What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Aeron Chair
One whitelisted hands-on reviewer survives verification. Tom's Guide used the standard Herman Miller Aeron for a few weeks and calls it the best office chair if budget allows, praising immediate mesh-seat comfort and fully-assembled delivery while flagging no headrest, limited armrest positioning, and a high price. No lab-measured numbers were reported. TechRadar was dropped because its review covers the separately-marketed Aeron Gaming Chair variant (a distinct SKU with different pricing, configuration, and availability), not the standard office Aeron. (1 sourced review, 1 lab-tested.)
Praised: Immediate mesh-seat comfort that conforms to you from the first sit; Arrives fully assembled, no setup required.
Flagged: No headrest; Armrests can't be adjusted for width/distance from the seat; Expensive.
