Karman Chair: full specs

Specifications

Source: steelcase.com (verified 2026-07-07) · corroborated by tomsguide.com. Re-fetched and adversarially verified 2026-07-10 via fetch-clean.mjs. Source (Steelcase Karman product page) confirms the mesh Intermix textile back with LiveBack technology, the "patented hybrid seat" described verbatim as a "suspension seat with integrated cushioning," the arm options "4D arms or armless" (4D Arm = raise up/down, pivot in/out, shift in all directions), that lumbar support is "Optional," the comfort dial's "four recline positions," and the Steelcase Limited Lifetime Warranty; the page prints no numeric weight capacity, warranty term, or price. Corroboration (Tom's Guide review) supplies the verbatim spec table — "Max weight capacity: 350 pounds" and "Warranty: 12 years" — confirms the "stock Karman comes with 4-way adjustable arms" (4D), that the comfort dial's "first setting locks the backrest in place" (recline lock), and that dedicated/adjustable lumbar is only an optional ~$57 add-on so the standard config ships without it. Two further fetched pages corroborate: BTOD's Nov-2025 review states the four recline options include "an upright lock" and cites a Steelcase.com price of "$1072.00" (verbatim "2025 Price: $1072.00 Where to buy: Steelcase.com"), while thebackstore.com (authorized Steelcase dealer) lists the config-matched base price "$1,114.88" for Standard Chair + Standard 4-Way Adjustable Arms + Standard Lumbar + Standard Wheels for Carpet (Adjustable Lumbar is a +$59.28 upgrade). adjustable_lumbar=false because the standard chair ships with passive built-in LiveBack support and a user-adjustable lumbar module is an optional upgrade; seat_material joins the manufacturer's verbatim "suspension seat with integrated cushioning" with the "Intermix" textile name; back_type="mesh" follows the manufacturer's own "Karman Mesh Ergonomic Office Chair" designation (page title "Karman™ Mesh Ergonomic Office & Desk Chair") and the dataset's suspension-back convention. warranty_years=12 is explicitly stated verbatim in Tom's Guide (note: the Steelcase source instead uses the "Limited Lifetime Warranty" marketing term, a conflict, but 12 is the explicitly-cited numeric figure). release_year and releaseDate are null because no fetched page states a launch year. All 7 non-null spec keys survive verification; priceUsd is anchored to thebackstore.com's verbatim $1,114.88 (rounded to 1115) for the exact spec-matched base config, consistent with BTOD's $1,072 and Tom's Guide's $846–$1,578 range and Steelcase-US pricing.
