Evergreen monthly benchmark — Sep 11
Office Chairs
Sep 11Rank Trend
How top brands moved week over week. Rank 1 is the top position.
Steelcase was ranked first in all eight cells that did not mention a price. Herman Miller was second in all seven of its appearances and Haworth third in all four of its own. The podium is identical on every engine and nothing displaces it. Steelcase is also the only premium brand to survive the budget prompt, and it gets there secondhand.
Top Brands by AI Mention Frequency
Mention frequency counts how many times a brand appeared across all AI responses. This differs from top-pick rank, which reflects each model’s #1 choice.
Opportunity for Brands
- Five of the fourteen brands were named by exactly one engine.
- Sihoo is the sharpest case of a brand that exists only under a price ceiling.
- All four engines name it and not one names it on a prompt without a budget.
- Branch is the only value brand that crosses over, reaching all four engines and both open prompts.
- Staples and Nouhaus are each named more than once and never rank above fourth anywhere.

All 4 models agree on Steelcase as the top pick
What This Means
- The engines return the same first three brands on both prompts that do not mention a price.
- ChatGPT ranges widest with ten distinct brands and Claude narrowest with five.
- Perplexity is the only engine to rank Uplift, and it does so on both prompts where Uplift appears.
- Gemini alone names Eurotech and Colamy, and Colamy takes its top slot under the budget ceiling.
- Only Perplexity reaches outside task seating, ranking the Secretlab Titan Evo fifth.
Why These Brands Win
- Adjustable lumbar height and firmness is the first feature every engine screens for.
- Seat depth adjustment is the second, and all four tie it to keeping the pelvis from tilting forward.
- Every engine said a chair is not a treatment for back pain and most advised seeing a clinician.
- All four told the reader to change position every thirty to sixty minutes regardless of the chair.
- Fit to the individual body is described as mattering more than the brand by every engine in the set.

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
