What it changes

Change the seat, not the chair

The problem isn't how long you sit: it's the distribution. A flat seat puts the whole weight of the torso on a small surface. A well-placed cut-out shifts the load to the thighs and sit bones.

  • Sits on any seat in seconds
  • Office, car, dining room, armchair
  • It raises you: remember to readjust the seat height

After an hour, the seat gets hard

You shift your pelvis, sit on one buttock, get up to walk for two minutes. The pressure point always ends up reminding you it's there.

A flat seat puts the whole weight of the torso on a small surface. It's the distribution that's the problem, not the duration.

The U-shaped cut-out frees the rear pressure point and shifts the load to the thighs and sit bones.
