Healthy Spine

The Saddle and Pony's unique, triangular cushion encourages users to sit in a "saddle" posture, which lowers the thighs, opens up the hips and puts the spine into a healthy lordotic curve (S-Curve). The "saddle" posture also reduces pressure points for long-term comfort.

Active Sitting

(Active Pony Only)

Active Pony's 7-degree tilt lends subtle, healthy motion as you work, keeping you better engaged and boosting circulation. It's designed to adjust to you, never the other way around.

The Design Story

An icon, 60 years in the making.

Designed by Niels Diffrient.

Recognized as the father of ergonomics, legendary designer Niels Diffrient focused on the human experience to inspire innovative products. He revolutionized task seating by inventing a chair that adjusts to the sitter, rather than making the sitter adjust to the chair.
