I'm sorry, but the available search results do not contain information about the ending of the full first season of The Chair Company (2025). The results only cover the premiere and second episode, detailing early plot developments and character arcs, but do not describe the season finale or the ultimate fates of the main characters.

If you would like a detailed, scene-by-scene summary of the episodes that have aired so far (Episodes 1 and 2), I can provide that. However, a summary of the season's ending is not possible with the current information. Please let me know if you would like the detailed episode recaps that are available.

In the 2025 TV show The Chair Company, no characters are reported to die in the episodes released or described so far. The series, which follows Ron Trosper investigating a conspiracy after a workplace incident, focuses on suspense, psychological tension, and dark comedy rather than character deaths.

Available episode summaries and reviews up to October 2025 do not mention any deaths among the main or recurring characters. The show's tone is more about paranoia, investigation, and personal unraveling than fatal outcomes.

Therefore, as of the current information, no character deaths occur in The Chair Company and no circumstances of death are described.
