Ask any ergonomist and these two names come up first. Both are genuinely excellent, both cost over $1,200, and both will outlast almost anything else you own. The choice really comes down to two preferences: mesh versus cushion, and how much lumbar adjustability you want.

Comfort and seat
The Aeron's mesh seat keeps you cool and holds its shape for years, but some find the firm edge uncomfortable when sitting cross-legged. The Leap's cushioned seat is more forgiving and lets you sit in more positions.
Lumbar support
The Leap wins here. Its LiveBack system lets you fine-tune lumbar height and firmness to an unusual degree. The Aeron's PostureFit SL is excellent but less adjustable — it's set up for a "correct" posture rather than a custom one.
Which should you buy?
- Aeron — you overheat easily, prefer firm support, and want the iconic look.
- Leap — you want cushion comfort and the deepest lumbar adjustment.
The verdict
Both are exceptional. If we had to pick one for the widest range of bodies, the Leap's adjustability gives it a slight edge — but the Aeron's breathability and timeless design make it the one most people picture when they say "ergonomic chair."
