In the field of wearable assistance systems, Carl Stahl is closely associated with the Chairless Chair, a passive lower‑limb exoskeleton originally developed by the Swiss company noonee. Carl Stahl initially acted as a distribution partner for the Chairless Chair before acquiring noonee in June 2024. Through this acquisition, Carl Stahl assumed full responsibility for the production, further development, and global distribution of the Chairless Chair.

Today, Carl Stahl acts as the manufacturer and system provider of the Chairless Chair 2.0. The company focuses on scaling the technology for industrial use and positioning it as a workplace‑ready solution for activities involving prolonged standing or alternating sit‑stand tasks.

In addition, under the noonee brand, Carl Stahl has operated an international exoskeleton marketplace since early 2026. This digital platform offers a broad portfolio of exoskeleton solutions for multiple industrial sectors and a wide range of occupational activities, including manufacturing, assembly, logistics, maintenance, and manual handling. The marketplace is designed to provide access to manufacturer‑independent solutions, supporting users and companies in identifying suitable exoskeletons for specific tasks and application scenarios.
