Evergreen monthly benchmark — May 11
Office Chairs
May 11Rank Trend
How top brands moved week over week. Rank 1 is the top position.
The office chair category has settled into a locked hierarchy: Steelcase/Herman Miller universal duopoly. Branch universal value pick, Haworth/Eurotech as consistent premium-adjacent picks, HON as Claude/Perplexity workhorse pick. This is now the fifth Office Chairs run in your dataset (Mar 26. Apr 5, Apr 22, May 1, May 11) and the brand consensus has solidified. Steelcase and Herman Miller have not been displaced in any run, and Branch has held the value position . Notable run-over-run: Hbada and Sihoo emerging as Claude-specific picks suggest Claude is starting to surface more Amazon-strong mid-tier brands than other models.

How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
