Office Chair Reviews Built Around How You Actually Sit
SeatedLab compares office chairs on the specs that decide fit and on the warranty behind each chair.
Chair Reviews
Herman Miller Aeron
Seat depth comes from the size you order (A, B or C, at 16, 17 or 18.5 inches), and no slider fixes a wrong choice later. There’s no foam cushion either: the 8Z Pellicle seat is an elastomeric suspension with its tension zoned across eight areas.
Read full review →Steelcase Leap V2
For a lower back that needs dialing in, the Leap V2 gives you two separate lumbar controls, height and firmness. The seat slides about 3 inches for depth, and Crandall’s remanufactured unit comes with Crandall’s own 12-year warranty.
Read full review →Herman Miller Embody
Pick the Embody over the Aeron if a fixed seat worries you: its seat slides from 15 to 18 inches, so you set depth yourself instead of choosing it at checkout. Heavier sitters should look at the weight rating first, since it tops out at 300 lb against 400 lb on every Steelcase chair here.
Read full review →Steelcase Gesture
If your forearms need support in more than one position, start with the Gesture’s 360-degree arms, which adjust for height, width, depth and pivot. Lumbar firmness sets itself by recline angle through Core Equalizer. A height-adjustable lumbar is an optional add-on.
Read full review →Herman Miller Cosm
The Cosm is for someone who wants to sit down and leave the controls alone. Its lumbar suspension has no height or firmness setting, and the tilt has no recline lock. The catch is a seat fixed at 15.9 inches deep, which fits shorter thighs better than long ones.
Read full review →Secretlab Titan Evo
Choose the Titan Evo for gaming-chair styling with built-in lumbar that adjusts for height and depth. If the styling doesn’t matter, the Steelcase Series 2 costs about the same and carries a 12-year warranty against the Titan’s 3 years, extendable to 5.
Read full review →Branch Ergonomic Chair
The Branch is the least expensive chair on this page, and it still slides its seat for depth. It has eight adjustments, including 3D arms and height-adjustable lumbar, and Branch states a fit of 5’2″ to 6’2″. Before ordering, note the 275 lb rating and 7-year warranty.
Read full review →Branch Ergonomic Chair Pro
Move up to the Pro when the standard Branch runs out of adjustment. It has 14 adjustments against eight, including forward seat tilt, and its lumbar adjusts for depth as well as height.
Read full review →Steelcase Series 2
This is the Steelcase to buy for a seat depth slider and 4D arms without paying Leap V2 money. The slider gives 2.75 inches of travel, the lumbar is height-adjustable, and the chair is rated to 400 lb. Skip it if you want a headrest, since the Series 2 has no headrest option.
Read full review →Steelcase Series 1
The cheapest Steelcase here keeps the Leap V2’s 400 lb rating. What you give up is lumbar control: height only, firmness fixed. The seat still slides for depth, and the arms move in four directions.

How SeatedLab Works
Check seat depth and weight rating before anything else: lumbar and arms adjust on most chairs here, but a seat fixed too deep or a rating below your weight cannot be changed after delivery. Every review is based on manufacturer specifications and published owner reviews.
