Does no mention mean a brand is invisible to AI?

No. Absence means the brand was not recorded in this limited set of prompts and usable answers. It does not establish absence from other AI answers.

How often is Steelcase mentioned?

Steelcase appeared in 11 usable answers in this snapshot. A mention is not necessarily a recommendation.

Which brands appear most in the budget answers?

Branch, HON appeared in 4 of 4 usable budget answers each. This measures mentions, not verified price or budget compliance.

Does this benchmark prove AI recommendations are biased?

No. Differences in answers do not establish bias or prove that advertising or commercial integrations caused a recommendation. Model, tier and collection changes can also affect comparisons.

Key takeaway

For a remote developer with back pain, AI routes to Steelcase and Herman Miller as the premium default in every engine, with Branch as the value pick that shows up across all four and HON owning the under-500 workhorse slot. A challenger outside that core is nearly invisible - and the engines actively recommend buying a refurbished premium chair over a new budget one, which is a structural headwind for any new brand. Branch is the one DTC brand that has genuinely broken in.

What This Means

Steelcase is the unanimous aggregate #1 across all four engines - the cleanest top-pick consensus in this category, driven by the Leap and Gesture and 12-year warranties.
Herman Miller holds a top-3 slot in three of four engines as the premium alternative.
The volume-versus-authority split is stark: Branch is one of the most-mentioned brands (10 mentions, cross-model value presence in every engine) yet sits outside every single engine's top 3 - mentioned constantly, top-picked never.
The engines diverge only in the value tier below the top two: ChatGPT elevates Haworth to #2 (its Soji value pick) and price-tags a dozen-plus SKUs; Claude and Perplexity both place HON second on its under-500 workhorse strength and lifetime warranty; Gemini uniquely puts Eurotech Vera in its top 3 on back-pain grounds.
ChatGPT is the broadest commerce surface; Claude is the most refurbished-forward, naming Crandall and BTOD; Gemini is the most comparison-table-driven and leads with the Leap V2; Perplexity is the only engine to lead its discovery prompt with the Gesture rather than the Leap and uniquely surfaces Secretlab.
The Leap-versus-Gesture split and the HON-versus-Haworth value divergence are the main fault lines.

Findings and Limitations

The category is locked around three legacy contract-furniture brands (Steelcase, Herman Miller, Haworth) plus Branch as the one modern DTC brand to break in, and the barrier is brand pedigree and warranty rather than product features.
Refurbished premium is a recurring recommendation that itself squeezes challengers - engines tell buyers to get a used Leap over a new budget chair.
Absent despite real presence: Autonomous appears only in the value tier, Secretlab only once, and the entire ergonomic-DTC wave (X-Chair, Sihoo beyond one model, FlexiSpot beyond one model, Vari seating, Fully) is nearly invisible.
Gaming-chair brands are actively steered against.
No sub-300 brand holds cross-model agreement.

Recurring themes in the answers

The brands AI favors share deep adjustability (seat-depth adjustment and 4D armrests cited as the non-negotiables for 8-hour developer use), strong multi-year warranties (Steelcase and Branch 12-year, HON lifetime cited as trust signals), lumbar support tuned for lower-back pain, and commercial-grade durability.
