About ChairAtlas

ChairAtlas is an independent reference site for high-end ergonomic office chairs. We help you cut through incomplete retailer pages, conflicting forum advice, and hard-to-read manufacturer PDFs—so you can compare models on the specs that actually matter.

Each chair page covers body fit (height range and weight capacity), seat and back dimensions, arm and lumbar options, generation differences, serial-tag tips, and typical new, refurbished, and used price ranges for Herman Miller, Steelcase, Haworth, and Humanscale.

Mechanical and dimensional fields come primarily from manufacturer product sheets, cut sheets, and official store specification blocks (North America unless noted). Each chair record lists its sources and a last verified date.

• Capacity and warranty tiers come from manufacturer product pages or current product sheets— including config footnotes such as Aeron sizes and Haworth forward-tilt capacity splits.
• Seat height, depth, and width come from product sheets, cut sheets, or official store Dimensions blocks.
• Body height envelopes use manufacturer feet/inches when published. Otherwise we derive a practical research default and document the caveat on the chair page.
• Prices (MSRP, typical refurbished, typical used) are approximate market references for filtering—not live quotes.

We also assign a data-confidence level (high, medium, or needs review) so you can see how closely core specs match current manufacturer literature.

We are not a dealer, manufacturer, or authorized reseller. We do not take inventory, set retail prices, or speak for Herman Miller, Steelcase, Haworth, or Humanscale. Specs can change; always confirm critical numbers on the seller’s listing and the brand’s current literature before you buy.
