How it works

From the desk
to the report.

A seated assessment starts from one side photo, in the same app as your standing posture exams.

  • 01

    Photograph the workstation

    Take a side photo of your client seated at their desk, or import one. In the photo, the client faces to your right.

  • 02

    Mark the landmarks

    The landmark points go on the side photo, the monitor included. You review every point.

  • 03

    Read the angles

    SitScreen lists the ten seated angles as right view deviations, beside the marked-up photo.

  • 04

    Report and compare

    Share a professional report, and compare seated assessments to see how your client responds to your intervention.

Who it’s for

Made for the desk,
and the people at it.

For professionals who look at how clients work: SitScreen gives accurate and precise seated lateral analysis, to better evaluate work ergonomic environments.

  • Work ergonomics. Document how a client really sits at their workstation: head, neck, upper back, arms and hips in one side view.
  • Standing and seated, together. Use standing neutral posture analysis along with seated posture analysis, for better documentation for your clients.
  • Before and after. Use seated assessments with the comparison report to objectively gauge a client’s response to your intervention.
  • Used in research. As of October 2026, researchers have used SitScreen to measure seated posture in 3 published studies.
