Herman Miller vs Steelcase: Which Brand Makes Better Office Chairs?
The Herman Miller Aeron fits through sizing. It comes in three sizes, and each size fixes the seat depth, from 16 inches on size A to 18.5 inches on size C, so the size chosen at purchase decides most of the fit.
The Steelcase Leap V2 fits through adjustment. Its seat depth slides from 15.75 to 18.75 inches, its lumbar adjusts for height and firmness, and its arms adjust in four directions.
Both flagships are covered for 12 years and both reach 400 lb of capacity (the Aeron only in size C). The deciding question for most buyers is whether a sized chair or an adjustable one suits their body better.
Herman Miller tends to suit you if…
- One of the Aeron’s three sizes matches your body, so a fixed seat depth is no drawback
- You want an elastomeric mesh seat (the Aeron’s 8Z Pellicle) with no foam cushion
- You want sacral support from PostureFit SL
- You want a chair you configure at purchase, from tilt options to arm type
- You want an automatic tilt with no dials to set (the Cosm’s Auto-Harmonic Tilt)
- You plan to buy through Herman Miller or an authorized reseller, where the 12-year warranty applies
Steelcase tends to suit you if…
- You need seat depth adjustment to match your thigh length
- You want lumbar firmness control as well as lumbar height (the Leap V2)
- You want 4D arms, or 360-degree arms on the Gesture
- You need 400 lb of capacity, which every Steelcase chair on this page lists
- You want a remanufactured option, since Crandall remanufactures the Leap V2 and the Gesture
- You want a lower entry price, with the Series 1 as the starting point

Brand Overview
Herman Miller
Herman Miller’s current lineup on this page is the Aeron, the Embody and the Cosm, all sold through Herman Miller direct in configurations the buyer chooses. Each carries a 12-year warranty, and that coverage holds only when the chair is bought through Herman Miller or an authorized reseller.
The Aeron’s PostureFit SL supports the sacral region to maintain the natural S-shape of the spine, in Herman Miller’s description. Its seat is 8Z Pellicle, an elastomeric suspension zoned across eight areas of tension with no foam cushion, and its seat depth is fixed by size.
Steelcase
Steelcase’s lineup on this page is the Leap V2, the Gesture and the Series 1, and every one of them lists a 400 lb weight capacity. Warranty coverage is Steelcase Limited Lifetime, with 12-year terms on the parts that wear.
The Leap V2 pairs the LiveBack backrest with a lumbar that adjusts for height and has its own firmness dial. Its seat depth adjusts over about 3 inches of travel, and its listed fit range is roughly 5’0″ to 6’4″.
The Key Difference: Ergonomic Philosophy
Herman Miller handles body variation on the Aeron by selling three sizes. Seat depth and capacity both rise with size, from 16 inches and 300 lb on size A to 18.5 inches and 400 lb on size C. Herman Miller recommends size B for buyers who fall between sizes.
Steelcase handles the same variation on the Leap V2 by adjustment. The seat depth slider runs from 15.75 to 18.75 inches, which spans almost the same range as the three Aeron sizes combined, and the lumbar adjusts for both height and firmness.
Fit is the practical consequence. A buyer between Aeron sizes, or one whose thigh length sits outside a size’s fixed depth, cannot correct it after purchase, while a Leap V2 owner can move the seat pan forward or back at any time.
The Detailed Breakdown
Back Support
The Aeron is configured with one of three lumbar options at purchase. PostureFit SL supports the sacral region, while the standard configuration has no adjustable lumbar. The third option, Adjustable Lumbar Support, adjusts for height and tension according to a BTOD review.
The Leap V2’s LiveBack carries a height-adjustable lumbar plus a separate firmness dial. The lumbar’s height range in inches is not listed in the specifications used here.
Choosing between them comes down to the controls each buyer wants. The Leap V2 lists both lumbar controls, while the Aeron’s lumbar behavior depends on the configuration ordered.
Seat Material
The Aeron’s seat is 8Z Pellicle, an elastomeric suspension with zoned tension across eight zones for weight distribution and no foam cushion. The Leap V2’s seat material is not listed in the specifications this page uses.
Elsewhere in the Steelcase lineup, the Gesture’s seat is high-density foam with fabric upholstery, and the Series 2’s seat is high-density foam with flexible edges. On the Herman Miller side, the Embody uses a four-layer seat with elastic suspension and independently moving support coils.
Buyers who want mesh suspension under them should look at the Aeron, while buyers who want a foam seat have documented options in Steelcase’s Gesture and Series 2.
Adjustability
The Leap V2 adjusts seat height (16 to 20.5 inches), seat depth, tilt tension with a 5-position tilt lock, lumbar height and lumbar firmness. Its arms are 4D.
The Aeron’s adjustments are partly chosen at purchase. Herman Miller offers Harmonic 2 Tilt with tension adjustment, a three-position tilt limiter, or the limiter with forward seat tilt, and five arm configurations up to fully adjustable arms that move in height, pad depth and pivot.
Seat height on the Aeron depends on size, from 14.4 to 19.3 inches on size A up to 15.8 to 22.8 inches on size C. Seat depth does not adjust on any size, so on seat depth the Leap V2 covers through adjustment what the Aeron covers through sizing.
Value and Pricing
The Aeron is sold new through Herman Miller direct at configuration-dependent prices, so its cost depends on the options chosen. The Leap V2’s Amazon figure appears in the table above, and readers weighing other routes can compare Herman Miller alternatives across several brands.
Remanufactured chairs narrow the gap. Crandall Office remanufactures the Aeron Classic, the older pre-2016 Aeron design, and the current Aeron’s specifications do not apply to it. Crandall remanufactures the Leap V2 as well, on the same 12-year parts warranty with free returns, so the used route is open on both sides of this comparison.
Design and Aesthetics
Appearance is a matter of preference that specifications do not settle, so this section sticks to listed materials. Herman Miller states the current Aeron contains more than 50% recycled material by weight, including ocean-bound plastic, and the Embody uses a die-cast aluminum frame and base. On the Steelcase side, the Series 1 carries CarbonNeutral product certification and the Gesture offers it as an option.

Which Brand Should You Choose?
Most buyers are better served choosing a specific chair from either brand. The specifications that separate these chairs are seat depth, lumbar controls, arm movement and capacity, and they vary as much within each brand as between them.
If one of the Aeron’s three sizes matches your body and you want a mesh suspension seat, the Herman Miller Aeron is the chair to configure. Size choice matters more on the Aeron than any brand trait, since seat depth and capacity are both set by size.
If you need seat depth adjustment or lumbar firmness control, the Steelcase Leap V2 offers both with a 400 lb capacity. The Natural Glide recline and 4D arms complete its adjustment set.
If you want arms that turn 360 degrees, the Steelcase Gesture is the chair on this page whose arms are specified that way.
If you want Pixelated Support and an adjustable seat depth from Herman Miller, the Embody offers both, with a 300 lb capacity.
