The Problem

Your chair costs $1,500.
Your base costs you your hips.

Every office chair on earth sits on a 5-star caster base. The base and the seat are decoupled. The seat swivels on a gas cylinder. The base stays wherever the casters last rolled.

Every time you sit down, your feet find a different geometry. The casters drift. They end up under your foot, or between your feet, or angled wrong. Your foot compensates. Your ankle adjusts. Your knee follows. Your hip absorbs it.

Eight hours a day. Five days a week. Fifty weeks a year.

Humanscale spent 20 years perfecting the mechanism. Nobody spent 20 minutes thinking about the base.
The Fix

Two innovations. Zero hip drift.

Indexed Rotation. The base rotates with the seat. When you swivel, the star follows. Your feet always land in the same position relative to your body.

Caster Straighteners. Each caster locks to point outward along the arm. The wheel still rolls freely. But it can’t drift sideways into your foot path.

Combined: the base tracks with the seat AND the casters stay aligned. Your hips receive identical geometry every sit. The micro-adjustments that accumulate into chronic pain are eliminated at the source.
