship Council. Each log is assigned a unique identification number that allows the company to trace its journey from forest to finished product.
Log Preparation
Logs are first inspected for defects and then planed to remove bark. The preparation phase uses low‑energy cutting tools to minimize waste. The log is then fed into a CNC router that mills the furniture’s structural components. The CNC process follows a predefined set of patterns that match the intended design, ensuring precision and consistency across batches.
Assembly and Finishing
Components are assembled using glue and mechanical fasteners that maintain structural integrity while preserving the visual continuity of the wood grain. Finishing involves sanding to a fine grit, followed by the application of a non‑toxic, water‑based varnish. The varnish is applied in multiple layers to protect the surface and enhance the natural appearance of the wood.
Quality Assurance
Each product undergoes a series of quality checks, including dimensional accuracy, surface integrity, and load testing. The company records data from these tests and uses statistical analysis to maintain a defect rate below 0.5%. Products that fail any of the criteria are returned to the assembly line for repair or, if necessary, scrapped and replaced with new components sourced from the same log.
Sustainability Practices
Responsible Forestry
6trees works exclusively with forestry operations that practice selective harvesting, preserve biodiversity, and allow for forest regeneration. The company encourages its suppliers to adopt reduced-impact logging techniques, minimizing soil disturbance and maintaining habitat continuity for wildlife.
Carbon Footprint Management
Carbon accounting is performed for each product category. The company’s lifecycle analysis indicates that a single‑tree chair generates a net carbon footprint of less than 10 kilograms of CO₂ equivalent over its lifecycle, including manufacturing, shipping, and end‑of‑life disposal. 6trees offsets the remaining emissions through a partnership with a reforestation project that plants new trees in deforested regions.
Waste Reduction
The company’s production model focuses on waste minimization. Off‑cuts from milling are recycled into smaller wood products, such as decorative panels or packing material. The use of CNC routing reduces the amount of scrap generated compared to traditional sawmilling. The company also employs a “just‑in‑time” inventory system that limits overproduction.
Product Longevity
Durability is emphasized in the design and construction phases, reducing the need for frequent replacement. The company provides a lifetime guarantee on all structural components, and offers repair kits for common wear items. By extending product life, the overall environmental impact is lowered.

Criticisms and Challenges
Price Point
While 6trees maintains a premium pricing strategy justified by sustainable practices, some critics argue that the cost limits accessibility for middle‑income consumers. Market analyses suggest that price elasticity in the high‑end furniture segment remains moderate, but price sensitivity is a consideration for expansion into broader markets.
Supply Chain Constraints
Dependence on certified forest resources can expose the company to supply shortages, particularly during periods of increased demand or forestry regulation changes. The company mitigates this risk by maintaining an inventory buffer and diversifying its supplier base across several European countries.
Manufacturing Capacity
Scaling production while preserving artisanal quality presents logistical challenges. The company’s current capacity allows for the production of approximately 2,000 units per month. Expanding this capacity without compromising design integrity requires investment in new machinery and skilled labor.
Market Competition
The sustainable furniture market has experienced significant growth, leading to increased competition from both established brands and emerging start‑ups. Differentiation relies on 6trees’ unique single‑tree concept and its comprehensive transparency of sourcing, yet the company must continuously innovate to retain its competitive edge.
