Short answer: the Herman Miller Aeron is the best ergonomic chair if you can afford it. It comes in three sizes, has PostureFit SL lumbar support, a breathable Pellicle mesh seat and back, and a 12-year warranty. The Steelcase Series 1 gives you Steelcase engineering, seat-depth adjustment and LiveBack flex for less. The Branch Ergonomic Chair Pro is the budget pick, with 14 adjustment points including 5D arms and forward tilt.

A chair that does not fit your body cannot support it. The Aeron is sold in three sizes (A, B and C); the one we link is size B, the medium. Steelcase and Branch use one size with more adjustment instead. If you are very short or very tall, check seat height and depth before buying.
Look for support you can position at the curve of your lower back. The Aeron uses PostureFit SL, which supports the base of the spine. The Series 1 and Branch both have adjustable lumbar support.
Seat-depth adjustment lets you keep two or three fingers of space behind your knees, which matters for shorter and taller people. The Series 1 lists seat-depth adjustment. Branch lists 5D arms, which move in more directions so you can bring them close to the desk.
Mesh stays cooler. The Aeron is all mesh and feels firm to some people. Branch combines a mesh back with a foam seat, which many people find softer. The Series 1 uses knit or fabric mesh.
Check the rating: 350 lb for the Aeron and 300 lb for the Series 1. Warranties range from 12 years (Aeron) to 5 years (Series 1) to 2 years (Branch). Branch offers a 30-day trial, which lowers the risk of buying a chair online.
The Aeron is the better long-term chair: three sizes, PostureFit SL, 350 lb capacity and a 12-year warranty. The Series 1 costs less, adds seat-depth adjustment and LiveBack flex, and has a 5-year warranty. Pick the Aeron for all-day use and fit, the Series 1 for value.
Herman Miller makes the Aeron in sizes A (small), B (medium) and C (large). Most people of average height and build fit size B, which is the version we link. Use Herman Miller's sizing guide if you are much shorter or taller than average.
If you sit for many hours a day, a chair that adjusts to you is one of the best things you can buy for your back. You do not need the most expensive model. The right fit and the right adjustments matter more.
Mesh breathes better and keeps you cooler. Foam feels softer at first. The Aeron is full mesh, Branch has a mesh back and foam seat, and the Series 1 uses knit or fabric mesh.
Most people don't when sitting upright to type. A headrest helps if you recline a lot. The base Aeron has no headrest and the Series 1 headrest is sold separately.
Of the chairs we compare, the Branch Ergonomic Chair Pro is the budget pick. It lists 14 adjustment points including 5D arms and forward tilt, assembles in about 20 minutes and comes with a 30-day trial.
