R.U.M. Sledge - Keyboard Black

R.U.M. Sledge – Keyboard Black is a minimalist, sustainable design chair featuring a durable steel sledge/cantilever frame. Formulated from recycled E-waste plastic, it is engineered to meet the highest demands of agile corporate workspaces, contemporary seminar rooms, and professional B2B contract environments.

E-waste products consist of reused plastic materials from discarded electronic devices. With technological appliances being produced and consumed to a large extent—making it the fastest-growing waste stream in Europe—it is vital to reuse the considerable amount of E-waste that naturally arises from global consumption. All the E-waste material utilized in this specific Wehlers architectural chair is sourced from Europe and processed to meet rigid high-traffic standards.

Performance & Functionality - Designed with a stackable mindset, the Keyboard Black Sledge model offers a perfect balance between flexible ergonomic movement and absolute structural stability. It is the ideal high-traffic choice for commercial workspace projects, multi-purpose auditoriums, and design-forward office areas that prioritize architectural clarity and deep carbon reductions.

Design - The iconic architectural expression of the chair was created by C.F. Møller Design, an integral part of C.F. Møller Architects—one of Scandinavia's oldest and largest architectural firms. Their and our vision is to improve the lives of people and the planet. C.F. Møller Design describes the creation of R.U.M. as a friendly, comfortable, and practical architectural chair, optimized beautifully for corporate offices, public spaces, and private homes.

Sustainability & B-Corp Certification - R.U.M. stands for Re-Used Materials. As a certified B-Corp, Wehlers anchors this product in a strict circular economy framework. The entire design process follows a circular thinking approach: only two primary materials are used in the production of the R.U.M. chair, ensuring that 100% of the components can be recycled continuously for new Wehlers furniture through our official Take-Back System.
