Office Chair Reviews Built Around How You Actually Sit
SeatedLab reviews ergonomic office chairs by sitting style and body type, so each pick names the sitter it suits. Every review is based on manufacturer specifications and published owner reviews.
Chair Reviews
Each review covers a chair’s adjustment ranges and warranty, then names the body types and sitting styles it fits.
Herman Miller Aeron
A task chair sold in sizes A, B and C with seat depth fixed by size from 16 to 18.5 inches. The 8Z Pellicle seat is an elastomeric suspension with no foam cushion, and PostureFit SL lumbar supports the sacral region.
Read full review →Steelcase Leap V2
The LiveBack back carries lumbar that adjusts for height, with a separate firmness dial. The seat depth slider gives roughly 3 inches of travel, the chair is rated to 400 lb, and Crandall remanufactures it with a 12-year warranty.
Read full review →Herman Miller Embody
Herman Miller says BackFit “lets you fine-tune the chair specifically to your spine, and then adapts to your movement,” and Pixelated Support runs through both seat and back. The seat depth adjusts from 15 to 18 inches, against the Aeron’s depth fixed by size, and the weight rating is 300 lb.
Read full review →Steelcase Gesture
The 360-degree arms adjust for height, width, pivot and depth, and the seat depth slider runs from 15.75 to 18.5 inches. Core Equalizer lumbar sets its firmness automatically by recline angle, and an optional height-adjustable lumbar adds a 4-inch range.
Read full review →Herman Miller Cosm
Auto-Harmonic Tilt has no tension dial and no recline lock, and Intercept suspension lumbar has no height or firmness control. The 15.9-inch seat depth is fixed, which suits shorter thighs better than long ones, and the weight rating is 350 lb.
Read full review →Secretlab Titan Evo
A gaming-style chair with built-in 4-way lumbar that adjusts for height and depth, and a 3-year warranty extendable to 5. If you do not need gaming-chair styling, the Steelcase Series 2 costs about the same and has a 2.75-inch seat depth slider.
Read full review →Branch Ergonomic Chair
The Branch has eight adjustment points, including 3D arms and height-adjustable lumbar with fixed firmness. Its 275 lb weight rating and 7-year warranty both sit below the Series 1, which is rated to 400 lb with a 12-year warranty.
Read full review →Branch Ergonomic Chair Pro
The Pro raises the standard Branch’s eight adjustment points to 14, adding 5D arms and forward seat tilt. Its lumbar adjusts for height and depth and can be removed entirely.
Read full review →Steelcase Series 2
The Air LiveBack uses a geometric flexor pattern, with height-adjustable lumbar built into the back. A 2.75-inch seat depth slider and 4D arms come standard, and the 12-year warranty matches the Leap V2’s.
Read full review →Steelcase Series 1
The Series 1 shares the Leap V2’s 400 lb rating at the lowest price of the four Steelcase picks here. Lumbar adjusts for height only, with fixed firmness, while a seat depth slider and 4D arms cover the rest of the fit.
Read full review →HON Ignition 2.0
A mesh-back task chair with synchro-tilt and adjustable lumbar, rated to 300 lb. The seat slides for depth, and the arms adjust for height and width. HON also sells a version with a headrest, priced separately above.

How SeatedLab Works
Fit depends on body size as much as on price. The Cosm’s seat pan is fixed at 15.9 inches, while the Leap V2’s slider runs from 15.75 to 18.75 inches, so a sitter with long thighs can adjust one chair and not the other.
Each review also names the body types and sitting styles a chair does not suit, so a mismatch shows up before you buy.
