Where each one wins

Why the Herman Miller Aeron still makes sense

  • Higher Quality (96 vs 90): 8Z Pellicle mesh with eight tension zones and no foam to compress over time.
  • Three frame sizes (A, B and C) fit the chair to your body, and a forward-tilt setting suits people who lean into the desk.
  • Mesh seat and back breathe better for people who run warm; the Leap's foam holds heat by comparison.

Why the Steelcase Leap scores higher

  • Higher Value (60 vs 57) and Features (86 vs 80): $1,398.91 against $1,649.99, with seat-depth adjustment and 4D arms the Aeron lacks.
  • Perfect Warranty (100 vs 96): 12 years, 24/7, parts and labor on both, and the Leap is the only chair in the category to score 100.
  • A 400 lb weight rating (500 lb on the Leap Plus) and a seat that glides forward as you recline.

Questions buyers ask

Is the Herman Miller Aeron or Steelcase Leap better for people who run hot?

The Aeron. Its seat and back are all mesh with no foam, while the Leap's foam seat holds more heat.

Which chair has more adjustments, the Aeron or the Leap?

The Leap: it adds seat-depth adjustment, arm-width adjustment and lumbar firmness control. The Aeron relies on three frame sizes instead of a seat-depth slider.

How long will the Aeron and Leap last?

Both carry a 12-year, 24/7 parts-and-labor warranty. Steelcase notes the Leap's seat foam softens after 5 to 8 years of heavy use; the Aeron has no foam to compress.
