Source: hermanmiller.com (verified 2026-07-08) · corroborated by store.hermanmiller.com. The official Herman Miller specs page (source) confirms the "12-year, 3-shift warranty" (warranty_years=12), Auto-Harmonic Tilt, Intercept elastomeric "suspension at the seat and back", the three back heights (Low/Mid/High), and arm styles (Leaf, Height-Adjustable, Fixed, No Arms). The store.hermanmiller.com Cosm Mid Back product page (corroboration) confirms verbatim "Weight Capacity (lbs): 350" (max_weight_lb=350), the material "Intercept polyester elastomeric seat mesh" (seat_material), the "12-year warranty", the displayed price "$1,850", "seat mesh"/"Intercept suspension at the seat and back" (back_type=mesh), and the Fixed Arm description "Arms are set at 8.6\" above the seat and cannot be adjusted" (armrests=fixed non-adjustable). adjustable_lumbar=false and recline_lock=false are supported by "Provides total, weightless support – no adjustments necessary" plus the Auto-Harmonic Tilt being automatic ("instantly and automatically provides balanced support and movement"), with no lumbar or tilt-lock option in the configuration list. No fetched page states a release year (only a 2019 Time "100 Best Inventions" mention, not a release date), so release_year and releaseDate are null. Correction: the original priceUsd=1585 and the "$1,585 to $2,060"/btod arm-upgrade pricing are NOT present in either fetched page; the only verbatim price is $1,850, so priceUsd was corrected to 1850 and the unverifiable pricing claims removed. Model/config matches (Cosm Chair, Mid-Back) with no sibling/variant mismatch; all 8 spec keys survive verification.
