Ergo Score · 91 / 100
The best chair for adjustable lumbar support and all-day cushion comfort. A lifetime frame warranty seals the deal[1].
Where the Aeron leans on a firm mesh, the Leap uses a flexible, cushioned back and seat that move with you. Its defining feature is the LiveBack system, which lets you dial lumbar height and firmness to fit your lower back precisely — something the Aeron can't match.

What we like
- Deep lumbar adjustment — height and firmness, not a fixed bump.
- Forgiving seat — comfortable in more positions than the Aeron.
- Flexible back — the backrest moves with your spine.
What we don't like
- Warmer than mesh — cushion retains more heat than the Aeron.
- Looks — more conventional than the Aeron's iconic silhouette.
Who it's for
Choose the Leap if lumbar support is your top concern or you want a softer, more cushioned feel. If you run hot or prefer firm support, the Aeron is the better pick.
The verdict
The Leap is a superb chair and arguably the most adjustable in its class. For bodies with specific lower-back needs, it's our top recommendation.
