Which is better for long workdays?

Both hold up for eight-hour days. The Pro lets you tune armrests, lumbar and seat tilt more precisely; the Aeron's suspension stays cooler and resists sagging over years.

The Aeron has the longer track record and a 12-year warranty against the Pro's 7 years. The Pro's mesh and frame are solid, but its foam and fabric options will show wear sooner than Pellicle.

Is the Pro worth stepping up to over the Aeron?

Step up to the Pro if fit tuning and a headrest matter more to you. Step up to the Aeron if you want the longer warranty and proven durability.

Does the Aeron come in sizes?

Yes, sizes A, B and C. The Pro comes in one size, so check the 275 lb capacity and seat range against your body first.

Which is easier to assemble?

The Aeron arrives mostly assembled and takes about 10 minutes. The Pro ships flat-pack and needs full assembly, though owners call the directions clear.

Which has better lumbar support?

The Pro's lumbar adjusts in height and depth and can be removed. The Aeron's PostureFit SL is fixed but shaped to support the lower back and sacrum.

Branch Ergonomic Chair Pro vs Herman Miller Aeron

The Ergonomic Chair Pro is the more adjustable chair: 14 adjustment points, 5D armrests, forward seat tilt and a two-way lumbar support that comes out. The Aeron is the better-built and longer-proven chair, with its 8Z Pellicle suspension and a 12-year warranty that owners rely on. Reviewers of the Pro call it cloud-comfortable and easy to assemble; Aeron owners praise the mesh's all-day breathability and durability. Buy the Pro for maximum fit tuning and material choice; buy the Aeron for a proven long-haul chair.

Choose the Ergonomic Chair Pro if you want the most adjustment points and a choice of mesh, bouclé, vegan leather or leather, plus an optional headrest.
Choose the Aeron if you want a proven suspension chair with a 12-year warranty and three frame sizes to fit your body.
