What this listing is: Series 2 in Graphite on a light frame
This is the Steelcase Series 2 task chair, listed with a colour of Graphite / Light Frame and a manufacturer part number of 436AIR3D-6295-5T29-5S25-7243-4ARM-LUM-HF. The listing's model number field just says Series 2. Steelcase's Series 2 page lists the back styles as Air, 3D Microknit, upholstery, quilted upholstery and a fabric back cover.
The Series 2 page we read does not publish the colour or option codes, so we cannot decode this part number against a Steelcase document. Use the listing photos and the Graphite / Light Frame colour field to confirm the look you want. The included-components field lists only the office chair, and Steelcase lists the headrest and coat hanger as accessories, so do not expect either in the box.
The adjustments Steelcase names
Steelcase's hang tag labels seat depth adjustment, seat height adjustment, a comfort dial with three recline settings named full recline, boosted recline and upright, height-adjustable lumbar support, flexible seat edges and four-dimensional arms that adjust in height, depth, width and pivot. The product page describes the mechanism as weight-activated.
The Air LiveBack back is described on the hang tag as a geometric wave pattern that flexes in two dimensions. The hang tag also says the back upholstery can be replaced without replacing the entire back frame. That matters if you expect heavy wear on the fabric, because the cover is a separate part from the structure behind it.
Which backs get the height-adjustable lumbar
Steelcase is specific about lumbar. Its product page says height-adjustable lumbar is standard on upholstered or 3D Microknit options, and the hang tag's lumbar callout carries the same qualifier: on upholstered and 3D Microknit backs. Neither document says the Air back option carries the same sliding lumbar.
The listing bullet says the chair offers Air LiveBack technology with adjustable, flexible lumbar support, and the part number begins 436AIR3D. We could not confirm from a Steelcase document whether this unit's back is an Air back or a 3D Microknit back. If the sliding lumbar matters to you, check the photos for the lumbar handles and ask the seller before ordering.
Carpet casters, hard floor, or both? The listing cannot decide
The listing title says Carpet Floors and the style field says Carpet Casters. The item-details table lists the surface recommendation as Hard Floor, one bullet says the chair has wheels for hard flooring, and the part number ends in HF. That is three hard-floor signals against two carpet signals on one product page.
Neither Steelcase document we read for Series 2 states which caster is standard or what the HF suffix means. Before you buy, ask the seller which caster is fitted, or plan on a chair mat if you are putting it on a floor the listing may not suit.
Size and assembly figures come from the listing
Amazon's measurements give 22 inches deep, 27 inches wide and 42.5 inches high, a separate item depth of 20.625 inches, an item weight of 36 pounds, a seat depth of 17.75 inches and a seat back interior height of 22.5 inches. We found no Steelcase dimension table for Series 2, so these are retail figures only.
The listing's assembly field says one person can put it together in under two minutes from four parts with no tools. The table also carries entries that do not fit this chair, including a shape of L-Shaped, a leg style of Tapered Leg and a finish type of Off White, so check anything that affects fit against the photos.
400 pounds, 12 years, and the retail warranty question
Steelcase's product page says the Series 2 chair and stool handle weight up to 400 pounds, and the hang tag says weight tested and warranted to 400 pounds, matching the listing's 400-pound field. Both Steelcase documents describe a 12-year, 24/7 multi-shift Limited Lifetime Warranty, and the listing's warranty field says 12 year manufacturer.
The Americas warranty PDF gives seating mechanisms, lumbar mechanisms, headrests, cylinders, arm caps, foam and casters a 12-year term. It also says it does not apply to products sold at retail to consumers, who are pointed to a separate consumer warranty we could not find. Steelcase's store FAQ says that consumer warranty applies only to purchases from store.steelcase.com or a Steelcase Authorized Retailer by buyers in the United States or Canada.
The same PDF lets Steelcase reject claims on products bought from unauthorised sellers, including unauthorised internet sites. Before buying, check who the seller is on the offer you select, and ask Steelcase whether that seller is authorised.
